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 this option is not specified, this command takes effect for all VLANs.
Usage guidelines
This command takes effect 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 does not take effect on the IPv6
multicast group.
The global configuration is effective on all ports, but it has a lower priority than the configuration made
on a specific port.
