The following shows an example output of the show ip pim mcache command.

The following shows an example output of the show ip pim flow command.

The following shows an example output of the show statistics command. The following statistics
demonstrate an example where the encapsulated multicast traffic ingresses a tunnel endpoint on port e
2, egresses and re-ingresses as native multicast traffic on the loopback port e 4, and is then forwarded
to the outbound interface e 1.

The show ip mtu command can be used to see if there is space available for the ip_default_mtu_24
value in the system, or if the MTU value is already configured in the IP table. The following shows an
example output of the show ip mtu command.
device(config-tnif-10)#show ip mtu

Syntax:show ip mtu
Clearing GRE statistics
Use the clear ip tunnel command to clear statistics related to GRE tunnels.
To clear GRE tunnel statistics, enter a command such as the following.
device(config)# clear ip tunnel stat 3
