Parameters
interval: Sets the maximum response time for IGMP general queries, in the range of 1 to 25 seconds.
Usage guidelines
You must enable IGMP snooping for a VLAN before you execute this command for the VLAN.
The configuration made in VLAN view is only effective on the current VLAN, and it takes preference over
the global configuration.
To avoid mistakenly deleting multicast group members, make sure the interval for sending IGMP general
queries is larger than the maximum response time for IGMP general queries.
Examples
# In VLAN 2, enable IGMP snooping, and set the maximum response time for IGMP general queries to
5 seconds.
