Command Usage
IGMP snooping dynamically discovers multicast device ports. When a multicast device port is
discovered, all the multicast packets are forwarded to it unconditionally.
This command prevents a port from becoming a multicast device port.
Example
The following command configures the device to forbid all forwarding of Multicast packets to e1
with VLAN 1.
Console(config)# interface vlan 1
Console(config-if)# bridge multicast forbidden forward-all add ethernet
e1
