AT-8000S-S94-3.0 Command Line Interface User’s Guide
User Guidelines
Before defining forbidden ports, the Multicast group should be registered.
Example
The following example configures MAC address 0100.5e02.0203 to be forbidden 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
Parameters
•
forwarding — Forwards unregistered multicast packets.
• filtering — Filters unregistered multicast packets. See the usage guidelines for cases where the port is a
router port.
Default Configuration
Forwarding.
Command Mode
Interface configuration (Ethernet, Port-Channel).
User Guidelines
Do not enable unregistered multicast filtering on ports that are connected to routers, since the 224.0.0.x address
range is not filtered. Note that routers do not necessarily send IGMP reports for the 224.0.0.x range.
Example
The following example configures the forwarding state of unregistered multicast addresses to be forwarded.
bridge multicast forward-all
The bridge multicast forward-all Interface Configuration (VLAN) mode command enables forwarding all
Multicast packets on a port. Use the no form of this command to restore the default configuration.
console(config)# interface vlan 8
console(config-if)# bridge multicast address 0100.5e02.0203
console(config-if)# bridge multicast forbidden address 0100.5e02.0203 add ethernet 2/e9
console(config)# interface vlan 8
console(config-if)# bridge multicast unregistered forwarding
