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

This feature introduces the ability to match on 1) any BGP aggregate contributor or 2) a specific BGP aggregate’s

This feature implements RFC 5310 that allows IS-IS PDUs to be authenticated using following secure hash algorithms (SHA): SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512. The feature is supported in both default and non-default vrf. Unlike the existing authentication scheme based on MD5 and ClearText, with this feature two IS-IS nodes can be configured with different SHA algorithm and secret-key and can still exchange IS-IS PDUs. 

EOS version 4.21.3F provides additional clear commands extending what is already available in EOS as described by the below TOI

Time stamping is an important tool for network engineering and performance analysis. EOS-4.21.3F adds support for payload timestamping of all GRE encapsulated mirrored packets at line rate (initially only supported on the 7500R/7280R/7500R2/7280R2 series). A timestamp is taken on ingress and inserted into the GRE encapsulated mirrored packet payload at egress.

RIB Route Control is a collection of mechanisms for controlling how IP routing table entries get used. Next hop

The ‘show interfaces interactions’ command aims to provide users a resource that explains various relationships between ethernet interfaces. It describes interactions in which a configuration on an interface causes another set of interfaces to become inactive or have reduced capabilities.Examples include a primary interface consuming subordinate interfaces to service a four-lane speed or platform restrictions that require four interfaces of a port to operate at the same speed.
