Configuring MAC Addresses
Configuring a Static MAC Address
You can configure MAC addresses for the switch. These addresses are static MAC addresses.

mode.

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:
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.
Note
You can also configure MAC aging time in interface configuration mode or VLAN configuration mode.
