Configuring the Querier Capability. The default querier capability is

“enabled”. This means that the switch will be allowed to operate as the querier on a VLAN (but does not force it to do so). This command disables or reenables the querier capability. (Refer also to “General IGMP Operation” on page 12-11.)

Syntax: [no] vlan < vlan-id > ip igmp querier

Default: Yes

 

HPswitch(config)# no vlan 1 ip

Disables the querier capability

igmp querier

on VLAN 1.

HPswitch> show ip igmp config
