ip igmp snooping querier vlan (specific query) 
Description 
The  ip igmp snooping querier vlan command is used to configure the 
parameters for IGMP Snooping Querier to send a specific query frame. To 
return to the default configuration, please use no ip igmp snooping querier 
vlan command. 
Syntax 
ip igmp snooping querier vlan vlan-id {last-listener query-interval interval | 
last-listener query-count count | special-query source-ip ip-addr } 
no ip igmp snooping querier vlan vlan-id  {last-listener query-interval | 
last-listener query-count | special-query source-ip} 
Parameter 
vlan-id  ——  VLAN ID list, ranging from 1 to 4094. 
interval—— The time interval of sending specific query frames by IGMP 
Snooping Querier, ranging from 1 to 5 (Seconds). By default, it is 1. A specific 
query will be sent on condition that “immediate-leave” is not enabled and a 
leave frame is received. 
count—— The times of sending specific query frames by IGMP Snooping 
Querier, ranging from 1 to 5. By default, it is 2. The switch will still treat the port 
as group member until the specific frames number sent by the querier reaches 
“last-listener-query-count” and no report frame is received from the port. 
ip-addr——  The source IP of the specific query frame sent by IGMP Snooping 
Querier. It should not be a multicast IP or a broadcast IP. By default, it is 
192.168.0.1.
