Symptoms

12.1.1-hf1 only supports module tuning for Source Photonics 100G LR4 optics. It does not support Finisar 100G LR4 optics via f5optics.

Impact

FCS errors may be observed on interfaces using Finisar 100G LR4 optics.

Conditions

This is relevant only if you are running 12.1.1-hf1, and are using Finisar 100G optics.

Workaround

The only workaround is to update the software you are running with an engineering hotfix or software version that supports module tuning for Finisar 100G LR4 optics. Note: This issue applies only to 12.1.1-hf1. This issue is addressed in other versions using a mechanism different from 12.1.1-hf1. For version 12.1.1-hf1, there is an engineering hotfix available to support Finisar 100G LR4 optics.
