Traffic Shaping Profiles are Not Working

[Sadhi_Jayz]

Hi Fortinet Community,

We're facing an issue where traffic shaping on our FortiGate device doesn't seem to be working as expected. Despite setting up the necessary configurations, no traffic appears to be shaped — the system always shows current-bandwidth=0(kbps) when monitoring shaping statistics.

What We’ve Verified So Far:

1. Class IDs are configured correctly.

2. Traffic Shaping Profile is set up and active.

3. Relevant Traffic Shaping Policy is in place.

4. Interface outbound bandwidth is configured.

5. Traffic Shaping Profile is applied to the correct interface.

6. Ran "diagnose netlink interface list" command

No matter what we try, shaping stats show zero usage:

Any help or insights would be greatly appreciated.

Thanks in advance!

Hi,

Please run below debug command and check result.

Hello,

This command does not work because I have configured traffic shaping profiles (class IDs and traffic shaping policies), but no traffic shapers are configured.

Hi Sadhi Jayz,
What is version running on the box?

[Sadhi_Jayz]

Hello Harry,

The device is a FortiGate-601F running firmware version v7.6.2, build 3462 (Feature Release).

Hi Sadhi,

Can you share some more information about your network?

• What is the policy for the sessions? Can you share the session output? dia sys session list
• Can you snapshot the current bandwidth of the outgoing interface where you set QoS?
• Can you share the configuration of QOS configure ?

If you can, please share it through my official email: bhoang@fortinet.com.

Regards

Bill

The profile needs to be attached to the interface and the interface needs a bandwidth estimate but that's not the "estimated bandwidth" where you set it. That's just for reports. "outbandwidth needs to be set either via CLI or further down in the GUI

Hi bokelsu1,

I have already applied the interface outbound bandwidth and traffic shaping profile.

I was going to create basically the same topic, the Fortigate tool, Traffic Shaping Profiles, is also not working on my firewall.
These are the configurations made:

Traffic Shaping Profile

Traffic Shaping Policy

I

In my case the equipment is 100F version v7.4.3 build2573 (Feature)

And apparently the Traffic Shapers(Shared shaper, Reverse shaper and Per-lP shaper) rules work

Hi UniMK

Can you use only Shaping Profile to make a test ?
