CRC errors mean that packets have been damaged. This can be caused by a faulty port on the device or a bad Ethernet cable. Changing the cable or apping the port is a relatively easy fix. Occasionally, they are generated on layer 2 by a duplex mismatch. It can also be the result of collisions or a tation transmitting bad data.

What would a normal CRC amount look like, zero or like 20?

The number of CRCs generated or used in a system can vary greatly depending on the specific application and design requirements. There is no "normal" or "acceptable" rate of CRCs as it largely depends on the context of their use.

Selected Answer: C
The metric that confirms a cabling issue is the CRCS (Cyclic Redundancy Check Errors) value. This value indicates the number of packets that failed the CRC check, which is a mathematical algorithm used to detect errors in the data transmitted over the cable. A high number of CRCS errors indicates that there may be a problem with the cabling, such as a loose or damaged cable. In this case, the router interface has recorded 183 CRCS errors, which suggests that there may be a cabling issue that needs to be investigated.

Out of everything on this list, CRCs always will determine an error in function. CRC determines the number of packets received that failed the checksum & are given in the form of receipts on the frame.
