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。
