10GB-T module (C3KX-NM-10GT) issue on 3750 stack Part 2

Travis Ryan

I bought the 10GB-T module (C3KX-NM-10GT) for 3750x stack. Asked the support community here what IOS version I should update my stack to because when I installed the module I saw 2 10gb ports for each stack member, not just 2 10gb ports for my last stack member. The response I got was basically any version 15.0.1 and higher. Reference ( )

I finally got around to updating my stack to 15.0.2 se6 and whoa nellie was it a painful upgrade. But I got it done, started my stack without the module. Everything looked fine. Shut the stack down, put the module in, started the stack back up. I saw eight 10gb ports again. Shut down my stack, took the module out, restarted my stack, still saw the 10gb ports, shutdown my stack, put the module back in, restarted my stack. Eight 10gb ports are still there. What's next to try and get this module actually working?

OK, if you upgrade to the proper code and you still have issue with the module, I suggest you open a ticket with Cisco TAC and bring this issue to their attention.

Hmm, I recall having "ghost" 10g ports, or even "ghost" 1g SPF ports is often normal on a 3750 for its other SPF module cards.
