Symptom

When configuring ethernet over oduflex on NCS4K with GFP mapping and inter-op with third party equipment FCS error is reported on side party side and traffic is down.

Conditions

Configure ethernet over oduflex with gfp mapping and inter-op with third-party equipment.

Workaround

From client Ethernet to OTN trunk ------------------------------------------------ Old implementation (Non-Standard) 1. Stripped the Ethernet Mac Frame FCS 2. Added Gfp payload pFCS(Payload FCS) New implementation (Standard) 1. Forward Ethernet Mac Frame FCS 2. Do not add Gfp payload pFCS(Payload FCS) From OTN Trunk to Client Ethernet ------------------------------------------------ Old implementation (Non-Standard) 1. Stripped Gfp payload pFCS(Payload FCS) if it is present 2. The Ehternet Mac Frame FCS inserted New implementation (Standard) 1. Stripped Gfp payload pFCS(Payload FCS) if it is present 2. Do not insert Ehternet Mac Frame FCS
