mac-address-table static

To configure the static MAC addresses for a VLAN interface or drop unicast traffic for a MAC address
for a VLAN interface, use the mac-address-table static command. To remove the static MAC address
configurations, use the no form of this command.
Syntax Description
mac-addr
vlan vlan-id
interface type
drop
Defaults This command has no default settings.
Command Modes Global configuration mode
Command History Release
12.1(13)EW
Usage Guidelines When a static MAC address is installed, it is associated with a port.
The output interface specified must be a Layer 2 interface and not an SVI.
If you do not enter a protocol type, an entry is automatically created for each of the four protocol types.
Entering the no form of this command does not remove the system MAC addresses.
When removing a MAC address, entering interface int is optional. For unicast entries, the entry is
removed automatically. For multicast entries, if you do not specify an interface, the entire entry is
removed. You can specify the selected ports to be removed by specifying the interface.
Examples This example shows how to add the static entries to the MAC address table:
Switch(config)# mac-address-table static 0050.3e8d.6400 vlan 100 interface fastethernet5/7
Switch(config)#
