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.
