Command Usage

The switch must be using IGMPv2 for this command to take effect.

This command defines the time after a query, during which a response is expected from a multicast client. If a querier has sent a number of queries defined by the ip igmp snooping query-count, but a client has not responded, a countdown timer is started using an initial value set by this command. If the countdown finishes, and the client still has not responded, then that client is considered to have left the multicast group.

Example

The following shows how to configure the maximum response time to 20 seconds:

Console(config)#ip igmp snooping query-max-response-time 20 Console(config)#
