一 配置C3550的管理地址
配置管理地址的目的是方便把设备上现有的IOS
备份出去以及把新的IOS
传到3550

二备份现有的IOS和配置
在PC
机上运行TFTPserver
，把设备当前运行的IOS
和配置文件上传到PC
机上。 2 -rwx 1645807 Mar 01 1993 01:10:52 c3500XL-c3h2s-mz-120.5.2-XU.bin

三 删除设备上现有的IOS
由于考虑到设备的硬件flash
大小不够，所以要把现有的IOS
删除掉，以便新的IOS
顺利上传到flash
上来。 Switch#

七注意事项：
1路径和目标文件不一致问题
在升级过程中一定要小心，在敲命令行的时候特别要仔细，特别是在改启动路径的时候，如果启动路径的文件和flash
里面的IOS
不相同的话，是启动不了。解决方案 a 在switch模式下，查看系统启动路径的全称
Interrupt within 5 seconds to abort boot process.
The system is unable to boot automatically. The BOOT
environment variable needs to be set to a bootable

2、IOS损坏或者其他导致IOS损坏不能正常启动
如果在升级过程中出现断电或者其他原因导致IOS
没有完全写入flash
中，但是flash
中的旧的IOS
又被删除掉了，解决方案 a只能采用超级终端用Xmodem来把IOS传到设备
只能采用超级终端用Xmodem
来把IOS
传到设备里面去，超级终端的设置采用默认设置就好了。 c重启设备
3启动路径不完全，导致设备不能正常启动
在升级过程中的最后一步，修改启动路径的时候，把路径写错了，比如我们今天就是这样的把本来正确的是 boot system flash:c3550-smi.bin 结果写成了boot system c3550-smi.bin
导致设备不能正常启动。解决方案 a用set命令看设备当前运行的路径
MAC_ADDR=00:04:4D:72:87:C0
MODEL_NUM=WS-C3524-XL-EN
