Use the clear multicast statistics command to reset multicast traffic counters to zero. After the command completes successfully, the counters begin collecting new statistics.

Syntax:

clear multicast statistics

The example below shows the output of the "show mroute detail" command before clearing the statistics.

supervisor@rtbrick.net: cfg> show mroute detail
