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#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#int vlan 1

Switch#ping 10.1.27.59
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.27.59, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/3 ms

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
Directory of flash:/

Switch#
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
Delete filename [c3500XL-c3h2s-mz-120.5.2-XU.bin]?
Delete flash:c3500XL-c3h2s-mz-120.5.2-XU.bin? [confirm]
Switch#dir

四上传新的IOS到flash
把新的IOS放在TFTP server的root目录下
Switch#dir 
Directory of flash:/

Switch#copy tftp flash
