Adaptive Forward Error Correction

[HT_JDC]

Hello Experts,

Confirmation for "Adaptive Forward Error Correction (FEC)".

https://docs.fortinet.com/document/fortigate/7.6.4/administration-guide/169010/adaptive-forward-erro...

Is Adaptive FEC only applied to the existing "virtual-wan-link" SD-WAN zone?

I tried it for my created/custom zone which belongs to IPsec tunnel members,

however, it does not seem to work.

FEC counter is not increased at "diag vpn tunnel fec VPN-NAME".

If any, I would like to know the official KB ID and/or the reference.

Any comments are appreciated.

Best regards,

Hello again HT_JDC,

I found this solution. Can you tell us if it helps, please?

Adaptive Forward Error Correction (FEC) is designed to work within the SD-WAN framework, specifically with the "virtual-wan-link" SD-WAN zone. If you are attempting to apply Adaptive FEC to a custom zone that includes IPsec tunnel members and it is not functioning as expected, it may be due to the configuration not aligning with the supported SD-WAN setup.

To troubleshoot this issue, ensure that:

1. The IPsec tunnel is part of the "virtual-wan-link" SD-WAN zone.
2. The FEC profile is correctly configured and applied to the appropriate traffic streams.
3. The SD-WAN health checks and SLA metrics are properly set up to trigger FEC adjustments.
