Example
In this example, all multicast packets on port 1/e8 are forwarded.
bridge multicast forbidden forward-all
The bridge multicast forbidden forward-all Interface Configuration (VLAN) mode command
forbids a port to be a forward-all-multicast port. To restore the default configuration, use the no
form of this command.
Syntax
bridge multicast forbidden forward-all { add | remove } { ethernet interface-list | port-
channel
port-channel-number-list }
no bridge multicast forbidden forward-all
• add — Forbids forwarding all multicast packets.
•
remove — Does not forbid forwarding all multicast packets.
•
interface-list — Separates non-consecutive Ethernet ports with a comma and no spaces; a
hyphen is used to designate a range of ports.
•

User Guidelines
• IGMP snooping dynamically discovers multicast router ports. When a multicast router port is
discovered, all the multicast packets are forwarded to it unconditionally.
• This command prevents a port from becoming a multicast router port.
