no form of this command.

multicast filtering-mode {forward-all | forward-unregistered | filter-unregistered} no multicast filtering-mode

Parameters forward-all forward-unregistered filter-unregistered

Specifies to flood all multicast packets based on the VLAN domain.

Specifies to forward the registered multicast packets based on the forwarding table, and flood all un-registered multicast packets based on the VLAN domain.

Usage Guideline

When a multicast packet arrives, the switch will look up forwarding table for this packet. If the lookup failed, the destination group is an unregistered group.

A forwarding entry lookup failed multicast packet is called unregistered packet, which will be forwarded according to the multicast filter mode setting on the VLAN, which might be VLAN flooding or dropping.

To verify your configuration, use the command show multicast filtering-mode.
