新来同事不小心把我的Cisco 2960 24TT 交换机的IOS清了，才想起了备份另一台相同型号的IOS
^^^^^^^^^^^^^^^^^^^^^^备份方法^^^^^^^^^^^^^^^^^^^^^^
1.用console和一根直通网线将PC与交换机相连,以com4口为例.console为配置而用,网线为传输而用.
2.打开一个超级终端,设置为默认的连接参数.
3.配置交换机IP.
C2-3-2>enable
C2-3-2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
C2-3-2(config)#int vl 1
C2-3-2(config-if)#ip address 58.30.213.180 255.255.255.224
C2-3-2(config-if)#no shutdwon
C2-3-2(config)#ip default-gateway 58.30.213.161
4.PC上安装WinAgents TFTP Server 4软件,开启TFTP服务.并配置PC地址为同网段即可.
5.备份IOS
C2-3-2#show version
System p_w_picpath file is "flash:c2960-lanbase-mz.122-35.SE5/c2960-lanbase-mz.122-35.
SE5.bin"
c2960-lanbase-mz.122-35.SE5/c2960-lanbase-mz.122-35.SE5.bin 即是我们想要备份的IOS
C2-3-2#copy flash: tftp:
Source filename [c2960-lanbase-mz.122-35.SE5/c2960-lanbase-mz.122-35.SE5.bin]?
Address or name of remote host []? 58.30.213.169
Destination filename [c2960-lanbase-mz.122-35.SE5.bin]?
