要在Wireshark中查看NACK(Negative Acknowledgment,否定确认),可以按照以下步骤进行操作:
1. 打开Wireshark并开始捕获数据包。
2. 在过滤器中输入“nack”并点击“应用”按钮,以便只显示与NACK相关的数据包。
3. 查看数据包列表以寻找包含NACK的数据包。您可以单击数据包以查看其详细信息。
4. 在数据包详细信息中,查找“Protocol Details”部分中的“NACK”信息。这将显示NACK的详细信息,如NACK的类型、源地址、目标地址、数据包序号等。
请注意,Wireshark只能显示已捕获的数据包。如果NACK未被记录,则无法在Wireshark中查看。

wireshark configuration Nak是什么报文
Nak报文是指通信中发生错误或失败的情况下,接收方向发送方发送一个否定确认(Negative Acknowledgement)的报文。在Wireshark中,Nak报文通常是指TCP协议中的RST(Reset)报文,它表示连接异常终止或者出现错误。Nak报文也可以在其他协议中出现,比如在USB协议中,Nak报文用于指示数据传输失败。在Wireshark中,可以通过过滤器来查找和筛选特定类型的Nak报文。
