升级Cisco IOS及备份

接下来升级IOS，这里用到了一个很不错的TFTP SERVER软件，

如何使用我就不说了，往下走

首先去下载到对应的IOS包，我这里使用的是官方的TAR包，所以过程有些不同

# 调试好本地TFTP SERVER，并把IOS包放一起
enable
# dir 先看下剩余空间够不够放，如果不够的，先 erase flash: 清空flash再继续，注意要先备份！
# 解压TAR包到flash中
archive tar /xtract tftp://本地IP地址/TAR包名 flash:
# dir 看下完整带文件夹的bin文件名
# 查看下boot的配置
show boot
configure terminal
# 修改boot的启动为新的IOS
boot system /文件夹名/bin文件名
exit
# 检查boot配置是否是新的IOS
show boot
# 写进去
write memory
# 重启
reload

顺便说下备份

# 调好本地TFTP SERVER
enable
# 查看IOS或配置文件等路径
dir
copy flash tftp
# Source filename：填入需要备份到本地的东西路径
# Address or name of remote host：填本地TFTP SERVER地址
