HA active-passive cluster setup

An HA Active-Passive (A-P) cluster can be set up using the GUI or CLI.

This example uses the following network topology:

To set up an HA A-P cluster using the GUI:
  1. Make all the necessary connections as shown in the topology diagram.
  2. Log into one of the FortiGates.
  3. Go to System > HA and set the following options:



    Device priority

    128 or higher

    Group name


    Heartbeat interfaces

    ha1 and ha2

    Except for the device priority, these settings must be the same on all FortiGates in the cluster.

  4. Leave the remaining settings as their default values. They can be changed after the cluster is in operation.
