CRC errors and input errors on Te 1/2 of Cisco WS-C3560X-48 switch

Hi All,

I am observing CRC errors and input errors on one of the Te1/2 interface of WS-C3560X-48 Cisco switch. I have not observed any CRC errors or input errors on the connected interface at other end. Can you please let us know whether the issue is with cable or SFP module.

 Effected interface:
