海量资料 超值下载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.R2801 1台2.PC 1台3.console线 1根五、实验步骤第1步：配置主机名RouterenableRouter#config terminalRoute(config)#hostname R1配置路由器名字为R1第2步：配置路由器的密码R1(config)#enable password jsj1修改特权模式密码为jinghua1(密码明文显示)R1(config)#enalbe secret jsj2修改特权模式密码为jinghua2(密码加密显示)R1(config)#line console 0进入线路配置模式R1(config-line)#password jsj3配置控制台的密码jinghua3R1(config-line)#login开启密码检查R1(config-line)#exitR1(config)#line vty 0 4R1(config-line)#password jsj4配telnet密码R1(config-line)#loginR1(config-line)#exitR1(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.User Access VerificationPassword:第4步：配置接口IP,接口描述及串口时钟R1(config)#int s1/0R1(config-if)#ip add 11.1.1.1 255.255.255.0R1(config-if)#description s1/0 is DCER1(config-if)#clock rate 64000R1(config-if)#no shutdown验证配置：R1#show interfaces serial 1/0显示接口的详细信息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 0R1(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显示接口的概况R1#show interfaces显示接口的详细信息R1#show running-config显示内存信息R1#show startup-config显示NVRAM配置信息R1#show veision显示系统硬件和软件状态信息六、注意事项1.配置接口地址的时候，一定要注意接口地址的掩码要配置正确，否则无法通信.2.查看接口状态，如果接口是DOWN，通常是线缆故障，如果协议是DOWN，通常是DCE端的时钟频率没有配置.七、参考配置R1#show running-config Building configuration.Current configuration : 868 bytes!version 12.4service password-encryption!hostname R1!enable secret 5 $1$mERr$xQMW9Xa.dxFYe82Wun9dv.enable password 7 082B45400E11101643!ip ssh version 1!interface Loopback0 ip address 11.2.2.2 255.255.255.0!interface FastEthernet0/0 no ip address duplex auto speed auto shutdown!interface FastEthernet0/1 no ip address duplex auto speed auto shutdown!interface Serial1/0 description s1/0 is DCE ip address 11.1.1.1 255.255.255.0 clock rate 64000!interface Serial1/1 no ip address shutdown!interface Serial1/2 no ip address shutdown!interface Serial1/3 no ip address shutdown!interface Vlan1 no ip address shutd
