To configure a pair of SEs for legacy HA, follow the steps below:

  1. Create an SE group for the pair of SEs. Legacy HA requires each pair of active/standby SEs to be in its own SE group.

  2. Within each SE group:

    1. Add two SEs.

    2. Change the SE group's HA mode to legacy HA.

    3. If applicable, add a floating IP interface.
