undo igmp-snooping overflow-replace [ vlan vlan-list ]
View
Ethernet interface view, port group view
Parameters
vlan vlan-list: Defines one or multiple VLANs. You can provide up to 10 VLAN lists, by
each of which you can specify an individual VLAN in the form of vlan-id, or a VLAN
range in the form of start-vlan-id to end-vlan-id, where the end VLAN ID must be
greater than the start VLAN ID. The effective range of a VLAN ID is 1 to 4094.
Description
Use the igmp-snooping overflow-replace command to enable the multicast group
replacement function on the current port(s).
Use the undo igmp-snooping overflow-replace command to disable the multicast
group replacement function on the current port(s).
By default, the multicast group replacement function is disabled.
Note that:
This command works on IGMP Snooping–enabled VLANs and VLANs with IGMP
enabled on the corresponding VLAN interfaces.
If you do not specify any VLAN in Ethernet interface view, the command will take
effect on the port no matter which VLAN the port belongs to; if you specify a VLAN
or multiple VLANs, the command will take effect on the port only if the port belongs
to the specified VLAN(s).
If you do not specify any VLAN in port group view, the command will take effect on
all the ports in this group no matter which VLANs these port belong to; if you
specify a VLAN or multiple VLANs, the command will take effect on those ports in
this group that belong to the specified VLAN(s).
