Syntax 
ip igmp snooping multi-vlan-config  [  vlan-id  ] [ rtime  router-time  |  mtime 
member-time  |  rport interface {  gigabitEthernet  port-list  |  port-channel 
port-channel-id } ] 
no ip igmp snooping multi-vlan-config  [  rtime  router-time  |  mtime 
member-time  |  rport interface {  gigabitEthernet  port-list  |  port-channel 
port-channel-id } ] 
Parameter 
vlan-id —— The ID of the multicast VLAN desired to create or modify, ranging 
from 2 to 4094. If not specified, the default multicast VLAN will be selected. 
router-time  ——  Router Port Time. Within this time, if the switch does not 
receive IGMP query message from the router port, it will consider this port is not 
a router port any more. Router Port Time ranges from 60 to 600 in seconds. By 
default, it is 0 and the global router-time will be used. 
member-time —— Member Port Time. Within this time, if the switch does not 
receive IGMP report message from the member port, it will consider this port is 
not a member port any more. Member Port Time ranges from 60 to 600 in 
seconds. By default, it is 0 and the global member-time will be used. 
port-list —— The list of Ethernet ports. 
port-channel-id —— The ID of the port channels.
