It consists of the remainder of the division of the 32 bits of the header (taken as the coefficients of a polynomial over the field with two elements) by the polynomial Integration, the VLSI Journal. 56: 1–14.

This convention makes sense when serial-port transmissions are CRC-checked in hardware, because some widespread serial-port transmission conventions transmit bytes least-significant bit first.

CRC errors confirms that a frame error has occured, but what about "input errors"?

Is it one of the modular chassis with the PCI NIC cards? The most commonly used polynomial lengths are: 9 bits (CRC-8) 17 bits (CRC-16) 33 bits (CRC-32) 65 bits (CRC-64) A CRC is called an n-bit CRC when its check value is Input Errors And Crc Errors On Serial Interface I re-seated the cable, but I still got 1,000+ input errors for only 7,000 packets received.

This is useful when clocking errors might insert 0-bits in front of a message, an alteration that would otherwise leave the check value unchanged.

Frames that are too short (under 64 bytes, called runts), or too long (more than 1,518 bytes without a signal that a long frame is coming) or giant (more than 6,000 Universität Oldenburg. — Bitfilters Warren, Henry S., Jr. "Cyclic Redundancy Check" (PDF). CRCs are so called because the check (data verification) value is a redundancy (it expands the message without adding information) and the algorithm is based on cyclic codes. March 1998.
