This command displays the Switch's current IGMP snooping forwarding table.
show igmp_snooping forwarding {[vlan <vlan_name 32> | vlanid <vlanid_list>]}
It provides an easy way for users to check the list of ports that the multicast group that
comes from a specific sources will be forwarded to. The packet comes from the source
VLAN. They will be forwarded to the forwarding VLAN. The IGMP snooping further restricts
the forwarding ports.
