The MAC address table configuration tasks include:

Disabling MAC Address Learning 

z 

Configuring the Aging Timer for Dynamic MAC Address Entries 

z 

These configuration tasks are all optional and order independent. You can perform them as needed in 

any order.  

Usually, a device can populate its MAC address table automatically by learning the source MAC 

addresses of received frames.  

To improve port security, you can manually add MAC address entries to the MAC address table to bind 

ports with MAC addresses, thus fending off MAC address spoofing attacks.  

In addition, you can configure blackhole MAC address entries to filter out packets with certain source or 

destination MAC addresses.  

Follow these steps to add, modify, or remove entries in the MAC address table globally:
