Prerequisites

This section describes HA requirements that must be met before configuring a SD-WAN Edge as a Standby.

• The two SD-WAN Edges must be the same model.
  Note: Mixing Wi-Fi Capable and Non-Wi-Fi Capable Edges in High Availability Is Supported in Release 5.4.0 and later.

  Beginning in 2021, VMware SD-WAN introduced Edge models which do not include a Wi-Fi module: the Edge models 510N, 610N, 620N, 640N, and 680N. Prior to Release 5.4.0, deploying a Wi-Fi capable Edge and a Non-Wi-Fi capable Edge of the same model (for example, an Edge 640 and an Edge 640N) as a High-Availability pair was not supported. With Release 5.4.0, this combination is supported and the customer can deploy Edges of the same model number with different Wi-Fi capabilities.

• Only one SD-WAN Edge should be provisioned on the SASE Orchestrator.

• The Standby SD-WAN Edge must not have an existing configuration on it.

• Ensure not to use 169.254.2.x for management interface.
