Cisco 3550-SMI IOS升级过程分享
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
的
FLASH
上来

Switch#
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。
Switch#dir

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#delete c3500XL-c3h2s-mz-120.5.2-XU.bin

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。
B在switch模式下执行采用xmodem
（很长时间，我试过
39
分钟）
c重启设备
传完后，重新启动就
ok
啦。
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
switch: set
ASSEMBLY_REVISION_NUM=B0
BOOT=c3550-smi.bin
MAC_ADDR=00:04:4D:72:87:C0
MODEL_NUM=WS-C3524-XL-EN错误！未找到图形项目表。
MODEL_REVISION_NUM=A0
MOTHERBOARD_ASSEMBLY_NUM=73-3904-11
MOTHERBOARD_SERIAL_NUM=FAB0445F1YR
POWER_SUPPLY_PART_NUM=34-0851-02
POWER_SUPPLY_SERIAL_NUM=NONE
SYSTEM_SERIAL_NUM=FAA0446W0XD
switch:
b用set命令修改BOOT路径
switch: set boot flash:c3550-smi.bin
switch: set
ASSEMBLY_REVISION_NUM=B0
BOOT=flash:c3550-smi.bin
MAC_ADDR=00:04:4D:72:87:C0

c重新启动OK!
