Base backplane HA configurations |
To configure HA interface failover to use two FortiSwitch boards
1Insert the FortiSwitch boards into chassis hub/switch slot 1 and hub/switch slot 2.
If you want to form an HA cluster between FortiGate boards in separate chassis, link the base backplanes of each chassis by connecting FortiSwitch boards front panel base or ZRE interfaces with an Ethernet cable.
For example hardware installations, see Figure 23 on page 69, Figure 24 on page 70, Figure 25 on page 70, and Figure 26 on page 71.
2Insert FortiGate boards into the required chassis slots.
3On each FortiGate board to be included in the HA cluster, go to System > Config > HA.
4Select the HA Mode, then enter the Group Name, and Password.
5Set other HA options as required.
6Configure the base backplane interfaces as heartbeat interfaces.
7Set the priority of the base backplane interfaces to be higher than the priority of all other interfaces so that they are selected as the primary and first failover heartbeat interfaces.
Note: Heartbeat interface precedence can be determined by multiple factors, including Priority and position in the Heartbeat Interface list. For details, see “Slot position and HA heartbeat interface precedence” on page 77.
•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 interfaces 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.
8If you want to select a different base backplane interface as the primary heartbeat interface, increase its priority.
9Select OK.
One FortiSwitch board per chassis
Installing a single FortiSwitch board provides a single base backplane HA heartbeat and synchronization channel.
Note: More than one cluster can use the same base backplane channel for HA communication. To separate HA communications of multiple clusters using the same channel, configure a different HA Group Name and Password for each cluster.
Unlike hardware configurations involving two FortiSwitch boards per chassis, when installing only one FortiSwitch board per chassis, the slot position of the FortiSwitch board becomes an important consideration. A single FortiSwitch board should usually be installed in hub/switch slot 1 for
