IGMP Snooping Commands

IGMP leave was received from a specific port, the current port is deleted from 

the member list of that Multicast group. To configure the default leave-time-

out, use the no form of this command.

ip igmp snooping leave-time-out [

time-out | immediate-leave]

•

time-out  —  Specifies the leave-time-out in seconds. (Range: 1-25)

•

immediate-leave — Specifies that the port should be removed 

immediately from the members list after receiving IGMP Leave.

The default leave-time-out configuration is 10 seconds.

Interface Configuration (gigabitethernet, port-channel, tengigabitethernet) 

mode

The leave timeout should be set greater than the maximum time that a host 

is allowed to respond to an IGMP Query.
Use immediate leave only where there is only one host connected to a port. 

The following example configures the host leave-time-out to 15 seconds.

console(config-if-1/0/1)#ip igmp snooping leave-time-

out 15

Use the ip igmp snooping mrouter-time-out command in Interface 

Configuration mode to configure the mrouter-time-out. This command is 

used for setting the aging-out time after Multicast router ports are 

automatically learned. To reset to the default mrouter-time-out, use the no 

form of this command.
