Chapter 7 Administering the Switch

Managing the MAC Address Table

Beginning in privileged EXEC mode, follow these steps to disable MAC address learning on a VLAN:

To reenable MAC address learning on a VLAN, use the default mac address-table learning vlan
vlan-id
global configuration command. You can also reenable MAC address learning on a VLAN by
entering the mac address-table learning vlan vlan-id global configuration command. The first
(default) command returns to a default condition and therefore does not appear in the output from the
show running-config command. The second command causes the configuration to appear in the show
running-config
privileged EXEC command display.

This example shows how to disable MAC address learning on VLAN 200:

Switch(config)# no mac

a

ddress-table learning vlan 200

You can display the MAC address learning status of all VLANs or a specified VLAN by entering the
show mac-address-table learning [vlan vlan-id] privileged EXEC command.
