由于该端口连接到另一台交换机或HUB,必须继续追查,方法如下:
6509SE> (enable) show cdp nei 3/11
* - indicates vlan mismatch.
# - indicates duplex mismatch.

该命令显示对端设备是一台Cisco2924,假如没有显示,那么说明连接的是别的厂家的设备,可能要到该交换机上用类似的办法继续追查 。
本例子中是Cisco 设备,所有我们可以继续:

通过以上命令可知,MAC地址0009.6b8c.64ec 与Cisco 2924交换机相连,且是该端口上唯一活动的MAC地址,所以IP为10.10.1.250的机器应该就连接在这个端口上 。
