Problem to Up port gi 1/1/1 C3KX-NM-1G cisco 3750

[jmanzur1683]

Hi.

This is my problem, I have one cisco 3750x with 24 ports and one C3KX-NM-1G module.

when I connect one gbic sfp-lx in the gi 1/1/1 the port doesnt up.

But when I connect the fiber to another switch the link works.

There are problems with this kind of modules?

regards.

Hi

What do mean by "when I connect one gbic sfp-lx in the gi 1/1/1 the port doesnt up"?

The module is all 1Gig SFP.

Can you clarify?

Maybe the port is in "shutdown" or "err-disable"?

When I connect the fiber to the port module (C3KX-NM-1G) gi 1/1/1 the port doesnt work, and the led are off.

this is the sho interface gi 1/1/1

Have you tried any other GBICs in that slot to see if other known working ones work?   I think you can also run sh int trans det to give you more info if its even being recognized. Do you use the same GBIC and known working cable at the same time?

[Reza Sharifi]

Are you using the correct fiber type  (SM or MM) with the right optics?

Hi Jorge,

Have you tried to swap TX and RX?

Hi, we have about the same problem with a C3560-X and we're tried different SFP's and "fiber-patch-cables", still the module is clean and "dead". We have bought two of this boxes for test and both hace the same problem. It's a "old" module and it can't be the IOS. We're running 150-1.SE2 Universal image.

Hello,

I've had similar problem with WS-C3560X-24T-S and C3KX-NM-1G with original transceiver SFP-GE-L and with replacement transceiver not worked with ASR connected to the other side. Funny is that other side had link up but not my.

Any other vendor devices on the same fiber optics cables with the same SFP transceivers works perfect but not my switch and my module.

The solution was set "speed nonegotiate" on SFP interfaces.

My Catalyst IOS was original 12.2(55)SE8.

Best Regards.
