The following is sample output from the show ip pim interface command with a count when IP
multicast is enabled. The example lists the PIM interfaces that are fast-switched and process-switched,
and the packet counts for these. The H is added to interfaces where IP multicast is enabled.

Clearing Tables and Databases

You can remove all contents of a particular cache, table, or database. Clearing a cache, table, or database
might be necessary when the contents of the particular structure have become, or are suspected to be,
invalid.
To clear IP multicast caches, tables, and databases, enter one of these commands:
Command
Switch# clear ip mroute
Switch# clear ip mfib counters
Note IP multicast routes can be regenerated in response to protocol events and as data packets arrive.
