思科模拟 实验十五：路由器的基本配置命令

一、实验目的

掌握路由器的基本配置命令

二、实验描述

主要实验内容如下：

1.配置路由器的名字

2.配置路由器的enable、secret、console、vty的密码

3.接口IP地址的配置及时钟

 三、实验拓扑

四、实验设备            

1.R2811   1台        

2.PC     1台       

五、实验步骤

第1步：配置主机名

Router>enable

Router#config terminal

Route(config)#hostname R1

第2步：配置路由器的密码

R1(config)#enable password jsj1

R1(config)#enalbe secret jsj2

R1(config)#line console 0

R1(config-line)#password jsj3

R1(config-line)#login

R1(config-line)#exit

R1(config)#line vty 0 4

R1(config-line)#password jsj4

R1(config-line)#login

R1(config-line)#exit

R1(config)#service password-encryption

第3步：配置banner信息

R1(config)#banner motd #

Enter TEXT message.  End with the character '#'.

Welcome to jsj414 R1 -Authorized users only.#

验证配置：

Press RETURN to get started!

Welcome to jsj414 R1 -Authorized users only.

第4步：配置接口IP,接口描述及串口时钟

R1(config)#int s1/0

R1(config-if)#ip add 11.1.1.1 255.255.255.0

R1(config-if)#description s1/0 is DCE

R1(config-if)#clock rate 64000

R1(config-if)#no shutdown

验证配置：

R1#show interfaces serial 1/0

Serial1/0 is down, line protocol is down (disabled)

  Hardware is HD64570

  Description: s1/0 is DCE

  Internet address is 11.1.1.1/24

  MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, rely 255/255, load 1/255

  Encapsulation HDLC, loopback not set, keepalive set (10 sec)

  Last input never, output never, output hang never

  Last clearing of "show interface" counters never

  Input queue: 0/75/0 (size/max/drops); Total output drops: 0

  Queueing strategy: weighted fair

  Output queue: 0/1000/64/0 (size/max total/threshold/drops)

     Conversations  0/0/256 (active/max active/max total)

     Reserved Conversations 0/0 (allocated/max allocated)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

     0 packets input, 0 bytes, 0 no buffer

     Received 0 broadcasts, 0 runts, 0 giants, 0 throttles

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

     0 packets output, 0 bytes, 0 underruns

     0 output errors, 0 collisions, 2 interface resets

     0 output buffer failures, 0 output buffers swapped out

     0 carrier transitions

     DCD=down  DSR=down  DTR=down  RTS=down  CTS=down

第5步:配置一个环回接口

R1(config)#int loopback 0

R1(config-if)#ip add 11.2.2.2 255.255.255.0

第6步：保存配置文件

R1#copy running-config startup-config （或R1#write memory）

Destination filename [startup-config]?

Building configuration...

[OK]

第7步：常用的show命令

R1#show ip interface brief

R1#show interfaces

R1#show running-config

R1#show startup-config

R1#show veision
