27.14 bridge multicast unregistered

Use the bridge multicast unregistered Interface Configuration (Ethernet,
Port-Channel) mode command to configure the forwarding state of unregistered
multicast addresses. Use the no form of this command to restore the default
configuration.
Syntax
bridge multicast unregistered
no bridge multicast unregistered
Parameters
•
forwarding—Forwards unregistered multicast packets.
•
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.
