IGMP Snooping Commands
v1.0, February 2007
If an interface has IGMP Snooping enabled and you enable this interface for routing or
enlist it as a member of a port-channel (LAG), IGMP Snooping functionality is disabled
on that interface. IGMP Snooping functionality is re-enabled if you disable routing or
remove port-channel (LAG) membership from an interface that has IGMP Snooping
enabled.
The IGMP application supports the following activities:
•
Validation of the IP header checksum (as well as the IGMP header checksum) and
discarding of the frame upon checksum error.
•
Maintenance of the forwarding table entries based on the MAC address versus the IP
address.
•
Flooding of unregistered multicast data packets to all ports in the VLAN.
