Maintenance Mode
This section describes configuration for performing maintenance of switch elements.
Overview
- eos image upgrade.
- Initial configuration or reconfiguration of a production system.
- Replacement of hardware.
- Changing linecards or transceiver modules.
- Replace, reattach, and reroute cables.
Maintenance mode uses BGP to divert traffic away from the switch on which the maintenance tasks need to be performed, minimizing traffic impact. You can set the traffic thresholds and time limits at which the switch, or parts of the switch, is considered to be available for maintenance tasks.
- Rerouting of traffic when the mode is activated during operation and other routes are present.
- Replacement of hardware in modular systems or systems with redundant hardware.
The switch is placed into maintenance mode, serviced, and then returned to normal operation.
Maintenance Mode Elements
Maintenance mode elements include Units, Groups of interfaces and BGP Peers, and Profiles. Arista Network switches provide maintenance mode operations performed on a fundamental, configurable element, referred to as a Unit. Maintenance mode will quiesce a unit, which places the unit into maintenance mode by gracefully transitioning traffic away from it.
The most common maintenance mode operations such as removing from service an entire switch system or individual components of the switch, including a single linecard, interface, or BGP peer, can be achieved using minimal configuration.
Units
Units are configurable maintenance mode elements that comprise a collection of various groups. In addition, units contain policies which decide whether the member groups should be put into maintenance mode automatically upon boot. Built-in units are configured by default, such as the System unit representing the entire system. All maintenance mode operations are executed at the unit level.
An interface, interface range, and BGP peer (or peer-group) can be directly put under maintenance.
Built-in Units
There are various built-in units such as System and Linecard<n>. Fixed systems contain only one built-in unit called System, which comprises the interface group containing all Ethernet interfaces and sub-interfaces; and BGP groups per VRF containing all the peers in the respective VRF.
Modular Systems have both System and Linecard<n> units. Linecard<n> units are present for each linecard which comprises the Linecard<n> groups containing all Ethernet interfaces and sub-interfaces of that linecard.
User-configured Units
You can also configure customized units containing user-defined groups and policies as shown in the following example. A custom group called BG1 with a custom interface IG1 and a unit profile UP1 is created. The show command displays the details.
switch(config)# maintenance
switch(config-maintenance)# unit UNIT1
switch(config-unit-UNIT1)# group bgp BG1

IG1Groups of interfaces and BGP Peers
Maintenance mode group types include the groups for interfaces and BGP peers. Groups are identified by a group name unique to a particular group type.
By default, several built-in groups are available on the device such as linecard groups containing physical interfaces.
Built-in Groups
There are several built-in groups such as AllEthernetInterface, Linecard1, Linecard2, etc., AllBgpNeighborVrf-<vrf_name>. AllEthernetInterface is the built-in interface group which contains all physical Ethernet interfaces and sub-interfaces on the switch, and is a part of System unit. Whereas on modulars Linercard1, Linecard2, etc., are the built-in groups which contain respective linecard interfaces and sub-interfaces; and are part of the Linecard1 and Linecard2 units respectively. AllBgpNeighborVrf-<vrf_name> is the built-in BGP group which contains all the BGP peers in that particular VRF.
User-defined Groups
The following set of commands sets up a custom group (IG1) of interfaces, which includes physical ports, port-channels and SVIs.
switch(config)# group interface IG1
switch(config-group-if-IG1)# interface Ethernet1
switch(config-group-if-IG1)# interface Port-Channel1,20

switch(config-group-bgp-BG1)# neighbor BGP_PG1
switch(config-group-bgp-BG1)# vrf vrf1
switch(config-group-bgp-BG1)# exit
switch(config)#Profiles
Profiles are configurable maintenance mode elements that define policies for related software or hardware components to carry out maintenance mode operations.
Default Profiles
Default profiles are the built-in policies which are applied to groups interface/BGP and unit.
The default profile is used in the absence of an explicit interface/BGP profile associated with the group, or explicit unit profile associated with the unit.

