The goal of IAR operation is to minimize the CPU processing and churn in hardware by identifying a set of nexthop adjacencies such that updating those adjacencies in-place is sufficient to correctly forward the traffic quickly for all the affected routes.

BGP Non Stop Forwarding (NSF) aims to minimize the traffic loss when the the following scenarios occur:

Bidirectional Forwarding Detection (BFD) is a protocol that provides low overhead, short duration detection of

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.

In TAP Aggregation mode, when receiving a packet whose Frame Check Sequence (FCS) is corrupted, the default behavior is to replace the bad FCS with the correct value and forward it.

This article describes a set of CLI commands to create TCAM profiles. The profile is composed of a set of TCAM features, with each feature having customized lookup key, actions and packet types to hit.
