新來同事不小心把我的Cisco 2960 24TT 交換機的IOS清了，纔想起了備份另一臺相同型號的IOS
^^^^^^^^^^^^^^^^^^^^^^備份方法^^^^^^^^^^^^^^^^^^^^^^
1.用console和一根直通網線將PC與交換機相連,以com4口爲例.console爲配置而用,網線爲傳輸而用.
2.打開一個超級終端,設置爲默認的連接參數.
3.配置交換機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上安裝WinAgents TFTP Server 4軟件,開啓TFTP服務.並配置PC地址爲同網段即可.
5.備份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 即是我們想要備份的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]?
