snmp counter ifInErrors(  always shows zero, even if displaying interface shows diferent value:

Alarm Information
Handling Process
I've checked the MIB reference and i saw that customer used wrong OID.
The correct tree is :

               being deliverable to a higher-layer protocol.  For

               character-oriented or fixed-length interfaces, the

               number of inbound transmission units that contained

               errors preventing them from being deliverable to a

Root Cause
