Traffic Management

This chapter describes Arista’s Traffic Management, including configuration instructions and command descriptions. Topics covered by this chapter include:

Traffic Management Conceptual Overview

Traffic is managed through policy maps that apply data shaping methods to specific data streams. A policy map is a data structure that identifies specific data streams and then defines shaping parameters that modify packets within the streams. The switch defines four types of policies:
A policy map consists of classes. Each class contains an eponymous class map and traffic resolution commands.
  • A class map is a data structure that defines a data stream by specifying characteristics of data packets that comprise that stream. Each class map is typed as either QoS, control plane, or PBR and is available only to identically typed policy maps.
  • Traffic resolution commands specify data handling methods for traffic that matches a class map. Traffic resolution options vary by policy map type.

Data packets that enter an entity to which a policy map is assigned are managed with traffic resolution commands of the first class that matches the packets.

Control Plane Policies

The switch defines one control plane policy map named copp-system-policy. The copp-system-policy policy map is always applied to the control plane and cannot be removed from the switch. Other control plane policy maps cannot be added. Copp-system-policy consists of preconfigured classes, each containing a static class map and traffic resolution commands. Preconfigured classes cannot be removed from copp-system-policy.

Static class maps are provided by the switch and cannot be modified or deleted. The naming convention of static class maps is copp-system- name, where name differentiates the class maps. Static class maps have pre-defined internal conditions, are not based on ACLs, and are only listed in running-config as components of copp-system-policy. The sequence of static class maps in the policy map is not significant. Traffic resolution commands define minimum (bandwidth) and maximum (shape) transmission rates for data streams matching the corresponding class map.

Copp-system-policy can be modified through the following steps:
  1. Add classes consisting of an eponymous dynamic class map and traffic resolution commands.

    Dynamic class maps are user created, can be edited or deleted, filter traffic with a single IPv4 ACL, and are listed in running-config.

  2. Change traffic resolution commands for a preconfigured class.
These sections describe control plane traffic policy configuration procedures:

QoS Policies

QoS policy maps are user defined. The switch does not provide preconfigured QoS policy maps and in the default configuration, policy maps are not applied to any Ethernet or port channel interface. Policy maps and class maps are created and applied to interfaces through configuration commands.

A QoS policy map is composed of one or more classes. Each class contains an eponymous dynamic class map and traffic resolution commands. Dynamic class maps are user created, can be edited or deleted, filter traffic with a single IPv4 ACL, and are listed in running-config.

QoS traffic resolution commands perform one of the following:
  • Set the Layer 2 CoS field
  • Set the DSCP value in the ToS byte
  • Specify a traffic class queue
The last class in all QoS policy maps is class-default, which is composed as follows:
  • The class-default class map matches all traffic except IPv4 or IPv6 traffic and is not editable.
  • By default, class-default class contains no traffic resolution commands. Traffic resolution commands can be added through configuration commands.

Data packets that enter an interface to which a policy map is assigned are managed with traffic resolution commands that correspond to the first class that matches the packet.

These sections describe QoS traffic policy configuration procedures:

Segment Routing Traffic Engineering Policy (SR-TE)

Segment Routing Traffic Engineering Policy (SR-TE) policy uses Segment Routing (SR) to enable a headend to steer traffic along any path without maintaining per flow state in every node based on the policy. Configuring SR policy for the MPLS dataplane (SR-MPLS) for Type-1 SR policy segments with BGP and locally configured policies as sources of SR policy is available on DCS-7500 and DCS-7280 family of switches.

SR Policy Overview

SR Policy Identification
The following identifies an SR policy.
  • Endpoint: an IPv4 or IPv6 address which refers to the destination of the policy. (0/0, 0:: are allowed and called “null endpoints”)
  • Color: an unsigned 32-bit opaque numerical quantity. The semantic of a color is up to the operator. It can refer to, for instance, an application or a type of traffic (low latency) or a geographical location, etc.
SR Policy Constituents
The SR policy consists of candidate paths. Each candidate path has the following.
  • SID-lists (SLs): an ordered list of Segment Identifiers. (Each SID is a MPLS label in the MPLS instantiation of SR). An SL encodes one path from the headend to the destination. Each SL has an optional weight attached to it for the purpose of Unequal Cost Multipath (UCMP) traffic distribution. The default value for SL weight is 1.
  • Preference: an optional, unsigned 32-bit integer used in the candidate path selection algorithm to select the “active” candidate path. The default value for preference is 100.
  • Binding SID (BSID): an optional, SID.
    Note: In EOS, a BSID is mandatory for each candidate path.
SR Policy Sources
A headend learns SR policies using the following.
  • BGP
    • Single agent routing model (Ribd)
    • Multi-agent routing model
  • Local configuration using CLI
    • Single agent routing model (Ribd)
    • Multi-agent routing model
    • Openconfig YANG models
  • PCEP
    Note: PCEP is not supported in EOS.

Identity of a Candidate Path

A candidate path within an SR policy is identified by a 3-tuple of {Protocol-Origin, Originator, Discriminator}. In EOS, for locally configured policies:
  • the ASN in the Originator is set to 0.
  • the node address in the Originator is set to 0.0.0.0.
  • discriminator is set to the Preference configured.
    Note: EOS CLI allows configuring only one candidate path at a given preference and does not allow configuring the discriminator for a candidate path.

State of an SID List (SL)

The following describes the state of an SL.
  • Valid: the top label of the SL is resolvable within the LFIB to outgoing next hop(s), interface(s) and a label action.
  • Invalid: top label of the SL is not resolvable to outgoing next hop(s), interface(s) and a label action. An SL is also marked as invalid when the SL is resolvable, but the resolved labeled stack exceeds the platform’s maximum SID depth (SID), that is, exceeds the maximum number of labels the platform can push in to the outgoing packet.
    Note: The state is either valid or invalid.

State of a Candidate Path

The following describes the states of a candidate path.
  • Invalid: not eligible to participate in the best/active candidate path selection algorithm because of one of the reasons below.
    • all constituent SLs are invalid
    • Binding SID is not present
    • Binding SID is present but outside SRLB range
  • Valid: At least one SL is valid and has lost out to some other candidate path in the best / active candidate path selection algorithm.
  • Active: The candidate path is valid and is the winner in the best / active candidate path selection algorithm. The active candidate path is installed in the switch hardware and used for forwarding traffic.

State of an SR Policy

An SR policy is “valid” when at least one of its candidate paths is valid as described above. Otherwise, the SR policy is said to be “invalid”.

Resolution of an SL

An SL is resolved if the top label (first SID) can be resolved in the system Labeled FIB (LFIB) to yield a nexthop and outgoing interface(s). The other labels in the SID-List do not play a part in resolution.

Best Candidate Path (Active Candidate Path) Selection Algorithm

EOS overrides selection based on discriminator by retaining the current active candidate path even when current active path has a lower discriminator value. This reduces the active path flap when a new path is learnt of the same significance. The following is a summary of valid candidate paths ordering for a given policy.
  1. Candidate path with higher preference is chosen.
  2. Locally configured candidate path is chosen over BGP learnt path
  3. Lower originator is chosen.
    1. Lower AS number of Originator field is chosen
    2. Lower Node address of Originator field is chosen
  4. Current active candidate path is chosen

The following displays the reason for a path not getting selected as an active path for a specified policy.

switch# show traffic-engineering segment-routing policy endpoint <endpoint> color <color>

Binding SID

The use cases for Binding SID are the following.
  • Stitch together multiple domains
  • Stitch together different traffic tunnels
  • Overcome label stack imposition limitation in hardware.

BSID Conflict Handling

Examples

  1. (Between Policies): If the policy (E1, C1) becomes eligible to be active first then it would be installed in the LFIB and the policy (E2,C2) whose best path(CP1) is in conflict with the Policy (E1, C1) and will not become active.
    • Policy(E1, C1): CP1: Binding-SID 965536 (wins best path)
    • Policy(E2, C2): CP1: Binding-SID 965536 (wins best path)
    • CP2: Binding-SID 965537
  2. (with other Application): The SR-TE policies have the lowest preference when there is a conflict with any other application in EOS using the SRLB range. The candidate paths which have the binding-SID as that of an LFIB entry by another application (for example, static adjacency segment) will be kept as “invalid”.

In both the cases, when the conflict no longer exists, the candidate paths are re-evaluated and may become active.

BGP as a Source of Policies

SR Policies from a BGP peer (a controller, route reflector) is received for installation at the headend by EOS. It does not propagate the received policies to BGP peers nor does it originate SR Policies for transmission to BGP peers.

The following are supported over IPv4 or IPv6 peers which can be single hop or multi-hop iBGP or eBGP peers.

  1. SAFI 73 for AFI 1 and AFI 2: IPv4 and IPv6 policy endpoints, with the encoding defined in section 2.1 of Advertising Segment Routing Policies in BGP.
    Note: The nexthop address-family must match the AFI of the NLRI.
  2. Sub-TLVs of Tunnel Encapsulation TLV of type 15 (SR-TE Policy Type) of the Tunnel Encapsulation Path Attribute:
    1. Preference (Sub-TLV Type 12)
    2. Binding SID (Sub-TLV Type 13) of length 2 or 6 bytes
    3. Segment List (Sub-TLV Type 128). The following Segment List sub-TLVs are supported:
      1. Type 1 Segment (Sub-TLV type 1)
      2. Weight (Sub-TLV type 9)
    4. Explicit NULL Label Policy (Sub-TLV Type 14)
Note: All other sub-TLVs of the Tunnel Encapsulation TLV and Segment List sub-TLVs are ignored.

