IGMP Snooping Configuration Commands
This section describes the commands you use to configure IGMP snooping. The software
supports IGMP Versions 1, 2, and 3. The IGMP snooping feature can help conserve
bandwidth because it allows the switch to forward IP multicast traffic only to connected hosts
that request multicast traffic. IGMPv3 adds source filtering capabilities to IGMP versions 1
and 2.
set igmp
This command enables IGMP Snooping on the system (Global Config Mode) or an interface
(Interface Config Mode). This command also enables IGMP snooping on a particular VLAN
(VLAN Config Mode) and can enable IGMP snooping on all interfaces participating in a
VLAN.
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.
