To reenable MAC address learning, use the mac-address-table learning global configuration command. The command causes the configuration to appear in the show running-configprivileged EXEC command display.

Configuration Examples

This example shows how to disable MAC address learning on VLAN 10:

Router(config)# no mac-address-table learning vlan 10

This example shows how to disable MAC-address learning for all modules on a specific routed interface:

Router(config)# no mac-address-table learning interface GigabitEthernet 0/5

Router(config)#

This example shows how to disable MAC address learning for port-channel interface:

Router(config)# no mac-address-table learning interface port-channel 1

Verification

The following are the examples of the outputs using the show commands.

Router# show mac-address-table

Mac Address Table

-------------------------------------------

Vlan	Mac Address	Type	Ports
----	-----------	--------	-----
20	2222.2222.2222	STATIC	Gi0/2
10	0000.0700.0a00	DYNAMIC	Gi0/9
10	0000.0700.0b00	DYNAMIC	Gi0/1

Total Mac Addresses for this criterion: 3

In the above example, the show mac-address-tablecommand displays both the dynamically and statically learned addresses.

Following is an example for show mac-address-table dynamic command which displays only dynamically learned addresses.

Router#	show mac-address-table dynamic
Mac Address Table

10	0000.0700.0b00	DYNAMIC	Gi0/1
Total Mac Addresses for this criterion: 2

	Following is an example for show mac-address-table vlan 10 command which displays only the
	addresses learned on a particular VLAN/BD.
