[c-nsp] Input errors between PE - P

[Kike]

Hi,

Here is the picture: two multimode direct fibers between PE - P

We are trying to figure out what is causing these erros. No physical
issue, we changed both fibers and Gbics...
Here are the "sh int" outputs:

There are lots of input errors just in the P interfaces... we are
running out of ideas about what is going on...

Thanks,
