Syntax: show ip multicast pimsm-snooping group-address [source-ip-address]

The Brocade device determines which address is the group address and which one is the source
address based on the ranges that the address fall into. If the address is within the range of source
addresses, then the router treats it as the source address. Likewise, if the address falls in the range of
group addresses, then the router assumes it is a group address.

The following table describes the information displayed by the show ip multicast pimsm-snooping
command.

vlan

The VLAN membership ID of the source.

port

The port on which the source is sending traffic. In this example, the port number is 1.
