(Optional) Configuring a Static MAC Address Entry

(Optional) Configuring a Static MAC Address Entry

Context

To reduce broadcast traffic and improve network security, you can configure static MAC address entries on the VXLAN-enabled device to specify the forwarding path of BUM packets. This prevents unauthorized users from intercepting data of authorized users.

For packet forwarding in different directions, static MAC address entries are configured in two directions:
  • Configure static MAC address entries on the VXLAN side to specify the VXLAN encapsulation direction when traffic is forwarded from the LAN side to the VXLAN side.

  • Configure static MAC address entries on the LAN side to specify the outbound interface when traffic is forwarded from the VXLAN side to the LAN side.

Procedure

  • Configure a static MAC address entry on the VXLAN side.

    1. Run system-view

      The system view is displayed.

    2. Run mac-address static mac-address bridge-domain bd-id source source-ip-address peer peer-ip-address vni vni-id

      A static MAC address entry of a VXLAN tunnel is configured.

      By default, a static MAC address entry of a VXLAN tunnel is not configured.

  • Configure a static MAC address entry on the LAN side.

    1. Run system-view

      The system view is displayed.

    2. Run mac-address static mac-address interface-type interface-number.subnum bridge-domain bd-id { default | untag | vid vid }

      A static MAC address entry based on a BD is configured.

      By default, no static MAC address entry based on a BD is configured.

Checking the Configuration

Run the display mac-address [ mac-address ] bridge-domain bd-id command to check MAC address entries in a BD.
