Configuring MAC Addresses

Configuring MAC Addresses

Configuring Static MAC Addresses

You can configure static MAC addresses for the switch. These addresses can be configured in interface
configuration mode or in VLAN configuration mode.
Procedure
Step 1
Step 2
Step 3
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 1/4
switch(config) #

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) remains in the MAC table. MAC aging time can be configured in either interface configuration
mode or in VLAN configuration mode.
