Configuring a Static MAC Address Entry

Configuring a Static MAC Address Entry


MAC addresses and interfaces are bound statically in static MAC address entries.

A device cannot distinguish packets from authorized and unauthorized users when it learns source MAC addresses of packets to maintain the MAC address table. This causes network risks. If an unauthorized user uses the MAC address of an authorized user as the source MAC address of attack packets and connects to another interface of the device, the device learns an incorrect MAC address entry. As a result, packets destined for the authorized user are forwarded to the unauthorized user. For security purposes, you can create static MAC address entries to bind MAC addresses of authorized users to specified interfaces. This prevents unauthorized users from intercepting data of authorized users.

Static MAC address entries have the following characteristics:

  • A static MAC address entry will not be aged out. After being saved, a static MAC address entry will not be lost after a system restart, and can only be deleted manually.
  • The VLAN bound to a static MAC address entry must have been created and assigned to the interface bound to the entry.
  • The MAC address in a static MAC address entry must be a unicast MAC address, and cannot be a multicast or broadcast MAC address.
  • A static MAC address entry takes precedence over a dynamic MAC address entry. The system discards packets with flapping static MAC addresses.


  1. Run system-view

    The system view is displayed.

  2. Run mac-address static mac-address interface-type interface-number vlan vlan-id

    A static MAC address entry is created.

  3. Run commit

    The configuration is committed.

Verifying the Configuration

Run the display mac-address static command to check configured static MAC address entries.
