Layer 2 Switching Commands 303
Default Configuration
No forbidden addresses are defined.
Command Mode
Global Configuration mode
User Guidelines
Before defining forbidden ports, ensure that the multicast group is registered.
Changing an unregistered multicast address to forbidden on an mrouter port
will effectively forbid the multicast group on all ports on the switch as it
inhibits the source of the multicast group.
Examples
In this example the MAC address 0100.5e02.0203 is forbidden on port 2/0/9
within VLAN 8.
console(config)#mac address-table multicast forbidden address vlan 8
0100.5e02.0203 add interface gigabitethernet 2/0/9
mac address-table static
Use the mac address table static command in Global Configuration mode to
add a static MAC-layer station source address to the bridge table. To delete
the MAC address, use the no form of the mac address table static command.
