Configuring a Static MAC Address

You can configure MAC addresses for the switch. These addresses are static MAC addresses.
You can also configure a static MAC address in interface configuration mode or VLAN configuration
Note
mode.
To configure a static MAC address, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config-)# mac-address-table
static mac_address vlan vlan-id {drop |
interface {type slot/port} |
port-channel number} [auto-learn]
This example shows how to put a static entry in the MAC address table:
switch# configure terminal
switch(config)# mac-address-table static 12ab.47dd.ff89 vlan 3 interface ethernet 2/1
To delete a static MAC address, perform this task:
Command
switch(config-if)# no mac-address-table
static mac_address vlan vlan-id
You can use the mac-address-table static command to assign a static MAC address to a virtual interface.

Configuring the Aging Time for the MAC Table

You can configure the amount of time that an entry (the packet source MAC address and port that packet
ingresses) remain in the MAC table.
You can also configure MAC aging time in interface configuration mode or VLAN configuration mode.
