system : elbc
Use this command to set the chassis load balancing (ELBC) information for the FortiOS unit. Unit must be in Transparent mode.
A FortiTrunk is a group of backplane slots where the fabric can load balance traffic. In order for this to happen, the trunk members (the blades) are responsible for sending their heartbeats over the fabric channel to the FortiSwitch. If blades are standalone each sends a heartbeat, but if they are in a FGCP HA cluster, only one heart beat is sent and the load balanced traffic is forwarded to the primary HA unit.
config system elbc
set mode {none | content‑cluster | dual‑forticontroller | forticontroller | forti‑trunk | service‑group}
set graceful-upgrade {enable | disable}
set hb-device <intf_name>
set inter-chassis-support {enable | disable}
mode {none | content‑cluster | dual‑forticontroller | forticontroller | forti‑trunk | service‑group}
Select the ELBC mode to use.
none — no ELBC operation
content-cluster — load balance UTM traffic
forticontroller — FortiController
forti-trunk — use the FortiTrunk feature.
service-group — full support of enhanced load balance cluster
graceful-upgrade {enable | disable}
Enable to upgrade the HA cluster when using ELBCv3. It will upgrade the primary unit after first upgrading the other units in the cluster.
hb-device <intf_name>
Specify the heartbeat interface for FortiTrunk mode.
No default.
inter-chassis-support {enable | disable}
Enable or disable content cluster (aka. HAoC) inter-chassis support. When enabled, B1 and B2 on the FSW-5203B will become a static link-aggregate, and will be used as HA hbdevs. FSW-5203B within a chassis cannot use the switch inter-connect as an HA hbdev when "inter-chassis-support" is enabled, and must be connected via B1/B2 instead. Disabling "inter-chassis-support" destroys the link-aggregate and resumes using the switch interconnect as the HA hbdev.
