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 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 the multicast group replacement feature globally for all ports in IGMP-snooping view or for a port in interface view. For a port, the port-specific configuration takes priority over the global configuration.
Examples
# Globally enable the multicast group replacement feature for VLAN 2.
<Sysname> system-view [Sysname] igmp-snooping [Sysname-igmp-snooping] overflow-replace vlan 2
