Administering the Switch
Beginning in privileged EXEC mode, follow these steps to disable MAC address learning on a VLAN:
Command
Step 1
configure terminal
Step 2
no mac address-table learning vlan
vlan-id
Step 3
end
Step 4
show mac address-table learning [vlan
vlan-id]
Step 5
copy running-config startup-config
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
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
