cisco3550交换机的iso的备份与恢复

1.cisco3550交换机

的iso的备份

首先要保证pc与交换机的物理连接，pc的ip 172.16.1.2 255.255.0.0

172.116.1.1.

在交换机上添加一个vlan 10 并配置ip地址 172.16.1.1

Switch#vlan database

Switch#vlan 10

ccie认证

Switch#end

Switch#conf t

Switch(config)#int vlan 10

Switch(config-if)#ip address 172.16.1.1 255.255.0.0                    

Switch(config-if)#no shut                        

Switch(config-if)#end    

Switch#copy flash:c3550-emi-iso tftp://172.16.1.2

然后填上 ip 和文件名，就开始备份iso了。

不是用命令传的，是点击超级终端的文件传送，然后选择你要导入的IOS文件名，

用XMODEM方式
