FortiGate-5140 and 5050 base backplane communication

Base backplane HA configurations

If interface priorities are not all equal, set the base backplane interface priority to a higher value than all other interfaces.

If interface priorities are all equal, set the base backplane interface priority to a higher value than all other interfaces, or disable interfaces listed above the base backplane interface in the Heartbeat Interface list. For some FortiGate models, FortiSwitch slot positions, or configurations of other HA interfaces, this may mean that no change is required.

8Select OK.

Choosing the slot position

Depending on the types of communications, HA or other, that you want to pass through the base channels, you may choose to install FortiSwitch boards in different slots: base hub/switch slot 1, base hub/switch slot 2, or both.

When using FortiSwitch boards to provide a network connection to the base channels, hub/switch slot position does not matter. However, you can improve robustness by installing FortiSwitch boards in both slots and providing a redundant link.

For all types of communication, using both slots has the advantage of improving reliability of communications through or to the base backplane because no FortiSwitch is a single point of failure. Using both slots also provides the option of separating multiple sensitive or high volume communications, such as HA communications for multiple clusters.

Note: For HA configurations, you can further improve fault tolerance by adding one or more non-base backplane interfaces as heartbeat interface failovers.

However, if you install only one FortiSwitch board, in addition to fault tolerance considerations, the slot position has additional effects specific to HA.

Inter-chassis HA configurations require that the switch use the same slot number in each chassis so that each cluster member’s configuration uses the same heartbeat interface.

Slot position affects HA heartbeat interface selection and failover order.

Slot position and HA heartbeat interface precedence

When installing only one FortiSwitch board with an HA cluster of FortiGate-5001A or FortiGate-5005FA2 boards, it is usually preferable to use hub/switch slot 1. This allows you to connect one or more of the other FortiGate-5001A or FortiGate-5005FA2 interfaces as backup HA heartbeat interfaces.

The preferred FortiSwitch board slot is different for FortiGate-50051SX and FortiGate-5001FA2 board HA clusters. In this case, it is usually preferable to use hub/switch slot 2.

The reason for selecting different slots is related to the mechanism for heartbeat interface selection, which is indirectly tied to slot number.

During heartbeat interface selection, the heartbeat interface with the highest priority is selected first. If multiple heartbeat interfaces have highest priority, including when all have equal priority, the HA cluster chooses a heartbeat interface using the Heartbeat Interface list.
