思科路由器里查看此接口是DCE还是DTE端的命令是什么?

我记得貌似是 show controllers 然后接个端口? 但是出来是一大堆东西不知道在哪里看,各位帮帮忙,最好带截图呵呵,我用的是Packet Tracer 这个模拟器

show controllers 接口名 并不是完全真实的反映 DCE或 DTE例如,如果你使用的是Dynamips ,使用IOS时,当时输入上述命令,在串口线的两端都显示的是
cable type : V.11 (X.21) DCE cable, received clockrate 2015232所以根本无法判断哪一段是DCE。事实上,在串行线的两端分别输入命令:show interface 接口名会出现下面两行结果: LMI enq recvd 19, LMI stat sent 19, LMI upd sent 0, DCE LMI up
LMI enq sent 34, LMI stat recvd 35, LMI upd recvd 0, DTE LMI up 才显示一个是DCE ,一个是DTE。
