Parameters
interval: Sets the maximum response time for IGMP general queries, in the range of 1 to 25 seconds.
Usage guidelines
The global configuration is effective on all VLANs. It has lower priority than the configuration made in a
specific VLAN.
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
# Set the global maximum response time for IGMP general queries to 5 seconds.

[Sysname] igmp-snooping

Parameters
vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its
ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to
4094. If you do not specify any VLAN, the command takes effect on all VLANs.
Usage guidelines
This command is effective on the multicast groups that a port joins dynamically. If you configure the port
as a static member port for a multicast group, this command is not effective on the multicast group.
The global configuration is effective on all ports. It has lower priority than the configuration made on a
specific port.