Route-Target and NO_ADVERTISE Community in SR-TE SAFI Updates

EOS implements the Acceptance and Usability checks as defined in sections 4.2.1 and 4.2.2 of the IETF draft Advertising Segment Routing Policies in BGP. However EOS skips matching the Route-Target with the router-ID of the headend if the SR-TE NLRI is tagged with NO_ADVERTISE community.

ECMP is not supported for SR-TE SAFI Paths

EOS does not support ECMP for BGP SR-TE SAFI. Only one best candidate path is chosen by BGP path selection and published to SR-TE Policy Agent for candidate path selection.
Note: ECMP of BGP next hops where each next hop resolves to an SR-TE policy is supported.

Path Selection within BGP

The IETF draft Advertising Segment Routing Policies in BGP supports passing multiple candidate paths from a single protocol source for an SR-TE policy path selection. Hence it includes a field distinguisher in the NLRI which can be unique for each controller to make BGP pass through the policies. However when multiple sources use the same distinguisher, BGP performs a path selection for the tuple: Endpoint, Color and Distinguisher. The best path for that tuple is published to the SR-TE Policy Agent for selecting an Active path. The best bgp-best-path selection applies to SR-TE SAFI as well.

Error Handling / Edge Cases

  • Weight 0: The IETF draft does not limit the range of SL weight to exclude weight 0. A SID-List with weight 0 is not used for forwarding so BGP module in EOS does not pass on SID-Lists with weight 0 to the SR-TE policy agent. Such SID-Lists will be visible in show bgp sr-te commands but not in show traffic-engineering segment-routing policy commands.
  • Empty SLs: Given the TLV encoding used to propagate SR Policies in BGP, it is possible to receive SID-Lists that have no SIDs (SID-Lists are empty). The BGP module in EOS does not pass such empty SID-Lists to SR-TE policy agent. Such SID-Lists will be visible in show bgp sr-te commands but not in show traffic-engineering segment-routing policy commands.
  • Non Type 1 segments: EOS supports only Type-1 segments. If a BGP update is received with a SID-List that has non Type-1 segments, the entire SID-List is ignored and BGP-4-SRTE_IGNORED_SEGMENT_LIST_UNSUPPORTED_SEGMENTS syslog is emitted. Such SID-Lists are not stored locally, and show bgp sr-te command does not display them.
    Note: The SID-Lists that are made up of all Type-1 segments are passed on to the SR-TE policy agent.

Steering Traffic into a Policy

Incoming label is BSID - “Labelled Steering”

At the headend when a packet is received with a label stack that has a BSID of an active CP of a valid SR Policy as the top label, the headend pops the label, and imposes the resolved label stack on the outgoing packet.

Example

Consider an SR Policy with an active candidate path with BSID 965536 and SL with label stack [965540, 900001, 900002]. Assume that 965540 is an IS-IS SR Adjacency SID. An incoming packet has label stack [965536, 100000] then the outgoing label stack is [900001, 900002, 100000].

Steering BGP learnt IP(v6) prefixes - “IP Steering”

Incoming label is BSID - “Labelled Steering”

At the headend, BGP IPv4 and IPv6 routes received with one or more extended color communities are recursively resolved through any active SR Policy that matches the BGP routes’ nexthop and color. When an IPv4 or IPv6 packet is received that is forwarded using this policy, the SL’s resolved label stack is imposed in the outgoing packet.

For BGP routes received with color community to be steered via an SR policy, the route’s nexthop must already be resolvable through IGP. If there is no resolving route in IGP, the route is considered unresolvable and will not be programmed in hardware even if there is a matching SR policy for the corresponding nexthop and color.

If there is no matching SR policy for the received BGP nexthop and color, the route will be resolved through the IGP route in IP RIB. If an active SR policy that matches the BGP nexthop and color gets instantiated at a later time, the BGP route will change from resolving through IGP to the new active SR policy.
Note: The recursion through SR policy is only applicable for BGP routes that are active in RIB.

Color only IP steering using CO bits

It is possible to relax the requirement of an exact match of the BGP route’s nexthop with the endpoint of the SR Policy using the “CO” (Color Only) bits in the color extended community. The “CO” bits are 2 reserved bits repurposed for color only steering as defined in section 3 of Advertising Segment Routing Policies in BGP. The exact match of the nexthop is done with the CO bits set to 00 or 11.

CO = 01 Steering: relaxes the nexthop to match the null endpoint of a policy. For a BGP route with nexthop N and color C, the following order is used for resolution. If there is no IGP route resolving the BGP nexthop, the route is not programmed in hardware.
  1. Active SR policy with endpoint N and color C
  2. Active SR policy with null endpoint (from the same AFI as the BGP route) and color C
  3. Active SR policy with null endpoint from any AFI and color C
  4. IGP route

CO = 10 Steering: in addition to the steps in CO = 01 steering, CO = 10 additionally relaxes the nexthop to match any endpoint. The following order is used for resolving a BGP route with nexthop N and color C. The behavior described is in accordance with section 8.8.1 of the IETF draft Segment Routing Policy for Traffic Engineering.

  1. Active SR policy with endpoint N and color C
  2. Active SR policy with null endpoint (from the same AFI as the BGP route) and color C
  3. Active SR policy with null endpoint from any AFI and color C
  4. Active SR policy for any endpoint from the same AFI as the BGP route and color C
  5. Active SR policy for any endpoint from any AFI and color C
  6. IGP route

ECMP of IPv4/IPv6 Prefixes that Resolve over SR-TE Policies

When multiple BGP paths of BGP unicast prefixes resolve through active SR policies form ECMP, the resulting FIB entry for the BGP route has an ECMP of segment list paths which is a union of all the segments-list entries present in each of the resolving SR policies for the BGP paths.

Example

The following table displays four paths for prefix 192.1.0.0/31, and each of the four paths resolves via SR-TE policies.

                                via 1.0.6.2, Ethernet6, label 2506 500

The traffic distribution honors the weights of the SID-Lists. In the example, each of the four SR Policies will get 25% of the total traffic meant for prefix 192.1.0.0/31. Within each policy, the distribution is based on the weights of the SID-Lists.

ECMP Group when some BGP unicast paths resolve over SR Policies and some via non SR Policy IGP paths

If some BGP paths resolve via SR Policy paths and some BGP paths resolve via non SR Policy IGP, then the ECMP group formed programmed as the active route in FIB, only considers the SR Policy paths. ECMP in the FIB is not formed between paths that resolve over SR Policy and paths that resolve via non SR Policy IGP routes. In the example above, if SR Policy with endpoint 1.0.6.2 and color 4000 becomes inactive or is removed, the FIB path for 192.1.0.0/31 resolves via 3 SR Policies as shown below.
B I    192.1.0.0/31 [200/0] via SR-TE Policy 1.0.4.2, color 3000
                             via SR-TE tunnel index 6, weight 1
                                via 1.0.4.2, Ethernet1, label 2505 500

                             via SR-TE tunnel index 1, weight 1
                                via 1.0.0.2, Ethernet2, label 2500 500

                                via 1.0.2.2, Ethernet3, label 2502 500
Note: show ip bgp still shows a 4-way ECMP. The FIB paths switch to resolving via the (non SR Policy) IGP paths when there are no BGP paths in the ECMP group that resolve via an SR Policy.

UCMP of IPv4/IPv6 prefixes using LinkBandwidth (LBW) Extended Community that resolve over SR-TE policies not supported

When multiple BGP paths of BGP unicast prefixes resolve through active SR policies form ECMP, and the unicast paths also contain the LBW extended community, EOS does not form UCMP amongst the unicast paths. Only ECMP is formed at the unicast prefix level. The LBW is ignored the behavior is identical to the behavior explained in the previous section.

Resolution of BGP unicast prefixes that resolve over other BGP unicast prefixes resolved via SR Policies

A BGP unicast prefix P1, that is recursively resolved via another BGP prefix P2, such that P2 resolves via an SR Policy, then in the FIB, P1 is programmed with the resolved nexthop pointing to the non SR Policy resolution of P2. P1 does not use P2s SR Policy for forwarding.

Explicit Null Label Imposition

When the address family of the BGP unicast prefix is not the same as the address family of the endpoint of the SR Policy that the unicast prefixes resolves via, an explicit null label is automatically imposed in the outgoing label stack.

Example

If an IPv4 unicast prefix P1 resolves over a policy whose endpoint EP1 is an IPv6 address (this can happen due to color only CO=01/10 steering with P1 having an IPv4 nexthop) and the SR Policy had a SID-List whose resolved label stack is [1001, 1002, 1003], the outgoing packet is imposed with [1001, 1002, 1003, 2] where 0 is the IPv4 explicit null label.

If an IPv6 prefix P2, resolves over a policy whose endpoint EP2 is an IPv4 address (this can happen with color only CO=01/10 steering with P2 having a IPv6 nexthop) and the SR Policy had a SID-List whose resolved label stack is [1001, 1002, 1003], the outgoing packet is imposed with [1001, 1002, 1003, 2] where 2 is the IPv6 explicit null label.

