C3KX-NM-10G port not working

[nmdc.kzstan]

Hi,

3560X is connected to another 3560X by 10G fiber optic connection (C3KX-NM-10G network module, SFP-10G-LRM on both ends).

Yesterday 10G port went down. After changing SFPs, cables I am sure one of the 10G ports on network module is not working, it does not work with tested SFPs and cables.

sh inventory command output

What can I try in this situation? Or RMA is the only option?

[Marvin Rhoads]

From how you describe it, an RMA may well be in order. The TAC is pretty good about that sort of thing.

What does "show int te1/1 transceiver detail" show you?

Hi,

What is your IOS?  

Can you also post the output to the command "sh post"?

Try upgrading to 12.2(55)SE9 and try again.

[nmdc.kzstan]

Thank you. Port is up after upgrading.

[Leo Laohoo]

Thanks for taking the time for updating the results.  :)

[Brian Dean]

I'm also having this exact same problem on the same code version. Planning to upgrade this weekend.

[Leo Laohoo]

This thread is >1 year now.  There are newer versions to the 12.2(55)SE train, namely 12.2(55)SE10.  I'd recommend you use whatever latest there is available.

[Brian Dean]

Upgraded to 12.2(55)SE10 with same results. Might try a 15 release but I'm leaning towards a hardware issue on the module. This is a fairly new module installed (<2 months). 

[Brian Dean]

Following up - Cisco sent a replacement module which seems to have resolved my issue.
