CCNA视频：CCNA实验2：备份和还原IOS

 

实验目标：

1：学会通过TFTP服务器备份IOS

2：学会通过TFTP服务器还原IOS

 

实验步骤：

1：使用TFTP服务器备份交换机IOS

2：使用TFTP服务器还原交换机IOS

3：使用TFTP服务器备份路由器IOS

4：使用TFTP服务器还原路由器IOS

 

实验总结：

1：建立交换机和TFTP服务器的通信

sw1(config)#hostnameSW1

 

SW1(config)#interfacevlan 1

SW1(config-if)#ipaddress 192.168.1.1 255.255.255.0

SW1(config-if)#noshutdown

 

测试交换机与TFTP服务器之间的通信：

 

SW1#ping192.168.1.2

Typeescape sequence to abort.

Sending5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:

.!!!!

Successrate is 80 percent (4/5), round-trip min/avg/max = 0/0/3 ms

 

2：备份交换机的IOS

SW1#showflash:

3：还原交换机的IOS

SW1#copytftp: flash:

实验配置二：备份和还原路由器IOS

1：建立路由器和TFTP服务器的通信

R1(config)#interfacefa0/0

R1(config-if)#ipaddress 192.168.1.1 255.255.255.0

R1(config-if)#noshutdown

 

TFTP服务器地址配置 (略)

 

测试路由器与TFTP服务器之间的通信：

R1(config-if)#doping 192.168.1.2

Typeescape sequence to abort.

Sending5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:

.!!!!

Successrate is 80 percent (4/5), round-trip min/avg/max = 0/0/0 ms

 

2:备份路由器的IOS
