198.92.36.129
10.1.37.2
The following is sample output from the show ip pim interface command with a count:
Switch# show ip pim interface count
Address

171.69.121.35
198.92.12.73
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.
Switch# show ip pim interface count
States: FS - Fast Switched, H - Hardware Switched
Address
192.1.10.2
192.1.11.2
192.1.12.2
192.1.23.2
192.1.24.2
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, perform one of these tasks:
Command
Switch# clear ip mroute
Switch# clear ip mfib counters
Switch# clear ip mfib fastdrop
IP multicast routes can be regenerated in response to protocol events and as data packets arrive.
