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.
Displaying Address Table Entries
You can display the MAC address table by using one or more of the privileged EXEC commands
described in
Table 7-4 :
Command Purpose

vlan-id Disable MAC address learning on the specified VLAN or VLANs. You
can specify a single VLAN ID or a range of VLAN IDs separated by a
hyphen or comma. Valid VLAN IDs are 1 to 4094. It cannot be an internal
VLAN.
Step 3 end Return to privileged EXEC mode.
Step 4 show mac address-table learning [vlan
vlan-id] Verify the configuration.
