config igmp_snooping querier
Querier (sends IGMP query packets). It the state is disabled, then the switch can
not play the role as a querier. Note that if the Layer 3 router connected to the
switch provide only the IGMP proxy function but not provide the multicast routing
function, then this state must be configured as disabled. Otherwise, if the Layer 3
router is not selected as the querier, it will not send the IGMP query packet.
Since it will not also send the multicast-routing protocol packet, the port will be
timed out as a router port.
version – Specifies the version of IGMP packet that will be sent by this VLAN.
Restrictions
Only Administrator-level users can issue this command.
Example usage:
To configure IGMP snooping querier:
DES-3200-28:4#config igmp_snooping querier vlan_name default query_interval
125 state enable
Command: config igmp_snooping querier vlan_name default query_interval 125
