Introduction to FortiGate-6000 FGCP HA

FortiGate-6000 supports active-passive FortiGate Clustering Protocol (FGCP) HA between two (and only two) identical FortiGate-6000s. You can configure FortiGate-6000 HA in much the same way as any FortiGate HA setup except that only active-passive HA is supported, and even though FortiGate-6000s are configured with VDOMS, virtual clustering is not supported.

You must use the 10Gbit HA1 and HA2 interfaces for HA heartbeat communication. The recommended HA heartbeat configuration is to use a cable to directly connect the HA1 interfaces of each FortiGate-6000 and another cable to directly connect the HA2 interfaces of each FortiGate-6000.

You can use switches to connect the HA heartbeat interfaces. Heartbeat packets are VLAN-tagged and you can configure the VLANs used. If you are using switches you must configure the switch interfaces in trunk mode and the switches must allow the VLAN-tagged packets.

As part of the FortiGate-6000 HA configuration, you assign each of the FortiGate-6000s in the HA cluster a chassis ID of 1 or 2. The chassis IDs just allow you to identify individual FortiGate-6000s and do not influence primary unit selection.

Note

If both FortiGate-6000s in a cluster are configured with the same chassis ID, both chassis begin operating in HA mode without forming a cluster. A message similar to the following is displayed on the CLI console of both devices:

HA cannot be formed because this box's chassis-id 1 is the same from the HA peer 'F76E9D3E17000001' chassis-id 1.

As well, a log message similar to the following is created:

Jan 29 16:29:46 10.160.45.70 date=2020-01-29 time=16:29:51 devname="CH-02" devid="F76E9D3E17000001" slot=1 logid="0108037904" type="event" subtype="ha" level="error" vd="mgmt-vdom" eventtime=1580344192162305962 tz="-0800" logdesc="Device set as HA master" msg="HA group detected chassis-id conflict" ha_group=7 sn="F76E9DT018900001 chassis-id=1"

You can resolve this issue by logging into one of the FortiGates and changing its Chassis ID to 2. When this happens, the two chassis will form a cluster.

Example FortiGate-6000 HA configuration

In a FortiGate-6000 FGCP HA configuration, the primary (or master) FortiGate-6000 processes all traffic. The secondary FortiGate-6000 operates in hot standby mode. The FGCP synchronizes the configuration, active sessions, routing information, and so on to the secondary FortiGate-6000. If the primary FortiGate-6000 fails, traffic automatically fails over to the secondary.
