前言
本文为点对点协议( )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。
硬件和软件版本
- 此配置是可适用的对所有Cisco IOS软件版本。
- DCE边用广域网DCE电缆连接。
- DTE边用广域网DTE电缆连接。
欲知关于广域网DCE/DTE电缆的更多信息参见 串行电缆 说明文件。
网络图
本文根据以下配置：
在此配置， Prasit作为DCE和 icey是DTE。
配置
interface Serial0 ip addre 5.0.2.1 255.255.255.0 enca ulation clockrate 64000 no cdp enable
interface Serial1 ip addre 5.0.2.2 255.255.255.0 enca ulation no cdp enable

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 icey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。
prasit#show controllers serial 0
