!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 2/8/33 ms

五、常用路由器状态查询命令(在特权模式下输入命令)
Show version //查看IOS版本号,已启动时间,flash中的IOS的文件名,router里面共有什么的端口,寄存器的值等等。
show protocol //显示与IP 有关的路由协议信息。各个端口的情况。
show flash //查看flash中的内容,IOS的长度,文件名,剩余空间,总空间。
show running-config //查看路由器当前的配置信息。
show startup-config //查看nvram 中的路由器配置信息。
show ip route //查看路由器的路由配置情况
show hosts //查看IP host 表
show interface //查看路由器上的各个端口的状态信息。(很多重要信息)
show controller //查看接口控制器的状态,可看到连接的是DTE还是DCE
show history //查看history buffer 里面的命令列表
六、思考题及其它
⑴ 查看路由器的路由协议信息,用什么命令?
show ip route
