1、实验CISCO路由器日常维护和故障诊断时间版本说明修改人2008年4月9日V1.0实验手册开发课程名称:计算机网络工程实验名称:路由器日常维护和故障诊断实验目的：路由器日常维护和故障诊断预备知识：计算机基础知识实验环境：Cisco路由器实验任务任务一：路由器日常维护和故障诊断实验步骤任务一：路由器日常维护和故障诊断　　通常我们使用showinterface命令来查看接口的信息，如showinterfacegig1/0或者showintpos2/0等来分别查看路由器上千兆以太接口和POS接口的端口信息。　　查看以

2、太网接口信息，在cisco上使用命令为：  showinterfacesfastethernet[slot/port-adapter/port]　　查看POS接口信息，在cisco上使用命令为：   showinterfacespos[slot/port-adapter/port]　　1、下例给出了在cisco上查看第1槽位上第1个PA上的第1个快速以太网接口的接口的配置信息：telnet219.142.17.4210001#进入远程路由器Router>en#进入特权模式Router#showinterface
