MAC address entries are classified into the following types:

Blackhole MAC address entries: They are used to discard packets with specified source or destination MAC addresses. Blackhole MAC address entries are configured by users and will not be aged.
Static MAC address entries: They are configured by users and will not be aged.
Dynamic MAC address entries: They are configured by users or obtained by learning source MAC addresses. The entries will be aged.

To delete the previous MAC address entries, you can run the following commands.

The undo mac-address all vlan command deletes all the VLAN-based MAC address entries.
The undo mac-address all interface-type interface-number command deletes all the port-based MAC address entries.
The undo mac-address all interface-type interface-number vlan command deletes all the port-based and VLAN-based MAC address entries. The interface specified in interface-type interface-number must reside in the VLAN specified in vlan. To delete the MAC address entries successfully, you must create the VLAN first.
If no parameter is specified, all the MAC entries of the system are displayed.
