Usage guidelines
You must enable MLD snooping for a VLAN before you configure this command for the VLAN.
The configuration made in VLAN view is only effective on the current VLAN and takes preference over the
global configuration.
Examples
# Enable MLD snooping for VLAN 2 and set the maximum response delay for MLD general queries to 5
seconds.
<Sysname> system-view
[Sysname] mld-snooping
[Sysname-mld-snooping] quit
[Sysname] vlan 2
[Sysname-vlan2] mld-snooping enable

Parameters
vlan vlan-list: Specifies a space-separated list of up to ten 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 this option is not specified, this command takes effect for all VLANs.
Usage guidelines
This command is effective on the IPv6 multicast groups that a port dynamically joins. If you configure the
port as a static member port for an IPv6 multicast group, this command is not effective on the IPv6
multicast group.
The configuration made in proper interface view is only effective on the current port and takes preference
over the global configuration.
