interface interface-type interface-number: Specifies an outbound interface by its type and number. Description Use mac-address to add or modify a MAC address entry. Use undo mac-address to remove one or all MAC address entries. By default, no MAC address entry is configured in the system. A static or blackhole MAC address entry will not be overwritten by a dynamic MAC address entry. A dynamic MAC address entry can be overwritten by a static or blackhole MAC address entry. If you execute the undo mac-address command without specifying any parameters, this command deletes all unicast MAC address entries and static multicast MAC address entries. You can delete all the MAC address entries (including unicast MAC address entries and static multicast MAC address entries) of a VLAN, or you can choose to delete a specific type (dynamic, static, or blackhole) of MAC address entries only. You can single out certain ports and delete the corresponding unicast MAC address entries, but not the corresponding static multicast MAC address entries. The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC address table entries, however, are lost at next reboot regardless of whether or not you save the configuration. Related commands: display mac-address. Examples # Add a static entry for MAC address 000f-e201-0101. All frames destined to this MAC address are sent out of port GigabitEthernet 1/0/1 which belongs to VLAN 2. system-view [Sysname] mac-address static 000f-e201-0101 interface gigabitethernet 1/0/1 vlan 2 mac-address mac-learning disable Syntax mac-address mac-learning disable View undo mac-address mac-learning disable System view, Layer 2 Ethernet interface view, VLAN view, Layer 2 aggregate interface view Default level 2: System level Parameters None Description Use mac-address mac-learning disable to disable MAC address learning.

Description
Use
mac-address
to add or modify a MAC address entry.
Use
undo mac-address
to remove one or all MAC address entries.
By default, no MAC address entry is configured in the system.
A static or blackhole MAC address entry will not be overwritten by a dynamic MAC address entry. A
dynamic MAC address entry can be overwritten by a static or blackhole MAC address entry.
If you execute the
undo mac-address
command without specifying any parameters, this command
deletes all unicast MAC address entries and static multicast MAC address entries.
You can delete all the MAC address entries (including unicast MAC address entries and static multicast
MAC address entries) of a VLAN, or you can choose to delete a specific type (dynamic, static, or
blackhole) of MAC address entries only. You can single out certain ports and delete the corresponding
unicast MAC address entries, but not the corresponding static multicast MAC address entries.
The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC
address table entries, however, are lost at next reboot regardless of whether or not you save the
configuration.
