Overview
NPM can monitor CRC (cyclic redundancy check) Errors in Cisco devices using a Universal device poller. A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached based on the remainder of a polynomial division of their contents.
