Media Access Control Security (MACsec) is an industry standard encryption mechanism that protects all traffic

This feature adds support for a selected set of configured interfaces to collect egress flow samples. Egress sFlow can be configured on Ethernet and Port-Channel interfaces, and on subinterfaces on select platforms. Hardware acceleration is not currently supported for egress sFlow and all sample processing is performed in software.

Topology Independent Fast Reroute, or TI-LFA, uses IS-IS SR to build loop-free alternate paths along the post-convergence path. These loop-free alternates provide fast convergence.

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.

BGP routing information often contains more than one path to the same destination network. The BGP best-path selection algorithm determines which of these paths should be considered as the best path to that network.

Two rate three color marker (TrTCM) meters an incoming packet stream and marks the packets based on two rates, PIR

Unidirectional links is a feature that configures an Ethernet interface transmit and receive paths to be independent. Specifically, the transmit path can be up or down independent of the receive path being up or down.

Prior to EOS 4.24.1F, per-destination steering into an SR Policy was only supported for IP unicast BGP routes in the default VRF. Support for additional AFI/SAFIs were added as follows: EOS 4.24.2F: L2 EVPN — EOS 4.27.2F: BGP Labeled Unicast
