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 multicast groups that a port joins dynamically.
You can enable multicast group replacement for a port in interface view or globally for all ports in
IGMP-snooping view. For a port, the port-specific configuration takes priority over the global
configuration.
