TOI Author :: Steve Ulrich

Traffic policies applied to interfaces are used to match traffic based on packet header fields or their summarized counterparts and take configured actions against them. The match rules configured in these policies are usually installed in a prioritized hardware table (i.e., TCAM) where the action of the first-hit filter is taken. The summarized fields are also installed in various hardware tables. 

IS-IS Counters feature adds support to monitor per interface count of received, transmitted and dropped IS-IS PDUs at the Rib/ISIS agent level. The counters start getting incremented once IS-IS is enabled on an interface and persist until IS-IS is disabled on it or the Rib/Isis agent restart.
