Frame errors mean CRC failures on receipt of a frame. The root cause of this could be a bad cable, or a bad interface on either the machine or the switch. Try replacing the cable, then moving to another port on the switch. Share Improve this answer Follow

WebJan 6, 2010 · The CRC error rate is 1.75915% (greater than 1 in a million packets), and the collision rate is less than 0.1%. This can indicate excessive noise or transmission problems on the LAN or the LAN bus itself. A high number of CRCs is usually the result of collisions or a station transmitting bad data. WebApr 10, 2024 · The CRC is generated from the preceding 0 to 4,000 bytes of packet data. For 1200 bps messages the data payload can exceed 4,000 bytes and when this occurs the first CRC will be inserted into the data payload and a second CRC will be started. This CRC will start with data byte number 4,001 and will continue up to 8,000 bytes. The
