HA System config
Standalone Mode
Standalone mode is the default operation mode. If Standalone mode is selected the
FortiGate unit is not operating in HA mode.
Select Standalone Mode if you want to stop a cluster unit from operating in HA mode.
High Availability
Select High Availability to operate the FortiGate unit in HA mode. After selecting High
Availability, complete the remainder of the HA configuration.
Cluster Members
When the cluster is operating, you can select Cluster Members to view the status of all
FortiGate units in the cluster. Status information includes the cluster ID, status, up
time, weight, and monitor information. For more information, see “To view the status of
each cluster member” on page 95.
Mode
All members of the HA cluster must be set to the same HA mode.
Group ID
The group ID range is from 0 to 63. All members of the HA cluster must have the
same group ID.
When the FortiGate units in the cluster are switched to HA mode, all of the interfaces
of all of the units in the cluster acquire the same virtual MAC address. This virtual
MAC address is set according to the group ID. Table 3 lists the virtual MAC address
set for each group ID.
Active-Active Load balancing and failover HA. Each cluster unit actively processes
connections and monitors the status of the other FortiGate units in the cluster.
The primary FortiGate unit in the cluster controls load balancing among all of
the cluster units.
Active-Passive Failover HA. The primary FortiGate unit in the cluster processes all
connections. All other FortiGate units in the cluster passively monitor the
cluster status and remain synchronized with the primary FortiGate unit.
