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 route
Codes: C - connected, S - static, R - RIP, O - OSPF, OE-OSPF External, M - Management
D - Redirect,
E - IRMP, EX - IRMP external, o - SNSP, B - BGP
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
S 0.0.0.0/0 [1/78125] is directly connected, 1138:18:02, serial0/0
C 21.38.249.4/30 is directly connected, 1138:18:02, serial0/0
C 21.38.250.32/28 is directly connected, 1138:18:36, fastethernet0
C 21.38.250.56/30 is directly connected, 1138:18:37, loopback0
C 22.38.250.32/28 is directly connected, 1138:18:36, fastethernet0
C 22.38.250.56/30 is directly connected, 1138:18:37, loopback1
C 127.0.0.0/8 is directly connected, 1138:18:46, lo0
C 21.38.249.5/32 is directly connected, 1138:18:02, serial0/0
3.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。
LNFS2_WN_AR_01#sh ip interface brief
Interface IP-Address Status Description
gigaethernet0 21.0.225.10 UP LINK TO RG5750
lo0 127.0.0.1 UP
gigaethernet2 unassigned DOWN
gigaethernet3 unassigned DOWN
switchethernet5/0 21.0.227.21 UP
switchethernet5/2 21.0.227.25 UP
serial4/0 21.0.224.34 DOWN TO ShenYang
serial4/1 21.0.229.45 DOWN qingyuan
serial4/2 21.0.229.49 DOWN to Xinbin
serial4/3 unassigned DOWN
null0 unassigned UP
4.查看内存使用情况：sh memory，会出现很多信息，重点查看总使用率如下总使用率为
20.32%
STATISTICS
----------
Used bytes Free bytes Total bytes Used percent
-------------------------------------------
54544868 213885452 268430320 20.32%
5.查看cpu使用率分为三步，第一打开监控cpu命令：spy cpu。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。如下cpu空闲为100%
tDcacheUpd 0026a1e8 5ee99a0 250 0% ( 0) 0% ( 0)
tTunnel 00397a48 55695d0 250 0% ( 0) 0% ( 0)
tCGTask 00737b90 373e6f0 251 0% ( 0) 0% ( 0)
KERNEL 0% ( 0) 0% ( 0)
INTERRUPT 0% ( 0) 0% ( 0)
IDLE 100% ( 185) 100% ( 185)
TOTAL 100% ( 185) 100% ( 185) 6.查看路由器版本信息，同时该命令可以查询到路由器运行的时间如下，该路由器版本为
6.1.25(REL)(integrity)，已经运行的时间为1 week 4 days
LNFS2_WN_AR_01# sh version

7.查看系统日志sh log buff，可以查看路由器记录的日志信息
8.查看设备主控信息sh system mpu
MSTP_LiaoNing#sh system mpu
