Bridge Multicast Forward-All - Cisco 300 Series Cli Manual

Address Table Commands
78-21075-01 Command Line Interface Reference Guide
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 gi1:
switchxxxxxx(config)#
switchxxxxxx(config-if)#
