本文为点对点协议(PPP)背对背连接提供示例配置。 您能使用它验证您的连接和硬件适当地运作。
欲知关于广域网DCE/D TE电缆的更多信息参见 说明文件。
本文根据以下配置:
在此配置, Prasit作为DCE和Spicey是DTE。

show命令
使用以下show命令测试您的网络适当地运行:
show controllers
ping
show interfaces serial x
如下所示的输出是输入这些命令的结果在我们在此示 例配置使用的设备。
我们能使用 show controllers命令表示, Prasit是DCE和Spicey是DTE。 此命令提供您信息物理层是否 工作并且什么类型的电缆连接。
