WebMay 21, 1999 · If the traffic rate is very low, the rate of CRC errors may be lower still; 2) Management entities counting CRC errors may not easily associate CRC errors with specific links. A link may consist of a multiple link segments. Each segment may contain "good" or "bad" media and even different media types due to media conversion.
