Configuring ECN for managed FortiSwitch devices

Explicit Congestion Notification (ECN) allows ECN enabled endpoints to notify each other when they are experiencing congestion. It is supported on the following FortiSwitch models: FS-3032E, FS-3032D, FS-1048E, FS-1048D, FS-5xxD series, and FS-4xxE series.

On the FortiGate unit that is managing the compatible FortiSwitch unit, ECN can be enabled for each class of service (CoS) queue to enable packet marking to drop eligible packets. The command is only available when the dropping policy is weighted random early detection. It is disabled by default.

To configure FortiSwitch to enable ECN packet marking to drop eligible packets:

config switch-controller qos queue-policy

edit "ECN_marking"

set schedule round-robin

set rate-by kbps

config cos-queue

edit "queue-0"

set drop-policy weighted-random-early-detection

set ecn enable

next

edit "queue-1"

next

edit "queue-2"

next

...

end

next

end
