Setting the group membership time

Group membership time defines how long a group will remain active on an interface in the absence of
a group report. Possible values are from 5 - 26000 seconds and the default value is 260 seconds.

To define an IGMP membership time of 240 seconds, enter the following.

device(config)# ip igmp group-membership-time 240

Syntax: [no] ip igmp group-membership-time 5-26000

Setting the maximum response time

The maximum response time defines the maximum number of seconds that a client can wait before it
replies to the query sent by the router. Possible values are 1 - 25. The default is 10.

To change the IGMP maximum response time, enter a command such as the following at the global
CONFIG level of the CLI.

device(config)# ip igmp max-response-time 8

Syntax: [no] ip igmp max-response-time num

The num parameter specifies the maximum number of seconds for the response time. Enter a value
