H3C IE4300 Command Reference Manual page 1620

Parameters
vlan vlan-list
VLAN by its ID or a range of VLANs in the form of
ID is in the range of 1 to 4094. If you do not specify a VLAN, this command takes effect on all VLANs.
Usage guidelines
This command takes effect only on the IPv6 multicast groups that a port joins dynamically.
You can enable IPv6 multicast group replacement globally for all ports in MLD-snooping view or for a
port in interface view. For a port, the port-specific configuration takes priority over the global
configuration.
