Clear commands for IGMP snooping
To display PIM SM snooping information for a specific (source, group) pair, enter a command such
as the following at any level of the CLI.
Syntax: show ip multicast pimsm-snooping <group-address> []
The 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 output shows the following information.