The following table lists the configurations which result in having explicit-null label in the resolved label stack.

Traffic Accounting

All egress tunnel counters (MPLS/GRE/MPLSoGRE using SR-TE/Nexthop-group/BGP-LU tunnel types) share the same hardware resource.
  • 7280E/7500E systems: Up to 16k tunnels
  • 7280R/7500R systems: Up to 8k tunnels
Tunnel counters are allocated on a first-come, first-served basis. Configurations using GRE/MPLSoGRE, GRE, and MPLS further limit a maximum of 4k countable egress MPLS tunnels on 7280R/7500R.

FEC Optimizations

The hardware FEC usage could be reduced as the underlying FEC is shared among different routes.
  • Programming of the active candidate path of an SR-TE policy in hardware is shared between the BSID route and IP steering route.
  • If all of the following conditions are met, ISIS-SR MPLS routes and tunnel entries directly point to the next hop FEC generated by the routing agent (IGP FEC).
    • All the next hops of the MPLS route either point to pop or forward (i.e. swapping to the same label) label action.
    • The switch is either a 7280 or a 7500 platform.
  • The corresponding SR-TE policy BSID routes (and corresponding Segment List tunnels) that resolve over ISIS-SR MPLS routes, will directly point to the IGP FEC.

Configuring SR-TE

The following commands start the SrTePolicy agent and enter the switch into the Traffic Engineering configuration sub-mode.
switch(config)# router traffic-engineering
switch(config-te)# segment-routing
Note: The agent must be running even if the only source of policies is BGP.
Static Policy Configuration
The following commands set the policy using endpoint and color value, and define the BSID for the policy.
switch(config-te-sr)# policy endpoint v4Address|v6Address color color-value
switch(config-te-sr-policy)# binding-sid mpls-label
switch(config-te-sr-policy)# path-group preference value
The following commands enter the policy path configuration sub mode, and adds a segment list to the candidate path.
switch(config-te-sr-policy)# path-group preference value
switch(config-te-sr-policy-path)# segment-list label-stack label1 label2 … weight value
Note: The default weight value is 1. Adding weight is optional. Repear the configuration statement for multiple segment lists per candidate path.
The following commands configures a null label policy.
switch(config-te-sr-policy-path)# explicit-null [none|ipv4|ipv6|both]
Note: The null label policy configuration is optional.

BGP configuration for SR-TE SAFI

The following commands configures a BGP router to activate a neighbor to negotiate and accept SR-TE address-family with this peer.

PBR Policies

Policy-Based Routing (PBR) allows the operator to specify the next hop for selected incoming packets on an L3 interface, overriding the routing table. Incoming packets are filtered through a policy map referencing one or more ACLs, and matching packets are routed to the next hop specified.

A PBR policy map is composed of one or more classes and can include next-hop information for each class. It can also include single-line raw match statements, which have the appearance and function of a single line from an ACL. Each class contains an eponymous class map. Class maps are user-created, can be edited or deleted, filter traffic using IPv4 ACLs, and are listed in running-config.

These sections describe PBR policy configuration procedures:

Traffic Management Configuration Arad Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane, or to L3 interfaces for Policy-Based Routing (PBR). Policy maps contain classes, which are composed of class maps and traffic resolution commands.

Traffic Management Conceptual Overview describes traffic policies.

Configuring Control Plane Traffic PoliciesArad Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in class (policy-map (control-plane) Arad). Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Policy maps are modified in policy-map configuration mode. The policy-map type copp command enters policy-map configuration mode.

Example

This command enters policy-map configuration mode for editing copp-system-policy.
switch(config)# policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

The class (policy-map (control-plane) Arad) command enters policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

This command enters policy-map-class configuration mode for the copp-system-lacp static class.
switch(config-pmap-copp-system-policy)# class copp-system-lacp
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#

Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 kilobits per seconds (kbps) for traffic filtered by the copp-system-lacp class map:
switch(config-pmap-c-copp-system-policy-copp-system-lacp)# bandwidth kbps 2000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)# shape kbps 4000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-copp-system-lacp)# exit
switch(config-pmap-copp-system-policy)# show pending
policy-map type copp copp-system-policy
  class copp-system-bpdu

  class copp-system-lldp

  class copp-system-lacp
    shape kbps 4000
    bandwidth kbps 2000

  class copp-system-l3ttl1

  class copp-system-l3slowpath


switch(config-pmap-copp-system-policy)# exit
switch(config)#

Applying Policy Maps to the Control Plane

The copp-system-policy policy map is always applied to the control plane. No commands are available to add or remove this assignment.

Displaying Policy Maps

The show policy-map interface type qos command displays the configured values of the policy maps classes and the number of packets filtered and dropped as a result of the class maps.

Example
These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config)# show policy-map copp copp-system-policy
Service-policy input: copp-system-policy
  Hardware programming status: InProgress

  Class-map: copp-system-mlag (match-any)
       shape : 10000001 kbps
       bandwidth : 10000001 kbps
      Out Packets : 0
      Drop Packets : 0

  Class-map: copp-system-bpdu (match-any)
       shape : 2604 kbps
       bandwidth : 1302 kbps
      Out Packets : 0
      Drop Packets : 0

  Class-map: copp-system-lacp (match-any)
       shape : 4230 kbps
       bandwidth : 2115 kbps
      Out Packets : 0
      Drop Packets : 0

switch(config)#

switch(config-pmap-c-copp-system-policy-copp-system-lacp)# exit

Configuring QoS Traffic Policies Arad Platform Switches

QoS traffic policies are implemented by creating class maps and policy maps, then applying the policy maps to Ethernet and port channel interfaces.

Creating Class Maps

QoS traffic policies utilize dynamic class maps that are created and modified in class-map configuration mode. The class-map type qos command enters class-map configuration mode.

Example

This command enters class-map configuration mode to create QoS class map named Q-CMap_1.
switch(config)# class-map type qos match-any Q-CMap_1
switch(config-cmap-Q-CMap_1)#

A class map contains one IPv4 access control list (ACL). The match ip access-group command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

This command adds the IPv4 ACL named ACL_1 to the class map.
switch(config-cmap-Q-CMap_1)# match ip access-group ACL_1
switch(config-cmap-Q-CMap_1)#

Class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting class-map configuration mode.
switch(config-cmap-Q-CMap_1)# show active
switch(config-cmap-Q-CMap_1)# show pending
class-map type qos match-any Q-CMap_1
   match ip access-group ACL_1

switch(config-cmap-Q-CMap_1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

This command exits class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-CP-CMAP_1)# exit
switch(config)# show class-map type control-plane CP-CMAP_1
  Class-map: CP-CMAP_1 (match-any)
    Match: ip access-group name ACLv4_1
switch(config)#

Creating Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type quality-of-service command enters policy-map configuration mode.

Example

This command places the switch in policy-map configuration mode and creates a QoS policy map named Q-PMAP_1.
switch(config)# policy-map type quality-of-service Q-PMAP_1
switch(config-pmap-Q-PMAP_1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; traffic resolution commands are added or edited in policy-map-class configuration mode. The below command adds a class to the configuration mode policy map and places the switch in policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

This command adds the Q-CMap_1 class to the Q-PMAP_1 policy map and places the switch in policy-map-class configuration mode.
switch(config-pmap-Q-PMAP_1)# class Q-CMap_1
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#
The set cos commands configure traffic resolution methods for data that passes the class map:
  • set cos sets the Layer 2 CoS field.
  • set dscp sets the DSCP value in the ToS byte.
  • set traffic class specifies a traffic class queue.

Example

These commands configure the policy map to set the CoS field 7 on packets filtered by the class map, then assigns those packets to traffic class 4.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# set cos 7
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# set traffic-class 4
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active and show pending commands display the saved and modified policy map versions, respectively.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode to save the altered policy map to running-config.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# exit
switch(config-pmap-Q-PMAP_1)# show pending
policy-map type quality-of-service Q-PMAP_1
  class Q-CMap_1
    set cos 7
    set traffic-class 4

  class class-default

switch(config-pmap-Q-PMAP_1)# exit
switch(config)#

The last class in all QoS policy maps is class-default. The class-default class map matches all traffic except IPv4 or IPv6 traffic and provides no traffic resolution commands. The class-default class map is not editable; traffic resolution commands can be added to the class-default class.

To modify traffic resolution commands for the class-default class, enter policy-map-class configuration mode for the class, then enter the desired set commands.

Example

These commands enter policy-map-class configuration mode for class-default, configures the stream to enter traffic class 2, and saves the altered policy map to running-config.
switch(config)# policy-map type quality-of-service Q-PMap_1
switch(config-pmap-Q-PMap_1)# class class-default
switch(config-pmap-c-Q-PMap_1-class-default)# set traffic-class 2
switch(config-pmap-c-Q-PMap_1-class-default)# exit
switch(config-pmap-Q-PMap_1)# exit
switch(config)# show policy-map type qos Q-PMap_1
Service-policy Q-PMap_1

  Class-map: Q-CMap_1 (match-any)
    Match: ipv6 access-group name ACLv6_1
       set cos 7
       set traffic-class 4

  Class-map: class-default (match-any)
       set traffic-class 2

switch(config)#

Applying Policy Maps to an Interface

The service-policy type qos (Interface mode) command applies a specified policy map to the configuration mode interface.

