The Command-tag feature adds support for grouping multiple configuration units/commands across features using a single command-tag, which is essentially a string. This tag can then be used to enable/disable/remove/disassociate all the associated commands with the tag, using a single CLI command, instead of performing the operation individually for each configuration command.

BGP Monitoring Protocol (BMP) allows a monitoring station to connect to a router and collect all of the BGP announcements received from the router’s BGP peers. The announcements are sent to the station in the form of BMP Route Monitoring messages generated from path information in the router’s BGP internal tables. A BMP speaker may choose to send either Adj-Rib-In routes, or Loc-Rib routes (as defined by RFC9069), or both.

The feature adds support for redirecting traffic matching on traffic policy rules applied to an egress interface to a specified next-hop or next-hop group. This feature requires the packet to be recirculated a second time through the packet forwarding pipeline to get its configured single or multiple next-hops to be resolved. This is achieved by configuring traffic-policy with redirect interface action applied on egress interface in conjunction with ingress redirect next-hop action applied on the recirculation interface. Redirect interface action is used to forward the egressing packet through an interface on which traffic loop-back ( a.k.a recirculation ) is enabled.

Access Control Lists (ACL) use packet classification to mark certain packets going through the packet processor pipeline and then take configured action against them. Rules are defined based on various fields of packets and usually TCAM is used to match packets to rules. For example, there can be a rule to match the packet source IP address against a list of IP addresses, and drop the packet if there is a match. This will be expressed in TCAM with multiple entries matching the list of IP addresses. Number of entries is reduced by masking off bits, if possible. TCAM is a limited resource, so with classifiers having a large number of rules and a big field list, TCAM runs out of resources.

EOS generates a single system-defined colored tunnel RIB for colored next hop resolution. When colored tunnels to the same destination address are learned from multiple protocols, a fixed preference that is associated with each protocol is used to determine the winning tunnel. This feature provides the ability to override the preference for all colored tunnels from a protocol in order to achieve non-default ordering of tunnels.

Support for independently editing packets copied to multiple tool interfaces.
A Tap Aggregation steering policy can redirect and replicate incoming traffic streams, as well as apply various packet editing actions, e.g., VLAN identity tagging, MAC address rewrite, timestamping, header removal, etc.

The Unified Forwarding Table (UFT) is memory that is shared between Layer2 and Layer3 lookup tables with capabilities for variable partitions. Rather than separate Layer2 and Layer3 lookup tables of fixed size, the UFT may be partitioned to support user-requested combinations of Layer2 and Layer3 lookup table sizes.

This feature allows selecting Differentiated Services Code Point (DSCP) and Traffic Class (TC) values for packets at VTEPs along VXLAN encapsulation and decapsulation directions respectively. DSCP is a field in IP Header and TC is a tag associated with a packet within the switch, both influence the Quality of Service the packet receives. This feature can be enabled via configuration as explained later in this document.
