User Guidelines
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
In this example, forwarding all multicast packets to g1 with VLAN 2 is
forbidden.
Console(config)#
interface vlan

Console(config-if)#