These commands apply PMAP-1 policy map to interfaceEthernet 8.
switch(config)# interface ethernet 8
switch(config-if-Et8)# show active
switch(config-if-Et8)# service-policy input PMAP-1
switch(config-if-Et8)# show active
interface Ethernet8
   service-policy type qos input PMAP-1
switch(config-if-Et8)#

Configuring PBR Policies Arad Platform Switches

Policy-Based Routing (PBR) is implemented by creating class maps and policy maps, then applying the policy maps to Ethernet interfaces, port channel interfaces or switch virtual interfaces (SVIs).

Creating PBR Class Maps

PBR policies utilize class maps that are created and modified in the class-map configuration mode. The class-map type pbr command enters the class-map configuration mode.

Example

This command enters the class-map configuration mode to create a PBR class map named CMAP1.
switch(config)# class-map type pbr match-any CMAP1
switch(config-cmap-PBR-CMAP1)#
A class map contains one or more access control lists (ACLs). The match (policy-map (pbr)) command assigns an ACL to the class map. Subsequent match commands add additional ACLs to the class map. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded; if a class map includes ACLs with deny rules, the configuration reverts to its previous state.

Example

This command adds the ACL named ACL1 to the class map.
switch(config-cmap-PBR-CMAP1)# match ip access-group ACL1
switch(config-cmap-PBR-CMAP1)#

The class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map.

The show active command indicates that the configuration mode class map is not stored in running-config. 
switch(config-cmap-PBR-CMAP1)# show active
switch(config-cmap-PBR-CMAP1)#

The exit command returns the switch to the global configuration mode and saves pending class map changes. The abort command returns the switch to the global configuration mode and discards pending changes.

Example

This command exits class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-PBR-CMAP1)# exit
switch(config)# show class-map type pbr CMAP1
class-map type pbr match-any CMAP1
   10 match ip access-group ACL1
switch(config)#

Creating PBR Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type pbr command enters the policy-map configuration mode.

Example

This command enters the policy-map configuration mode for creating a PBR policy map named PMAP1.
switch(config)# policy-map type pbr PMAP1
switch(config-pmap-PMAP1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; next-hop commands are added or edited in the policy-map-class configuration mode. The class (policy-map (pbr)) command adds a class to the configuration mode policy map and places the switch in the policy-map-class configuration mode, where next-hop commands are added to the class.

Example
  • This command adds the CMAP1 class to the policy map and places the switch into the policy-map-class configuration mode.
    switch(config-pmap-PMAP1)# class CMAP1
switch(config-pmap-c-PMAP1-CMAP1)#

    The set nexthop (policy-map-class pbr) command configures the next hop for data that passes the class map.

  • This command configures the policy map to set the next hop to 10.12.0.5 on packets filtered by the class map.
    switch(config-pmap-c-PMAP1-CMAP1)# set nexthop 10.12.0.5
switch(config-pmap-c-PMAP1-CMAP1)#

    The set nexthop-group (policy-map-class(pbr) Arad) command configures a nexthop group as the next hop for data that passes the class map.

  • These commands configure the policy map PMAP1 to set the next hop to a nexthop group named GROUP1 for traffic defined by class map CMAP1. 
    switch(config)# policy-map type pbr PMAP1
switch(config-pmap-PMAP1)# class CMAP1
switch(config-pmap-c-PMAP1-CMAP1)# set nexthop-group GROUP1
switch(config-pmap-c-PMAP1-CMAP1)#

    The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the currently saved map version.

  • These commands exits the policy-map-class configuration mode, then exits the policy-map configuration mode to save the altered policy map to running-config.
    switch(config-pmap-c-PMAP1-CMAP1)# exit
switch(config-pmap-PMAP1)# exit
switch(config)#

Applying a PBR Policy Map to an Interface

The service-policy type pbr (Interface mode) command applies the specified PBR policy map to the configuration mode interface. Only one PBR service policy is supported per interface.

These commands apply the PMAP1 PBR policy map to interface ethernet 8.
switch(config)# interface ethernet 8
switch(config-if-Et8)# service-policy type pbr input PMAP1
switch(config-if-Et8)#

Hardware Decapsulation

When hardware decapsulation takes place, PBR policy maps on Arad platform switches match on outer packet headers (i.e., they match based on the attributes of the packet before it is decapsulated).

Traffic Management Configuration FM6000 Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane or an interface. Policy maps contain classes, which are composed of class maps and traffic resolution commands. Traffic Management Conceptual Overview describes traffic policies.

FM6000 platform switches support the following traffic policies:
  • Control plane policies manage control plane traffic.
  • QoS traffic policies manage traffic on Ethernet and port channel interfaces.
These sections describe the construction and application of policy maps on FM6000 platform switches:

Configuring Control Plane Traffic PoliciesFM6000 Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: FM6000 Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Table 3. Copp-system-policy Default Classes: FM6000 Platform Switches
Class Name shape (pps) bandwidth (pps)
copp-system-arp 10000 1000
copp-system-default 8000 1000
copp-system-ipmcrsvd 10000 1000
copp-system-ipmcmiss 10000 1000
copp-system-igmp 10000 1000
copp-system-l2rsvd 10000 10000

copp-system-pim-ptp 10000 1000
copp-system-ospf-isis 10000 1000
copp-system-selfip 5000 5000
copp-system-selfip-tc6to7 5000 5000
copp-system-sflow 25000 1000

Policy maps are modified in the policy-map configuration mode. The policy-map type copp command enters the policy-map configuration mode.

Example

This command enters the policy-map configuration mode for editing copp-system-policy.
switch(config)# policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

The class (policy-map (control-plane) FM6000) command enters the policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

This command enters the policy-map-class configuration mode for the copp-system-arp static class.
switch(config-pmap-copp-system-policy)# class copp-system-arp
switch(config-pmap-c-copp-system-policy-copp-system-arp)#
Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 packets per seconds (pps) for traffic filtered by the copp-system-arp class map:
switch(config-pmap-c-copp-system-policy-copp-system-arp)# bandwidth pps 2000
switch(config-pmap-c-copp-system-policy-copp-system-arp)# shape pps 4000
switch(config-pmap-c-copp-system-policy-copp-system-arp)#

The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

These commands exit the policy-map-class configuration mode, display the pending policy-map, then exits the policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)# exit
switch(config-pmap-copp-system-policy)# show pending
policy-map type copp copp-system-policy
  class CP-CMAP_1
    shape pps 4000
    bandwidth pps 2000

  class copp-system-bpdu

  class copp-system-lldp

  class copp-system-lacp

  class copp-system-arp



  class copp-system-arpresolver

  class copp-system-default

switch(config-pmap-copp-system-policy)#exit
switch(config)#

Applying Policy Maps to the Control Plane

The copp-system-policy policy map is always applied to the control plane. No commands are available to add or remove this assignment.

Configuring QoS Traffic Policies FM6000 Platform Switches

QoS traffic policies are implemented by creating class maps and policy maps, then applying the policy maps to Ethernet and port channel interfaces.

Creating Class Maps

QoS traffic policies utilize dynamic class maps that are created and modified in the class-map configuration mode. The class-map type qos command enters the class-map configuration mode.

Example

This command enters the class-map configuration mode to create QoS class map named Q-CMap_1.
switch(config)# class-map type qos match-any Q-CMap_1
switch(config-cmap-Q-CMap_1)#

A class map contains one IPv4 access control list (ACL). The match (class-map (qos) FM6000) command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

This command adds the IPv4 ACL named ACL_1 to the class map.
switch(config-cmap-Q-CMap_1)# match ip access-group ACL_1
switch(config-cmap-Q-CMap_1)#

The class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting the class-map configuration mode.
switch(config-cmap-Q-CMap_1)# show active
switch(config-cmap-Q-CMap_1)# show pending
class-map type qos match-any Q-CMap_1
   match ip access-group ACL_1

switch(config-cmap-Q-CMap_1)#

The exit command returns the switch to the global configuration mode and saves pending class map changes. The abort command returns the switch to the global configuration mode and discards pending changes.

Example

This command exits the class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-CP-CMAP_1)# exit
switch(config)# show class-map type control-plane CP-CMAP_1
  Class-map: CP-CMAP_1 (match-any)
    Match: ip access-group name ACLv4_1
switch(config)#

Creating Policy Maps

Policy maps are created and modified in the policy-map configuration mode. The policy-map type quality-of-service command enters the policy-map configuration mode.

Example

This command places the switch in the policy-map configuration mode and creates a QoS policy map named Q-PMAP_1.
switch(config)# policy-map type quality-of-service Q-PMAP_1
switch(config-pmap-Q-PMAP_1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; traffic resolution commands are added or edited in the policy-map-class configuration mode. The class (policy-map (qos) FM6000) command adds a class to the configuration mode policy map and places the switch in the policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

This command adds the Q-CMap_1 class to the Q-PMAP_1 policy map and places the switch in the policy-map-class configuration mode.
switch(config-pmap-Q-PMAP_1)# class Q-CMap_1
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#
set (policy-map-class (qos) FM6000) commands configure traffic resolution methods for data that passes the class map:
  • set cos sets the Layer 2 CoS field.
  • set dscp sets the DSCP value in the ToS byte.
  • set traffic class specifies a traffic class queue.

