igmp router [port-list] [enable | disable]

leads towards a Layer 3 multicast device or IGMP querier.

COMMAND USAGE
If IGMP snooping cannot locate the IGMP querier, you can manually
designate a port which is connected to a known IGMP querier (i.e., a
multicast router/switch). This interface will then join all the current
multicast groups supported by the attached router/switch to ensure that
multicast traffic is passed to all appropriate interfaces within the switch.
