source address when generating periodic queries. The no form of this
command disables IGMP Snooping Querier on the system. Use the optional
address parameter to set or reset the querier address.
If a VLAN has IGMP Snooping Querier enabled, and IGMP Snooping is
operationally disabled on it, IGMP Snooping Querier functionality is disabled
on that VLAN. IGMP Snooping Querier functionality is re-enabled if IGMP
Snooping is operational on the VLAN.
The IGMP Snooping Querier application sends periodic general queries on
the VLAN to solicit membership reports.

Command Mode
Global Configuration mode
User Guidelines
When using the command in Global Configuration mode to configure a
snooping querier source address, the IPv4 address is the global querier
address. When using the command in VLAN Configuration mode to
configure a snooping querier source address, the IPv4 address is the querier
address for the VLAN. If there are no global or VLAN querier addresses
configured, then use the management IP address as the IGMP snooping
querier source address. Using all zeros for the querier IP address removes it.
The VLAN IP address takes precedence over the global IP address.
