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

A variety of dynamic counter features, primarily configured by the [no] hardware counter feature [feature] CLI commands, may be enabled simultaneously. Compatibility of these features has been enhanced to allow for greater flexibility in simultaneously enabled counter features. 

IS IS flexible algorithm (FlexAlgo) provides a lightweight, simplified mechanism for performing basic traffic

This feature will allow the user to select whether port mirror destinations of type GRE tunnel include the optional “key” field in the GRE header on certain platforms. The key field allows the user to uniquely identify a particular packet flow. The feature also allows the user to specify the value of the 32 bit key field. The format of the key field within the GRE header can be seen in RFC 1701 - Generic Routing Encapsulation (GRE).

Generic UDP Encapsulation (GUE) is a general method for encapsulating packets of arbitrary IP protocols within a UDP tunnel. GUE provides an extensible header format with optional data. In this release, the ability to encapsulate MPLS over GUE packets of variant 1 header format has been added. 

Network administrators require access to flow information that passes through various network elements, for the purpose of analyzing and monitoring their networks. This feature provides access to IP flow information by sampling traffic flows in ingress and/or egress directions on the interfaces on which it is configured.
