This feature extends sampled flow tracker to support the selective sampling of certain traffic types (specified globally), such as routed IPv4, routed IPv6, and MPLS pop and route IPv4, per interface. The feature is applicable on interfaces, subinterfaces, port channels, and port channel subinterfaces.

The feature allows egress sFlow sampling to be enabled per a subinterface. The egress sFlow sampling per a subinterface configuration will only have effect when egress sFlow sampling is disabled on the parent interface as egress sFlow sampling on the parent interface includes traffic on all subinterfaces.

This feature provides support for packet and byte ingress counters for IPv6 multicast routes.
