Cisco 6500 error

[james_son]

I have a 6500 connected to 3750 using fiber connection using patch panel.
on the gig port of the 6500 give of error in Input errors, CRC and FRAME

There is no error from the 3750 gigport.

QoS is fine and no drop. it feel like gbit or fiber?

[Reza Sharifi]

Can you try a different fiber patch cord and test again?

HTH

[james_son]

Yes, we replace the fiber from core to patch panel.

i didn't see any error count from the 3750 only from the core

[Reza Sharifi]

Can you try a different port on the 6500?

[james_son]

I'm thinking gbit or fiber but you think it's port itself?

[Reza Sharifi]

It could be the optic, but usually GBIC or SFP, usually you have connectivity or not and if you already have replaced the fiber then I am thinking try a different port and see if you get the results. If you have extra optics you can try a different one

You also may want to clean the fiber tips and the optic and try

Can you post the port config for both switches?

On the 3750-side, post the following output:

1.  sh interface ; and

2.  sh contr e

On the 6500-side, post the output to the command "sh interface ".
