This feature allows capturing packets and byte counts at high resolution on physical interfaces, down to 1 ms granularity. Allows for detecting anomalous packet flows, or confirming the expected bandwidth usage. Requires selecting a set of interfaces to sample, a time resolution, and sampling duration.

This is an addendum to the “IP in IP decapsulation” document.The Decap Group counters feature allows the device to count packets and octets that are decapsulated at the termination of the Decap Group.
