In this example, the network in VLAN 1 is 10.251.30.0/24. Configuring the IP
address to 10.251.30.1 will ensure that this device will be the active querier in
VLAN 1.
After reconfiguring the IP address of the IGMP querier’s interface, repeat step 2.
Is the IGMP Snooping VLAN fixed only on specific VLANs?
By default, IGMP join/leave are processed in all VLAN. If the IGMP snooping VLAN is
configured as “Fixed”, this means that only IGMP join/leave from the configured
IGMP snooping VLAN lists are processed. In this case, either reconfigure the mode to
“Auto”, or configure the VLAN where multicast clients are being processed.
