备份IOS文件

实验目的:

学习如何备份IOS文件

学习TFTP软件如何使用

实验说明:

升级IOS的过程同备份IOS过程类似

注意PC与路由器的UTP线的类型,

实验拓扑图:

基本配置:

Router#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)#hostname test_router

test_router(config)#int Fa0/0

test_router(config-if)#ip address 192.168.10.1 255.255.255.0

test_router(config-if)#no shut

 

PC IP:    192.168.10.2

子网掩码: 255.255.255.0

网关:     192.168.10.1

PC要安装TFTP服务器端软件,此实验使用3Cdeamon软件

实验步骤:

1. 测试网络联通性

test_router#ping 192.168.10.2

 

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.10.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

test_router#

2. 启用TFTP服务器:

4. 备份IOS:

test_router#sh flash:

 

System flash directory:

File  Length   Name/status

  1   7754580  c2600-i-mz.123-26.bin  

[7754644 bytes used, 633964 available, 8388608 total]

8192K bytes of processor board System flash (Read/Write)

 

 

test_router#copy flash: tftp

Source filename []? c2600-i-mz.123-26.bin

Address or name of remote host []? 192.168.10.2

Destination filename [c2600-i-mz.123-26.bin]?

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

7754580 bytes copied in 55.34 secs (140992 bytes/sec)

结束后可以到D盘下查看备份的文件

5.实验完成