Example

These commands configure the policy map to set the CoS field 7 on packets filtered by the class map, then assigns those packets to traffic class 4.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# set cos 7
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# set traffic-class 4
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active and show pending commands display the saved and modified policy map versions, respectively.

Example

These commands exit the policy-map-class configuration mode, display the pending policy-map, then exits the policy-map configuration mode to save the altered policy map to running-config.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# exit
switch(config-pmap-Q-PMAP_1)# show pending
policy-map type quality-of-service Q-PMAP_1
  class Q-CMap_1
    set cos 7
    set traffic-class 4

  class class-default

switch(config-pmap-Q-PMAP_1)# exit
switch(config)#

The last class in all QoS policy maps is class-default. The class-default class map matches all traffic except IPv4 or IPv6 traffic and provides no traffic resolution commands. The class-default class map is not editable; traffic resolution commands can be added to the class-default class.

To modify traffic resolution commands for the class-default class, enter the policy-map-class configuration mode for the class, then enter the desired set commands.

Example

These commands enter the policy-map-class configuration mode for class-default, configures the stream to enter traffic class 2, and saves the altered policy map to running-config.
switch(config)# policy-map type quality-of-service Q-PMap_1
switch(config-pmap-Q-PMap_1) #class class-default
switch(config-pmap-c-Q-PMap_1-class-default)# set traffic-class 2
switch(config-pmap-c-Q-PMap_1-class-default)# exit
switch(config-pmap-Q-PMap_1)# exit
switch(config)# show policy-map type qos Q-PMap_1
Service-policy Q-PMap_1

  Class-map: Q-CMap_1 (match-any)
    Match: ipv6 access-group name ACLv6_1
       set cos 7
       set traffic-class 4

  Class-map: class-default (match-any)
       set traffic-class 2

switch(config)#

Applying Policy Maps to an Interface

The service-policy type qos (Interface mode) command applies a specified policy map to the configuration mode interface.

These commands apply PMAP-1 policy map to interface ethernet 8.
switch(config)# interface ethernet 8
switch(config-if-Et8)# show active
switch(config-if-Et8)# service-policy input PMAP-1
switch(config-if-Et8)# show active
interface Ethernet8
   service-policy type qos input PMAP-1
switch(config-if-Et8)#

Configuring PBR Policies FM6000 Platform Switches

Policy-Based Routing (PBR) is implemented by creating class maps and policy maps, then applying the policy maps to Ethernet interfaces, port channel interfaces or Switch Virtual Interfaces (SVIs).

Creating PBR Class Maps

PBR policies utilize class maps that are created and modified in the class-map configuration mode. The class-map type pbr command enters the class-map configuration mode.

Example

This command enters the class-map configuration mode to create a PBR class map named CMAP1.
switch(config)# class-map type pbr match-any CMAP1
switch(config-cmap-PBR-CMAP1)#

A class map contains one or more IPv4 access control lists (ACLs). The match (policy-map (pbr)) command assigns an ACL to the class map. Subsequent match commands add additional ACLs to the class map. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded; if a class map includes ACLs with deny rules, the configuration reverts to its previous state.

On FM6000 platform switches, counters are not supported, so a counters per-entry (ACL configuration modes) command in an ACL is ignored.

Example

This command adds the IPv4 ACL named ACL1 to the class map.
switch(config-cmap-PBR-CMAP1)# match ip access-group ACL1
switch(config-cmap-PBR-CMAP1)#

The class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map.

The show active command indicates that the configuration mode class map is not stored in running-config. 
switch(config-cmap-PBR-CMAP1)# show active
switch(config-cmap-PBR-CMAP1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

This command exits the class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-PBR-CMAP1)# exit
switch(config)# show class-map type pbr CMAP1
class-map type pbr match-any CMAP1
   10 match ip access-group ACL1
switch(config)#

Creating PBR Policy Maps

Policy maps are created and modified in the policy-map configuration mode. The policy-map type pbr command enters the policy-map configuration mode.

Example

This command enters the policy-map configuration mode for creating a PBR policy map named PMAP1.
switch(config)# policy-map type pbr PMAP1
switch(config-pmap-PMAP1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; next-hop commands are added or edited in the policy-map-class configuration mode. The class (policy-map (pbr)) command adds a class to the configuration mode policy map and places the switch in the policy-map-class configuration mode, where next-hop commands are added to the class.

Examples
  • This command adds the CMAP1 class to the policy map and places the switch in the policy-map-class configuration mode.
    switch(config-pmap-PMAP1)# class CMAP1
switch(config-pmap-c-PMAP1-CMAP1)#

    The set nexthop (policy-map-class pbr) command configures the next hop for data that passes the class map.

  • This command configures the policy map to set the next hop to 10.12.0.5 on packets filtered by the class map.
    switch(config-pmap-c-PMAP1-CMAP1)# set nexthop 10.12.0.5
switch(config-pmap-c-PMAP1-CMAP1)#

    The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the currently saved map version.

Example
These commands exits the policy-map-class configuration mode, then exits the policy-map configuration mode to save the altered policy map to running-config.
switch(config-pmap-c-PMAP1-CMAP1)# exit
switch(config-pmap-PMAP1)# exit
switch(config)#

Applying a PBR Policy Map to an Interface

The service-policy type pbr (Interface mode) command applies the specified PBR policy map to the configuration mode interface. Only one PBR service policy is supported per interface.

These commands apply the PMAP1 PBR policy map to interface ethernet 8.
switch(config)# interface ethernet 8
switch(config-if-Et8)# service-policy type pbr input PMAP1
switch(config-if-Et8)#

Hardware Decapsulation

When hardware decapsulation takes place, PBR policy maps on FM6000 platform switches match on outer packet headers (i.e., they match based on the attributes of the packet before it is decapsulated).

Traffic Management Configuration Petra Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane. Policy maps contain classes, which are composed of class maps and traffic resolution commands. QoS traffic policies are not supported on 7500 Series switches.

Traffic Management Conceptual Overview describes traffic policies.

Configuring Control Plane Traffic PoliciesPetra Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: Petra Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Table 4. copp-system-policy default classes: Petra Platform Switches

copp-system-lacp 2500 1250
copp-system-lldp 2500 250
copp-system-unicast-arp 2500 250

Policy maps are modified in the policy-map configuration mode. The policy-map type copp command enters the policy-map configuration mode.

Example
This command enters the policy-map configuration mode for editing copp-system-policy.
switch(config)# policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

The class (policy-map (control-plane) Petra) command enters the policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

  • This command enters the policy-map-class configuration mode for the copp-system-lldp static class.
    switch(config-pmap-copp-system-policy)# class copp-system-lldp
switch(config-pmap-c-copp-system-policy-copp-system-lldp)#
Two traffic resolution commands determine bandwidth parameters for class traffic:
Example
These commands configure a bandwidth range of 2000 to 4000 kilobits per seconds (kbps) for traffic filtered by the copp-system-arp class map:
switch(config-pmap-c-copp-system-policy-copp-system-lldp)# bandwidth kbps 2000
switch(config-pmap-c-copp-system-policy-copp-system-lldp)# shape kbps 4000
switch(config-pmap-c-copp-system-policy-copp-system-lldp)#

The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the configured policy map.

Petra platform switches do not support all discrete rate values. When a bandwidth or shape command specifies a value that is not supported, the switch converts the rate to the next highest discrete value that it supports. The show policy-map interface type qos command displays the converted rate and not the user configured rate.

Example
These commands exits the policy-map-class configuration mode, display the pending policy-map, then exits the policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-copp-system-lacp)# exit
switch(config-pmap-copp-system-policy)# show pending
policy-map type copp copp-system-policy
  class copp-system-bpdu

  class copp-system-lldp
    shape kbps 4000
    bandwidth kbps 2000

  class copp-system-lacp

switch(config-pmap-copp-system-policy)#exit
switch(config)#

Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Displaying Policy Maps

The show policy-map interface type qos command displays the traffic resolution rates of the policy maps classes and the number of packets filtered and dropped as a result of the class maps. The shape and bandwidth rates may differ from configured values, because the switch does not support all discrete rate values.

Example

These commands exits the policy-map-class configuration mode, display the pending policy-map, then exits the policy-map configuration mode, which saves the altered policy map to running-config.
switch(config)# show policy-map copp copp-system-policy
Service-policy input: copp-system-policy
  Hardware programming status: InProgress

  Class-map: copp-system-mlag (match-any)

Traffic Management Configuration Trident Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane or an interface. Policy maps contain classes, which are composed of class maps and traffic resolution commands. Traffic Management Conceptual Overview describes traffic policies.

Trident platform switches support the following traffic policies:
  • Control plane policies manage control plane traffic.
  • QoS traffic policies manage traffic on Ethernet and port channel interfaces.
These sections describe the construction and application of policy maps:

Configuring Control Plane Traffic PoliciesTrident Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by creating class maps and editing the policy map to include the new class maps.

Creating Class Maps

Control plane traffic policies utilize static and dynamic class maps. Static class maps are provided by the switch, are not editable, and cannot be deleted. Dynamic class maps are created and modified in the class-map configuration mode. The class-map type copp command enters the class-map configuration mode.

