Changing the Maximum Query Response Time for IGMPv2

If you are using IGMPv2, you can change the maximum query response time advertised in IGMP
queries. The maximum query response time enables the switch to quickly detect that there are no more
directly connected group members on a LAN. Decreasing the value enables the switch to prune groups
faster.
Beginning in privileged EXEC mode, follow these steps to change the maximum query response time.
This procedure is optional.
