Activates the Internet Group Management Protocol (IGMP) snooping querier on a VLAN.
By default, the IGMP snooping querier is enabled.
VLAN configuration mode
Multicast routers use IGMP snooping to learn which groups have members on their attached physical networks. The snooping querier sends IGMP queries to trigger IGMP responses from devices that are to receive IP multicast traffic. The IGMP snooping querier receives these responses and maps the appropriate forwarding addresses.
The no ip igmp snooping querier enable form of the command disables the IGMP snooping querier.
The following example enables the IGMP snooping querier on a VLAN.
device(config)# vlan 1 device(config-vlan-1)# ip igmp snooping querier enable
