简介
本文档介绍有关Catalyst 9800历史事件列表的快速参考。
结构
利用9800平台的永远在线日志记录功能，您可以快速轻松地列出特定类型的事件，前提是您知道特定的日志行是什么样子的。
本文围绕“show logging profile wireless”命令的使用，这个命令主要经过所有与无线相关的二进制日志（这些日志始终打开，即使没有启用任何形式的活动调试）。
“start last <time period>”允许返回至日志中的特定时间段。
如果不使用管道限制搜索，该命令将在终端上输出大量数据，这就是所有示例使用具有特定事件的管道的原因。
客户端
列出特定时间内AP从特定客户端收到的关联请求：
myc9800-CL#show logging profile wireless start last 1 hour filter mac 9418.6548.6fb1 | i Association received | MY_AP
2024/07/30 08:55:58.981172447 {wncd_x_R0-0}{1}: [client-orch-sm] [19389]: (note): MAC: 9418.6548.6fb1 Association received.

列出已成功进行身份验证的客户端：

噪声和干扰值
这需要设置“set platform software trace wireless chassis active r0 rrm rrm-client-dca info”以在日志中显示信息：
