Sample MAC Address Table Configuration
The following steps provide a quick tutorial that will create a static MAC address and change the MAC
address aging timer for VLAN 200:
Note.
Optional.
Creating a static MAC address involves specifying an address that is not already used in
another static entry or already dynamically learned by the switch. To determine if the address is already
known to the MAC address table, enter
show mac-address-table
. If the address does not appear in the
show mac-address-table
output, then it is available to use for configuring a static MAC address entry. For
example,
-> show mac-address-table
Legend: Mac Address: * = address not valid

The
show mac-address-table
command is also useful for monitoring general source learning activity and
verifying dynamic VLAN assignments of addresses received on mobile ports.
