HA System config
8 Optionally change the Unit Priority.
See “Unit Priority” on page 93.
9 If required, select Override master.
See “Override Master” on page 94.
10 Enter and confirm a password for the HA cluster.
11 If you are configuring Active-Active HA, select a schedule.
See “Schedule” on page 94.
12 Select Apply.
The FortiGate unit negotiates to establish an HA cluster. When you select apply you
may temporarily lose connectivity with the FortiGate unit as the HA cluster negotiates.
13 If you are configuring a NAT/Route mode cluster, power off the FortiGate unit and
then repeat this procedure for all the FortiGate units in the cluster. Once all of the units
are configured, continue with “To connect a FortiGate HA cluster” on page 98.
14 If you are configuring a Transparent mode cluster, reconnect to the web-based
manager.
You may have to wait a few minutes before you can reconnect.
15 Go to System > Status.
16 Select Change to Transparent Mode and select OK to switch the FortiGate unit to
Transparent mode.
17 Power off the FortiGate unit.
18 Repeat this procedure for all of the FortiGate units in the cluster then continue with
“To connect a FortiGate HA cluster” on page 98.
To connect a FortiGate HA cluster
Use the following procedure to connect a cluster operating in NAT/Route mode or
Transparent mode. Connect the FortiGate units in the cluster to each other and to
your network. You must connect all matching interfaces in the cluster to the same hub
or switch. Then you must connect these interfaces to their networks using the same
hub or switch.
Fortinet recommends using switches for all cluster connections for the best
performance.
The FortiGate units in the cluster use cluster ethernet interfaces to communicate
cluster session information, synchronize the cluster configuration, and report
individual cluster member status. The units in the cluster are constantly
communicating HA status information to make sure that the cluster is operating
properly. This cluster communication is also called the cluster heartbeat.
