•
filtering
—Filters unregistered multicast packets.
Default Configuration
Unregistered multicast addresses are forwarded.
Command Mode
Interface Configuration (Ethernet, Port-Channel) mode
User Guidelines
Do not enable unregistered multicast filtering on ports that are connected to
routers, because the 224.0.0.x address range should not be filtered. Note that
routers do not necessarily send IGMP reports for the 224.0.0.x range.
You can execute the command before the VLAN is created.
Example
The following example specifies that unregistered multicast packets are
filtered on gigabitethernet port
1/0/1
:
Console(config)#
interface
gi1/0/1
Console(config-if)#
bridge multicast unregistered filtering
bridge multicast forward-all
Use the
bridge multicast forward-all

command to enable forwarding all multicast packets for a range of ports or
port channels. Use the
no
form of this command to restore the default
configuration.