switch(config)#Maintenance Mode Features
Arista Network switches provide maintenance mode features including rate monitoring, BGP maintenance route map, on-boot maintenance, and EventMgr integration.
Rate Monitoring
Rate monitoring provides a mechanism to monitor traffic on interfaces identified for maintenance. You can set the traffic threshold and a time limit for the interface to be shutdown for maintenance tasks.
A shutdown parameter can be configured in the interface profile that signals the interface to be shutdown after it has entered maintenance mode.
The max-delay parameter specifies the maximum number of seconds to allow for traffic to dissipate from the interface before the interface is shutdown. The default interface profile settings are shown in the output of the show maintenance profile interface default command.
BGP Maintenance Route Map
Route-maps are used within a BGP maintenance profile to tag the inbound and outbound routes in order to direct traffic away from the unit.
The default profile tags the inbound and outbound routes with the global shutdown community. Other methods can be configured under the route-map such as alternate communities, or by using AS_PATH prepend operations.
On-boot Maintenance
- The unit is placed into maintenance mode prior to the switch reboot, and the running-config is saved prior to switch boot-up.
- The on-boot property in the unit maintenance profile specifies that the unit
will be placed into maintenance mode as part of boot-up, and remains so for the
specified duration. Note: The duration value in the on-boot unit maintenance profile starts as soon as the unit is put into maintenance mode on boot-up.
Single Event Upset handling
All electronic devices are subject to interference from cosmic radiation. Arista products use a combination of hardware and software to automatically detect and correct the results of this interference. For instance, many chip memories contain parity or Error Correcting Code (ECC) bits. However, Single Event Handling (SEU) is a randomevent, and following configuration determines the handling behavior.
switch(config)# platform sand seu
switch(config-sand-seu)#The system,by default corrects the first instance of an ECC or parity event without any logging. If a further error occurs within a 4 hour time window, related to the first or not, a log message will be emitted.
The default 4 hours logging window can be changed as following. For example, a second SEU is detected within 3 hours of a prior SEU.
switch(config-sand-seu)# log window 10800 secondsStatic memories are used by hardware to hold configuration to determine switching behaviour. When SEUs occur, repairs are made automatically. The following command disables automatic repair by a specific agent.
switch(config-sand-seu)# repair table static manager SandFap disabledThe following command disables automatic repair by a specific memories, overriding any specific configurations.
switch(config-sand-seu)# repair table static disabledThe following command disables automatic repair of fabric chip memories on the modular or fixed systems which use fabric chip.
switch(config-sand-seu)# repair table fabric manager SandFabric disabled
switch(config-sand-seu)# repair table fabric disabledswitch(config-sand-seu)# repair table dynamic disabledswitch(config-sand-seu)# repair table dynamic action reset full disabledswitch(config-sand-seu)#repair action reset full interval 43200 secondsShow Command
SEU events generate interrupts, it can be seen along with all other interrupts.

-------------------------------------------------------------------------------------- Ecc_1bErr - Single bit error in ECC protected memory, corrected automatically in hardware.
- Ecc_2bErr - Two bit error in ECC protected memory detected, requires software correction.
- ParityErr - Single bit error in parity protected memory detected, requires software correction.
Single bit ECC errors do not affect correct operation of the switch. Two bit ECC and parity errors can disrupt correct operation, for example, by dropping one or more packets, or by mis-forwarding packets. The exact effect depends on the memory and location affected by the SEU.
Maintenance Mode Configuration
You can configure maintenance mode for the entire device, specific linecards, or any other Unit. You can set up configuration for maintenance mode for the device at boot-up or while it is running.
Unit Configuration
-
switch(config-maintenance)# unit Linecardn -
switch(config)# group interface Linecardn
- AllEthernetInterface - a built-in interface group which contains all physical Ethernet interfaces on the switch on a fixed system.
- Linecardn - a built-in interface group which contains all interfaces for the linecard numbered n for modular systems.
- AllBgpNeighborVRF-<vrf_name> - a built-in BGP group which contains all the BGP peers in the named VRF.
For each Linecard n, there is a built-in unit which consists of all the Linecardn groups.
By default, the default interface and BGP profiles are applied to the built-in interface and BGP groups and the default built-in unit profile is applied to the built-in unit. You can also configure your own profiles and choose a default.
In the following example, traffic is flowing through multiple switches in the spine to and from one switch to another, when you elect to put one of the Units (entire switch or parts thereof) in the spine switch in maintenance mode. The traffic is then gracefully steered away from the Unit, provided other paths are available. Traffic will continue to flow through the Unit placed into maintenance mode, if no other path is available.

- Use quiesce config, or
- Use on-boot profile
Using quiesce config
You must perform the following tasks to place the Unit in maintenance mode on boot-up using the quiesce command.
Using on-boot profile
The on-boot property in the Unit maintenance profile specifies that the Unit will be placed into maintenance mode as part of boot-up for the specified duration. You must perform the following tasks to use this method.
Interface-level Maintenance Mode Configuration
To configure the maintenance mode at interface-level, you must perform the following tasks:
Entering Maintenance Mode
Enter configuration commands unit and quiesce using the maintenance profile bgp mode command to place the switch into maintenance mode. The following code sequence places unit foo, the interface 3/3, and BGP 1.1.1.1 in maintenance mode.
Example
switch(config)# maintenance
switch(config-maintenance)# unit foo
switch(config-unit-foo)# quiesce
switch(config-unit-foo)# exit
switch(config-maintenance)# interface ethernet 3/3
switch(config-maint-if-Et3/3)# quiesce
switch(config-unit-if-Et3/3)# exit
switch(config-maintenance)# bgp 1.1.1.1
