interface-list | port-channel port-channel-number-list}
no bridge multicast forbidden forward-all
Parameters
• add — Forbids forwarding all multicast packets.
• remove — Does not forbid forwarding all multicast packets.
• interface-list — Separates nonconsecutive Ethernet ports with a comma
and no spaces; a hyphen is used to designate a range of ports.
• port-channel-number-list — Separates nonconsecutive port-channels with
a comma and no spaces; a hyphen is used to designate a range of
port-channels.
Default Setting
This setting is disabled.
Command Mode
Interface Configuration (VLAN) mode
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
In this example, forwarding all multicast packets to 1/e1 with VLAN 2 is forbidden.
Console(config)# interface vlan 2
Console(config-if)# bridge multicast forbidden forward-all add ethernet
1/e1
