Issue of random recognition of SFP+ coded Extreme on the x620-10x

[AIT_Support]

Two versions of XOS has been tested: 21.1.1.4 patch1-2 and 21.1.1.4 patch 1-5
The Same SFP connected on differents ports displays different errors messages. The interfaces are sometime functional sometime not functional, they are flapping.
The similar SFP modules are functioning on our Production environment without issue.

Hello, all!

For now more often appear issue with DDMI SFP+ of non-original optics.
As with X620-10x, so with X620-16x.

What do you think - is it makes sense to open the case in GTAC?
Or because this is non-original optics there is no any reason?

Thank you!

Hi, There's no real explanation to it, and that just illustrates what is the difference between a generic transceiver and an Extreme one: validation. Nothing has change, but the x620 is - obviously - a different switch, with different interface, different traces length... so maybe this can trigger a problem more often with some 3rd party transceivers?

Hello, colleagues!

Is there any update information about this issue?

Thank you!

I have asked internally about it. I was doubtful this was software related as I never heard of specific change for optic support. Thanks for testing on x460G2.
