1.查看配置命令：sh run作用：查看路由器的配置2.查看路由表sh ip route作用查看路由器的路由表，如下WANGHUA_DANDONGLU#sh ip routeCodes: C - connected, S - static, R - RIP, O - OSPF, OE-OSPF External, M - ManagementD - Redirect,E - IRMP, EX - IRMP external, o - SNSP, B - BGPGateway of last resort is 0.0.0.0 to network 0.0.0.0S 0.0.0.0/0 [1/78125] is directly connected, 1138:18:02, serial0/0C 21.38.249.4/30 is directly connected, 1138:18:02, serial0/0C 21.38.250.32/28 is directly connected, 1138:18:36, fastethernet0C 21.38.250.56/30 is directly connected, 1138:18:37, loopback0C 22.38.250.32/28 is directly connected, 1138:18:36, fastethernet0C 22.38.250.56/30 is directly connected, 1138:18:37, loopback1C 127.0.0.0/8 is directly connected, 1138:18:46, lo0C 21.38.249.5/32 is directly connected, 1138:18:02, serial0/03.简明接口信息查询sh ip interface brif作用：查看各个接口的状态，这里可以看到接口的对应的ip，以及接口状态，up表示接口在使用并且链路正常。

第二步查看cpu情况命令：sh cpu。
第三步，查看完毕后关闭监控：no spy cpu。