Example

This command enters the class-map configuration mode for creating or editing a control plane dynamic class map named CP-CMAP_1.
switch(config)# class-map type copp match-any CP-CMAP_1
switch(config-cmap-CP-CMAP_1)#

Class maps contain one IPv4 or IPv6 access control list (ACL). The match (class-map (control-plane) Trident) command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

This command assigns the IPv4 ACL named ACLv4_1 to the class map.
switch(config-cmap-CP-CMAP_1)# match ip access-group ACLv4_1
switch(config-cmap-CP-CMAP_1)#

The class-map configuration mode is a group-change mode. Changes are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting the class-map configuration mode.
switch(config-cmap-CP-CMAP_1)# show active
switch(config-cmap-CP-CMAP_1)# show pending
class-map type copp match-any CP-CMAP_1
   match ip access-group ACLv4_1

switch(config-cmap-CP-CMAP_1)#

The exit command returns the switch to the global configuration mode and saves pending class map changes. The abort command returns the switch to the global configuration mode and discards pending class map changes.

Example

This command exits the class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-CP-CMAP_1)# exit
switch(config)# show class-map type control-plane CP-CMAP_1
  Class-map: CP-CMAP_1 (match-any)
    Match: ip access-group name ACLv4_1
switch(config)#

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: Trident Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Table 5. copp-system-policy default classes: Trident Platform Switches

Policy maps are modified in the policy-map configuration mode. The policy-map type copp command enters the policy-map configuration mode.

Example

This command enters the policy-map configuration mode for editing copp-system-policy.
switch(config)#policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

Dynamic classes are inserted in front of the static classes. Classes automatically contain their eponymous class map; traffic resolution commands are created or edited in the policy-map-class configuration mode. The class (policy-map (control-plane) Trident) command adds a class to the policy map and places the switch in the policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

This command adds the CP-CMAP_1 class to the copp-system-policy policy map and places the switch in the policy-map-class configuration mode.
switch(config-pmap-copp-system-policy)#class CP-CMAP_1
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#
Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 packets per seconds (pps) for traffic filtered by the CP-CMAP_1 class map:
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)# bandwidth pps 2000
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)# shape pps 4000
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#

Example

The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

These commands exits the policy-map-class configuration mode, display the pending policy-map, then exits the policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)# exit
switch(config-pmap-copp-system-policy)# show pending

Example

To modify traffic resolution commands for a static class, enter the policy-map-class configuration mode for the class, then enter the desired bandwidth and shape commands.

Example

These commands enters the policy-map-class configuration mode for copp-system-bpdu class, change the bandwidth range for the class, then save the altered policy map to running-config.

Applying Policy Maps to the Control Plane

The copp-system-policy policy map is always applied to the control plane. No commands are available to add or remove this assignment.

Configuring QoS Traffic Policies Trident Platform Switches

QoS traffic policies are implemented by creating class maps and policy maps, then applying the policy maps to Ethernet and port channel interfaces.

Creating Class Maps

QoS traffic policies utilize dynamic class maps that are created and modified in the class-map configuration mode. The class-map type qos command enters the class-map configuration mode.

Example

This command enters the class-map configuration mode to create QoS class map named Q-CMap_1.
switch(config)# class-map type qos match-any Q-CMap_1
switch(config-cmap-Q-CMap_1)#

A class map contains one IPv4 or IPv6 Access Control List (ACL). The match (class-map (qos) Trident) command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

This command adds the IPv6 ACL named ACLv6_1 to the class map.
switch(config-cmap-Q-CMap_1)# match ipv6 access-group ACLv6_1
switch(config-cmap-Q-CMap_1)#

The class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting the class-map configuration mode.
switch(config-cmap-Q-CMap_1)# show active
switch(config-cmap-Q-CMap_1)# show pending
class-map type qos match-any Q-CMap_1
   match ipv6 access-group ACLv6_1

switch(config-cmap-Q-CMap_1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending class map changes.

Example

This command exits the class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-CP-CMAP_1)# exit
switch(config)# show class-map type control-plane CP-CMAP_1
  Class-map: CP-CMAP_1 (match-any)
    Match: ip access-group name ACLv4_1
switch(config)#

Creating Policy Maps

Policy maps are created and modified in the policy-map configuration mode. The policy-map type quality-of-service command enters the policy-map configuration mode.

Example

This command enters the policy-map configuration mode for creating a QoS policy map named Q-PMAP_1.
switch(config)# policy-map type quality-of-service Q-PMAP_1
switch(config-pmap-Q-PMAP_1)#

Policy maps are edited by adding or removing classes. A class automatically contains its eponymous class map; traffic resolution commands are added or edited in the policy-map-class configuration mode. The class (policy-map (qos) Trident) command adds a class to the configuration mode policy map and places the switch in the policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

This command adds the Q-CMap_1 class to the Q-PMAP_1 policy map and places the switch in the policy-map-class configuration mode.
switch(config-pmap-Q-PMAP_1)# class Q-CMap_1
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#
The set (policy-map-class (qos) Trident) command configures traffic resolution methods for data that passes the class map:
  • set cos sets the layer 2 CoS field.
  • set dscp sets the DSCP value in the ToS byte.
  • set traffic class specifies a traffic class queue.

Example

These commands configure the policy map to set CoS field 7 on packets filtered by the class map, then assigns those packets to traffic class 4.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# set cos 7
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# set traffic-class 4
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active and show pending commands display the saved and modified policy map versions, respectively.

Example

These commands exit the policy-map-class configuration mode, display the pending policy-map, then exits the policy-map configuration mode to save the altered policy map to running-config.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)# exit
switch(config-pmap-Q-PMAP_1)# show pending
policy-map type quality-of-service Q-PMAP_1
  class Q-CMap_1
    set cos 7
    set traffic-class 4

  class class-default

switch(config-pmap-Q-PMAP_1)# exit
switch(config)#

The last class in all QoS policy maps is class-default. The class-default class map matches all traffic except IPv4 or IPv6 traffic and provides no traffic resolution commands. The class-default class map is not editable; traffic resolution commands can be added to the class-default class.

To modify traffic resolution commands for the class-default class, enter the policy-map-class configuration mode for the class, then enter the desired set commands.

Example

These commands enters the policy-map-class configuration mode for class-default, configures the stream to enter traffic class 2, and saves the altered policy map to running-config.
switch(config)# policy-map type quality-of-service Q-PMap_1
switch(config-pmap-Q-PMap_1)# class class-default
switch(config-pmap-c-Q-PMap_1-class-default)# set traffic-class 2
switch(config-pmap-c-Q-PMap_1-class-default)# exit
switch(config-pmap-Q-PMap_1)# exit
switch(config)# show policy-map type qos Q-PMap_1
Service-policy Q-PMap_1

  Class-map: Q-CMap_1 (match-any)
    Match: ipv6 access-group name ACLv6_1
       set cos 7
       set traffic-class 4

  Class-map: class-default (match-any)
       set traffic-class 2

switch(config)#

Applying Policy Maps to an Interface

The service-policy type qos (Interface mode) command applies a specified policy map to the configuration mode interface.

Example

These commands apply PMAP-1 policy map to interface ethernet 8.
switch(config)# interface ethernet 8
switch(config-if-Et8)# show active
switch(config-if-Et8)# service-policy input PMAP-1
switch(config-if-Et8)# show active
interface Ethernet8
   service-policy type qos input PMAP-1
switch(config-if-Et8)#

Configuring PBR Policies Trident Platform Switches

Policy-Based Routing (PBR) is implemented by creating class maps and policy maps, then applying the policy maps to Ethernet interfaces, port channel interfaces or Switch Virtual Interfaces (SVIs).

Creating PBR Class Maps

PBR policies utilize class maps that are created and modified in the class-map configuration mode. The class-map type pbr command enters the class-map configuration mode.

Example

This command enters the class-map configuration mode to create a PBR class map named CMAP1.
switch(config)# class-map type pbr match-any CMAP1
switch(config-cmap-PBR-CMAP1)#

A class map contains one or more Access Control Lists (ACLs). The match (policy-map (pbr)) command assigns an ACL to the class map. Subsequent match commands add additional ACLs to the class map. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded; if a class map includes ACLs with deny rules, the configuration reverts to its previous state.

Examples

  • This command adds the ACL named ACL1 to the class map.
    switch(config-cmap-PBR-CMAP1)# match ip access-group ACL1
switch(config-cmap-PBR-CMAP1)#

The class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map.

  • The show active command indicates that the configuration mode class map is not stored in running-config. 
    switch(config-cmap-PBR-CMAP1)# show active
switch(config-cmap-PBR-CMAP1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

This command exits the class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-PBR-CMAP1)# exit
switch(config)# show class-map type pbr CMAP1
class-map type pbr match-any CMAP1
   10 match ip access-group ACL1
switch(config)#

Creating PBR Policy Maps

Policy maps are created and modified in the policy-map configuration mode. The policy-map type pbr command enters policy-map configuration mode.

Example

This command enters the policy-map configuration mode for creating a PBR policy map named PMAP1.
switch(config)# policy-map type pbr PMAP1
switch(config-pmap-PMAP1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; next-hop commands are added or edited in the policy-map-class configuration mode. The class (policy-map (pbr)) command adds a class to the configuration mode policy map and places the switch in the policy-map-class configuration mode, where next-hop commands are added to the class.

