Examples
In this example the MAC address 01:00:5e:02:02:03 is forbidden on port g9 within VLAN 8.
Console (config)# interface vlan 8
Console (config-if)# bridge multicast address 01:00:5e:02:02:03
Console (config-if)# bridge multicast forbidden address
01:00:5e:02:02:03 add ethernet g9
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)# bridge multicast unregistered forwarding
