This display shows the following information.
Displaying PIM SM Snooping Information for a Specific Source in a Group
You can display PIM SM snooping information for a specific (source, group) pair by entering commands such as
the following at any level of the CLI:
Syntax: show ip pimsm-snooping <group-address> <source-ip-address>
The Foundry 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.
This Field... Displays...
VLAN ID The port-based VLAN to which the information listed below apply and
the number of members in the VLAN.
PIM SM Neighbor list The PIM SM routers that are attached to the Layer 2 Switch’s ports in
the VLAN.
The value following “expires” indicates how many seconds the Layer 2
Switch will wait for a hello message from the neighbor before
determining that the neighbor is no longer present and removing the
neighbor from the list.
Multicast Group The IP address of the multicast group.
Note: The fid and camindex values are used by Foundry Technical
Support for troubleshooting.

report for the group, or both.

messages for the group.
