You can enable High Availability (HA) on a pair of Edges to ensure redundancy.

  1. In the Enterprise portal, click Configure > Edges.
  2. Select the SD-WAN Edge from the list and click the Device tab.
  3. Scroll down to the High Availability section and click Active Standby Pair.

By default, the HA interface to connect the pair is selected as follows:

  • For Edges 520, 520v, and 540: The LAN1 port is used as HA interface and DPDK is not enabled on these platforms.
  • For Edges 510, 610, 620, 640, 680, 840, 2000, 3400, and 3800: The GE1 port is used as HA interface and DPDK is enabled on these platforms.
Note: The above HA interfaces are selected automatically and you cannot configure an HA interface manually.
