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
Vlan Mac Address Type Protocol Operation Interface
------+-------------------+--------------+-----------+------------+-----------
1 00:00:00:00:00:01 learned 0800 bridging 8/ 1
1 00:d0:95:6a:73:9a learned aaaa0003 bridging 10/23
Total number of Valid MAC addresses above = 2
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.
1 Create VLAN 200, if it does not already exist, using the following command:
-> vlan 200
