No traffic on TenGig Interface but Input errors and CRC Increasing

[Muhammad Hamid Ashraf]

Dear All,

Please see below the output from my ASR 9K TenGig Interface. Strange thing is that this interface is taken out of production Bundle and there is no traffic on it BUT the input errors and CRC is increasing continously:

Note: This interface is an uplink to service provider and at their end they are not seeing any such errors.

You need to get this link checked out.  The SFP+ look so terrible I'm beggining to think it's a module that's failing.
