Command Line Interface Reference for the ProSafe 7300S Series Layer-3 Stackable Switches, 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.

IGMP Snooping Commands
v3.0, January 2008
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.
