This example shows how to configure the Layer 3 interface on slot 7, port 3 with a static MAC address:
switch# config t
switch(config)# interface ethernet 7/3
switch(config-if)# mac-address 22ab.47dd.ff89
switch(config-if)#
Configuring the Aging Time for the MAC Table
You can configure the amount of time that a MAC address entry (the packet source MAC address and port
on which that packet was learned) remains in the MAC table, which contains the Layer 2 information.
