- What I did
The port index in port_config.ini should starts from 0, otherwise it will cause xcvrd crash.

What is the definition of the index here? I saw most of the implementation was "front pannel" port number. In such case, it should be "1" based, and we need fix the other side instead.

Hi @zhenggen-xu,
AFAIK it should be 0 based otherwise it will fail the xcvrd.
Could you please provide an example of a "1"-based port_config.ini? I'd like to check.
Thanks.

Looks like this change is specific to fix a platform driver and would like Joe/Guohan to comment. Approving from my side!

My point is the xcvrd should handle both cases, it should probably use the port_config.ini as Source of Truth?

Hi zhenggen,
Thank you for pointing out.
Let's handle the issue on Mellanox-2700-D48C8 for now in this PR and consider a comprehensive solution in the future.

If the indexes are presenting front pannel ports, to fix the error in xvrd, we need reload some of the plugins in your platform code in sonic_platform directory. The changes are fine if the 0 based port index is what you are looking for.

@zhenggen-xu is right. Check out the porting guide here.

https://github.com/Azure/SONiC/wiki/Porting-Guide

index: Physical index of port (optional - needed if ports do not begin with index zero or increment by one), When this column is missing the index starts from 0 and increase by 1 for each row. It is recommend to explicitly set this index column and make the index number match the labeling of the front panel ports. AKA: if the front panel ports are starting from 1, the index should start from 1. If the front panel ports start from 0, the index should start form 0. The break out ports from the same physical port should have same index.
