(Ethernet frame (data link layer) format (total length 64~1518 bytes = 60~1514 4bytesCRC) CRC error and data segment normal (60-1514) is a general CRC check error CRC is accurate and data segment lt; 60 bytes, it is called Runt error CRC is accurate and the data segment gt; 1514 bytes, it is called Oversize error CRC error and data segment lt; 60 bytes, it is called Fragment (fragment) CRC error and data Segment gt; 1514 bytes are called Jabber. When a data frame end does not form a complete Byte, it is an alignment error. When a JAM signal is generated, and a Runt/Fragment/CRC error is presented, it is collision.
