Examples
The following example forbids MAC address 0100.5e02.0203 on port 2/e9 within VLAN 8.
bridge multicast unregistered
The bridge multicast unregistered Interface Configuration mode command configures the
forwarding state of unregistered multicast addresses. Use the no form of this command to return to
default.
Syntax
• bridge multicast unregistered { forwarding | filtering }
• no bridge multicast unregistered
• forwarding — Forward unregistered multicast packets.
•
filtering — Filter unregistered multicast packets. See usage guidelines for the case where
the port is a router port.
Default Configuration
Forwarding
Command Modes
Interface configuration (Ethernet, Port-Channel) mode
Default Configuration
• Unregistered multicast filtering should not be enabled on ports that are connected to routers,
because the 224.0.0.x address range should not be filtered. Routers would not necessarily send
IGMP reports for the 224.0.0.x range.
Examples
This example configures the forwarding state of unregistered multicast addresses to allow
forwarding.
Console(config)# interface vlan 8
Console(config-if)# bridge multicast address 0100.5e.02.0203
Console(config-if)# bridge multicast forbidden address
0100.5e02.0203 add ethernet 2/e9
Console (config)# bridge multicast unregistered forwarding