Example
  • This command adds the CMAP1 class to the policy map and places the switch in the policy-map-class configuration mode.
    switch(config-pmap-PMAP1)# class CMAP1
switch(config-pmap-c-PMAP1-CMAP1)#
  • The set nexthop (policy-map-class pbr) command configures the next hop for data that passes the class map.This command configures the policy map to set the next hop to 10.12.0.5 on packets filtered by the class map.
    switch(config-pmap-c-PMAP1-CMAP1)# set nexthop 10.12.0.5
switch(config-pmap-c-PMAP1-CMAP1)#
  • The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the currently saved map version.These commands exits the policy-map-class configuration mode, then exits the policy-map configuration mode to save the altered policy map to running-config.
    switch(config-pmap-c-PMAP1-CMAP1)# exit
switch(config-pmap-PMAP1)# exit
switch(config)#

Applying a PBR Policy Map to an Interface

The service-policy type pbr (Interface mode) command applies the specified PBR policy map to the configuration mode interface. Only one PBR service policy is supported per interface.
  • These commands apply the PMAP1 PBR policy map to interface ethernet 8.
    switch(config)# interface ethernet 8
switch(config-if-Et8)# service-policy type pbr input PMAP1
switch(config-if-Et8)#

Hardware Decapsulation

When hardware decapsulation takes place, PBR policy maps on Trident platform switches match on inner packet headers (i.e., they match based on the attributes of the decapsulated packet).

Traffic Management Configuration Trident II Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane or an interface. Policy maps contain classes, which are composed of class maps and traffic resolution commands. Traffic Management Conceptual Overview describes traffic policies.

Trident platform switches support the following traffic policies:
  • Control plane policies manage control plane traffic.
  • QoS traffic policies manage traffic on Ethernet and port channel interfaces.

Configuring Control Plane Traffic PoliciesTrident II Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: Trident II Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Table 6. copp-system-policy default classes: Trident II Platform Switches
Class Name shape (pps) bandwidth (pps)
copp-system-acllog 1000 10000

copp-system-tc3to5 1000 10000
copp-system-tc6to7 1000 10000
copp-system-urm 1000 10000

Policy maps are modified in the policy-map configuration mode. The policy-map type copp command enters the policy-map configuration mode.

Example

This command enters the policy-map configuration mode for editing copp-system-policy.
switch(config)# policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

Example

The class (policy-map (control-plane) Trident II) command enters the policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

This command enters the policy-map-class configuration mode for the copp-system-lacp static class.
switch(config-pmap-copp-system-policy)# class copp-system-lacp
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#
Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 packets per seconds (pps) for traffic filtered by the copp-system-lacp class map:
switch(config-pmap-c-copp-system-policy-copp-system-lacp)# bandwidth pps 2000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)# shape pps 4000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#

Example

The policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

These commands exits the policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-copp-system-lacp)# exit
switch(config-pmap-copp-system-policy)# show pending

Guidelines

Petra does not support all discrete rate values. When a specified discrete value is not supported, the switch converts the rate to the next highest discrete value that it supports. The show command displays the converted rate and not the user-configured rate.

Example

These commands configure a minimum bandwidth of 500 kbps for data traffic specified by the class map copp-system-lldp of the default control-plane policy map. Because the switch does not support the discrete value of 500 kbps, it converts the bandwidth up to 651 kbps.

class (policy-map (control-plane) Arad)

The class command places the switch in policy-map-class (control plane) configuration mode, which is a group change mode for changing bandwidth and shape parameters associated with a specified class. All changes in a group change mode edit session are pending until the end of the session.

A policy map is an ordered list of classes. The control plane policy map contains 20 static classes. Each class contains an eponymous class map and may contain bandwidth and shape commands.
  • The class map identifies a data stream.
  • bandwidth command defines the streams minimum transmission rate through the control plane.
  • shape command defines the streams maximum transmission rate through the control plane.

Static class maps identify a data stream by definition. Each data packet is managed by commands of the first class whose map matches the packets content. Dynamic classes are not supported for control plane policing on Arad platform switches.

Each class corresponds to a transmission queue. Queue scheduling is round-robin until bandwidth rate for a queue is exceeded. Scheduling becomes strict-priority with CPU queue number determining priority until the shape rate is reached. Packets are dropped after the shape rate is exceeded.

The exit command returns the switch to policy-map configuration mode. Saving policy-map-class changes also require an exit from policy-map mode, which saves pending policy-map-class and policy-map changes to running-config and returns the switch to the global configuration mode. The abort command discards pending changes, returning the switch to the global configuration mode.

The no class and default class commands remove policy-map-class commands for the specified class assignment from the policy map.

class (policy-map (control-plane) Trident)

The class command places the switch in policy-map-class (control plane) configuration mode, which is a group change mode for changing bandwidth and shape parameters associated with a specified class. The command adds the specified class to the policy map if it was not previously included. All changes in a group change mode edit session are pending until the end of the session.

A policy map is an ordered list of classes. The control plane policy map contains 18 static classes and up to 30 dynamic classes. Dynamic classes contain an eponymous class map. All classes may contain bandwidth and shape commands.
  • The class map identifies a data stream.
  • bandwidth command defines the streams minimum transmission rate through the control plane.
  • shape command defines the streams maximum transmission rate through the control plane.

Dynamic class maps identify a data stream with an ACL assigned by match (class-map (control-plane) Trident). Static class maps identify a data stream by definition. Each data packet is managed by commands of the first class whose map matches the packets content.

Static classes are provided with the switch and cannot be removed from the policy map or modified by the class command. Dynamic classes are user defined and added to the policy map by this command. Dynamic classes are always placed in front of the static classes. Bandwidth and shape parameters are editable for all classes.

Each class corresponds to a transmission queue. Queue scheduling is round-robin until bandwidth rate for a queue is exceeded. Scheduling becomes strict-priority with CPU queue number determining priority until the shape rate is reached. Packets are dropped after the shape rate is exceeded.

The exit command returns the switch to policy-map configuration mode. Saving the policy-map-class changes also require an exit from policy-map mode, which saves the pending policy-map-class and policy-map changes to running-config and returns the switch to the global configuration mode. The abort command discards pending changes, returning the switch to the global configuration mode.

class (policy-map (pbr)

The class (policy-map (pbr) command places the switch in policy-map-class (pbr) configuration mode, which is a group change mode that modifies the specified class of the configuration mode Policy-Based Routing (PBR) policy map. The command adds the class to the policy map if it was not previously included in the policy map. All changes in a group change mode edit session are pending until the mode is exited, and can be canceled by using the abort command.

A PBR policy map is an ordered list of classes. Each class contains an eponymous class map and can contain set commands to specify next hop. Classes without set commands translate to no action being performed on that class of packets.
  • The class map identifies a data stream through ACLs. Class maps are configured in the class-map (pbr) configuration mode.
  • Set commands can be used to specify the next hop for a given class. Set commands are configured in policy-map-class (pbr) configuration mode.

PBR policy maps can also contain one or more raw match statements which filter incoming traffic without using ACLs. Data packets are managed by commands of the first class or raw match statement matching the packets contents.

The exit command returns the switch to the policy-map (pbr) configuration mode. However, saving the policy-map-class changes also requires an exit from policy-map (pbr) configuration mode. This saves all the pending policy map and policy-map-class changes to running-config and returns the switch to the global configuration mode. The abort command discards pending changes, returning the switch to the global configuration mode.

The no class and default class commands remove the class assignment from the configuration mode policy map by deleting the corresponding class configuration from running-config.

Command Mode

switch(config-pmap-PMAP-1)# class CMAP-1
switch(config-pmap-c-PMAP-1-CMAP-1)#

class (policy-map (qos) Trident)

The class command places the switch in policy-map-class (qos) configuration mode, which is a group change mode that modifies the specified class of the configuration mode policy map. The command adds the class to the policy map if it was not previously included in the policy map. All changes in a group change mode edit session are pending until the end of the session.

A policy map is an ordered list of classes. Each class contains an eponymous class map and at least one set command:
  • The class map identifies a data stream through an ACL. Class maps are configured in class-map (qos) configuration mode.
  • Set commands either modify a packets content (CoS or DSCP fields) or assigns it to a traffic class queue. Set commands are configured in policy-map-class (qos) configuration mode.

    Data packets are managed by commands of the first class whose map matches the packets content.

The exit command returns the switch to policy-map configuration mode. However, saving policy-map-class changes also require an exit from policy-map mode. This saves all the pending policy map and policy-map-class changes to running-config and returns the switch to the global configuration mode. The abort command discards pending changes, returning the switch to the global configuration mode.

The no class and default class commands remove the class assignment from the configuration mode policy map by deleting the corresponding class configuration from running-config.

class-map type copp

The class-map type copp command places the switch in Class-Map (control plane) configuration mode, which is a group change mode that modifies a control-plane dynamic class map. A dynamic class map is a data structure that uses Access Control Lists (ACLs) to define a data stream by specifying characteristics of data packets that comprise that stream. Control-plane policy maps use class maps to specify which control plane traffic is controlled by policy map criteria.

