To display PIM SM snooping information for a specific (source, group) pair, enter the following
command at any level of the CLI.
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.
Multicast Group The IP address of the multicast group.
NOTE: The fid and camindex values are used by Brocade Technical Support for
troubleshooting.
