sniffer中文使用说明
以太网帧(数据链路层)格式(总长度64~1518字节=60~1514+4bytesCRC)CRC错误而数据段正常(60-1514)则为一般CRC校验错误CRC准确而数据段lt;60字节,则被称为Runt错误CRC准确而数据段gt;1514字节,则被称为Oversize错误CRC错误且数据段lt;60字节,则被称为Fragment(碎片)CRC错误且数据段gt;1514字节被称为Jabber一个数据帧尾没有构成一个完整的Byte时为alignment错误当产生JAM信号,并呈现Runt/Fragment/CRC错误,为collisionsniffer中文使用说明.ppt
(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.