The exit command saves pending class map changes to running-config and returns the switch to the global configuration mode. Class map changes are also saved by entering a different configuration mode. The abort command discards pending changes and returns the switch to the global configuration mode.

The no class-map type copp and default class-map type copp commands delete the specified class map by removing the corresponding class-map type copp command and its associated configuration.

class-map type pbr

The class-map type pbr command places the switch in the class-map (pbr) configuration mode for the specified class map, and creates the class map if one does not already exist. The class-map (PBR) configuration mode is a group change mode that modifies a class map for Policy-Based Routing (PBR). PBR class maps contain one or more match statements which filter incoming traffic using ACLs. PBRs can then use these class maps to set next-hop IP addresses for the traffic that matches them. (Classes without set commands translate to no action being performed on that class of packets.)

The exit command saves pending class map changes to running-config, then returns the switch to the global configuration mode. Class map changes are also saved by directly entering a different configuration mode. The abort command discards pending changes and returns the switch to the global configuration mode.

The no class-map type pbr and default class-map type pbr commands delete the specified class map by removing the corresponding class-map type pbr command and its associated configuration.

class-map type qos

The class-map type qos command places the switch in the class-map (QoS) configuration mode, which is a group change mode that modifies a QoS dynamic class map. A dynamic class map is a data structure that uses Access Control Lists (ACLs) to define a data stream by specifying characteristics of data packets that comprise that stream. QoS policy maps use class maps to specify the traffic (to which the policy map is assigned) that is transformed by policy map criteria.

The exit command saves pending class map changes to running-config, then returns the switch to the global configuration mode. Class map changes are also saved by entering a different configuration mode. The abort command discards pending changes and returns the switch to the global configuration mode.

The no class-map type qos and default class-map type qos commands delete the specified class map by removing the corresponding class-map type qos command and its associated configuration. The class-map and class-map type qos commands are equivalent.

policy-map type copp

The policy-map type copp command places the switch in the policy-map (control plane) configuration mode, which is a group change mode that modifies a control-plane policy map. A policy map is a data structure that consists of class maps that identify a specific data stream and specify bandwidth and shaping parameters that controls its transmission. Control plane policy maps are applied to the control plane to manage traffic.

The copp-system-policy policy map is supplied with the switch and is always applied to the control plane. The copp-system-policy is the only valid control plane policy map.

The exit command saves pending policy map changes to running-config and returns the switch to the global configuration mode. Policy map changes are also saved by entering a different configuration mode. The abort command discards pending changes, returning the switch to the global configuration mode.

The no policy-map type copp and default policy-map type copp commands delete the specified policy map by removing the corresponding policy-map type copp command and its associated configuration.

The policy-map type pbr command places the switch in policy-map (pbr) configuration mode, which is a group change mode that modifies a Policy-Based Routing (PBR) policy map. The command also creates the specified policy map if it does not already exist. A PBR policy map is a data structure that consists of class maps that identify specific packets and the next hops for those packets. Policy maps are applied to Ethernet or port channel interfaces to manage traffic.

The exit command saves pending policy map changes to running-config and returns the switch to the global configuration mode. Policy map changes are also saved by entering a different configuration mode. The abort command discards pending changes, returning the switch to the global configuration mode.

The no policy-map type pbr and default policy-map type pbr commands delete the specified policy map by removing the corresponding policy-map type pbr command and its associated configuration.

policy-map type quality-of-service

The policy-map type quality-of-service command places the switch in the policy-map (QoS) configuration mode, which is a group change mode that modifies a QoS policy map. A policy map is a data structure that consists of class maps that identify a specific data stream and shaping parameters that controls its transmission. Policy maps are applied to Ethernet or port channel interfaces to manage traffic.

The exit command saves pending policy map changes to running-config and returns the switch to the global configuration mode. Policy map changes are also saved by entering a different configuration mode. The abort command discards pending changes, returning the switch to the global configuration mode.

The no policy-map type quality-of-service and default policy-map type quality-of-service commands delete the specified policy map by removing the corresponding policy-map type quality-of-service command and its associated configuration. The policy-map and policy-map type quality-of-service commands are equivalent.

service-policy type pbr (Interface mode)

The service-policy pbr command applies the specified Policy-Based Routing (PBR) policy map to the configuration mode interface. A PBR policy map is a data structure that consists of class maps that identify specific packets and the next hops for those packets. Policy maps are applied to Ethernet or port channel interfaces to manage traffic. Only one service policy is supported per interface.

The no service-policy pbr and default service-policy pbr commands remove the service policy assignment from the configuration mode interface by deleting the corresponding service-policy pbr command from running-config.

Command Mode

Interface-Ethernet Configuration

Interface-Port-Channel Configuration

Interface-VLAN Configuration

Command Syntax

service-policy type pbr TRAFFIC_DIRECTION map_name

no service-policy type pbr TRAFFIC_DIRECTION map_name

default service-policy type pbr TRAFFIC_DIRECTION map_name

Parameters
  • TRAFFIC_DIRECTION IP address or peer group name. Values include:
    • input Policy map applies to inbound packet streams.
  • map_name Name of policy map.

Guidelines

A policy map that is attached to a port channel interface takes precedence for member interfaces of the port channel over their individual interface Ethernet configuration. Members that are removed from a port channel revert to the policy map implementation specified by its interface Ethernet configuration.

Related Commands

Example

This command applies the PBR policy map PMAP1 to interface Ethernet 8.
switch# config
switch(config)# interface ethernet 8
switch(config-if-Et8)# service-policy type pbr input PMAP1
switch(config-if-Et8)#

service-policy type qos (Interface mode)

The service-policy command applies a specified policy map to the configuration mode interface. A policy map is a data structure that identifies data traffic through class maps, then specifies actions to classify the traffic (by setting the traffic class), mark the traffic (by setting the cos and dscp values), and police the traffic (by setting the police rate) through data packet field modifications.

The no service-policy and default service-policy commands remove the service policy assignment from the configuration mode interface by deleting the corresponding service-policy command from running-config.

Command Mode

Interface-Ethernet Configuration

Interface-Port-Channel Configuration

Interface-VLAN Configuration

Command Syntax

service-policy [type qos] TRAFFIC_DIRECTION map_name

no service-policy [type qos] TRAFFIC_DIRECTION map_name

default service-policy [type qos] TRAFFIC_DIRECTION map_name

Parameters
  • type qos Parameter has no functional effect.
  • TRAFFIC_DIRECTION Direction of data stream to which command applies. Options include:
    • input Policy map applies to inbound packet streams.
    • map_name Name of policy map.

Guidelines

A policy map that is attached to a port channel interface takes precedence for member interfaces of the port channel over their individual interface Ethernet configuration. Members that are removed from a port channel revert to the policy map implementation specified by its interface Ethernet configuration.

DCS-7500E and DCS-7280E limitations:

  • A maximum of 31 QoS service policies per chip may be applied on L3 interfaces.
  • Applying different QoS service policies to an SVI and its member interfaces causes unpredictable behavior.
  • When an SVI on which QoS service policies are applied experiences partial failure due to limited hardware resources, a forwarding agent restart causes unpredictable behavior.
  • Policy-map programming may fail when QoS service policies are applied on two SVIs if an event causes a member interface to switch membership from one to the other. To change the VLAN membership of an interface in this case, remove the interface from one VLAN before adding it to the other.
  • Outgoing COS rewrite is not supported.
  • QoS policy-map counters are not supported.

DCS-7010, DCS-7050, DCS-7050X, DCS-7250X, and DCS-7300X limitations:

  • When the same policy map is applied to multiple SVIs, TCAM resources are not shared.
  • A policy map applied to an SVI results in TCAM allocation on all chips whether SVI members are present or not.
  • Applying different QoS service policies to an SVI and its member interfaces causes unpredictable behavior.

The no shape and default shape commands remove the maximum bandwidth restriction for the configuration mode class by deleting the corresponding bandwidth command from running-config.

Command Mode

Policy-map-class (control plane) configuration accessed through class (policy-map (control-plane) Petra)

Command Syntax

shape kbps kilobits

no shape

default shape

Parameters

kilobits Maximum data rate in kilobits per second. Value ranges from 1 to 10000000.

Static Classes Default Shape

Petra platform switches define these default shapes for static classes:
  • copp-system-bpdu 2500 copp-system-l3destmiss 2500
  • copp-system-default 2500 copp-system-l3slowpath 2500
  • copp-system-igmp 2500 copp-system-l3ttl0 2500
  • copp-system-ipbroadcast 2500 copp-system-l3ttl1 2500
  • copp-system-ipmc 2500 copp-system-lacp 2500
  • copp-system-ipmcmiss 2500 copp-system-lldp 2500
  • copp-system-ipmcrsvd 2500 copp-system-unicast-arp 2500
  • copp-system-ipunicast No Limit

Guidelines

Petra does not support all discrete rate values. When a specified discrete value is not supported, the switch converts the rate to the next highest discrete value that it supports. The show command displays the converted rate and not the user-configured rate.

Example

These commands configure the maximum bandwidth of 2000 kbps for data traffic specified by the class map copp-system-lldp of the default control-plane policy map. Because the switch does not support the discrete value of 2000 kbps, it converts the bandwidth up to 2115 kbps.
