【1】.查看交换机引导信息

NST3750#sh boot

BOOT path-list : flash:/c3750e-universalk9-mz.122-55.SE5/c3750e-universalk9-mz.122-55.SE5.bin
Config file : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break : no
Manual Boot : no
HELPER path-list :
Auto upgrade : yes
Auto upgrade path :
NVRAM/Config file
buffer size: 524288
Timeout for Config
Download: 0 seconds
Config Download
via DHCP: disabled (next boot: disabled)

【2】.备份原来的IOS和config.text配置文件

安装一个FTP 服务器，并在交换机上配置FTP的帐号和密码，ip ftp username root 和 ip ftp password root

NST3750#copy flash:/c3750e-universalk9-mz.122-55.SE5/c3750e-universalk9-mz.122-55.SE5.bin ftp:

Address or name of remote host []? 172.16.20.89
Destination filename [c3750e-universalk9-mz.122-55.SE5.bin]?
Writing c3750e-universalk9-mz.122-55.SE5.bin !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

NST3750#copy flash:/config.text ftp:
Address or name of remote host []? 172.16.20.89
Destination filename [config.text]?
Writing config.text !
7964 bytes copied in 0.168 secs (47405 bytes/sec)
NST3750#

【3】.删除交换机IOS目录和文件

NST3750#delete /recursive /recursive flash:c3750e-universalk9-mz.122-55.SE5 ?

*注意：

delete /force(不再询问确认)/recursive(删除目录下的子目录和文件) flash:xxx

如果是flash: (整个flash)，如果是目录，则是整个目录，不要搞错了！

【4】.上传新的IOS tar文件
NST3750#copy ftp: flash:
Address or name of remote host [172.16.20.89]?
Source filename [172.16.20.89/c3750e-universalk9-mz.150-2.SE5.tar]? c3750e-universalk9-mz.150-2.SE5.tar
Destination filename [c3750e-universalk9-mz.150-2.SE5.tar]?
Accessing ftp://172.16.20.89/c3750e-universalk9-mz.150-2.SE5.tar...

57671680 bytes total (12291584 bytes free)

【5】.在交换机中解压tar文件

NST3750#archive tar /xtract c3750e-universalk9-mz.150-2.SE5.tar flash:

c3750e-universalk9-mz.150-2.SE5 (directory)

extracting c3750e-universalk9-mz.150-2.SE5/c3750e-universalk9-mz.150-2.SE5.bin (20416512 bytes) #这个要比较长时间
