Unicast HA heartbeat

Unicast HA heartbeat

In virtual machine (VM) and cloud environments that do not support heartbeat communication with Layer 2 Ethernet frames (see HA heartbeat interface), you can set up a Layer 3 unicast HA heartbeat when configuring HA. This consists of enabling the feature and adding a peer IP address. The peer IP address is the IP address of the HA heartbeat interface of the other FortiGate VM in the HA cluster.

Unicast HA is only supported between two FortiGate VMs in active-passive (A-P) mode. The heartbeat interfaces must be connected to the same network, and the IP addresses must be added to these interfaces.

In the following example, unicast HA heartbeat is enabled over the port3 interface.

To enable unicast HA heartbeat in the GUI:
  1. Go to System > HA.

  2. Enable Unicast Heartbeat and enter the Peer IP, such as 172.30.3.12.

  3. Click OK.

To enable unicast HA heartbeat in the CLI:
config system ha
    set hbdev port3 50
    set unicast-hb enable
    set unicast-hb-peerip 172.30.3.12
end
