[c-nsp] Nexus 3000k (N3K-C3064PQ-10GE) SFP ports "stuck" - Maybe i2c problem?

[Sascha E. Pollok]

Dear People,

I come in peace. But with a problem on a good old N3K-C3064PQ-10GE switch which
works like a charm but got some ports "stuck" with their transceiver information
and I am wondering if anyone experienced that before:

- Ports in the area of 17-23 (roughly) do not update transceiver information. No matter
what I put in, it stays with what it had before (e.g. 10Gbase-SR).
- These ports do not update der link LEDs. If I disconnect a cable or shutdown a port,
the link LED stays green.
- Some of these ports forward traffic on 1G just fine but seem like they are blackholing
traffic for 10G (partially confirmed).

Ports below or above these ports work just fine. Nothing in the logs.

Any special debug commands or ideas to dig deeper? The switch is running
n3000-uk9.6.0.2.U6.9.bin.

Thank you for ideas cheers
Sascha
