注释:

Image boots up and console user presented with CLI prompt

镜像启用,进入命令行界面
 

 

6500的IOS二进制文件保存在SP的bootflash中。SP的bootflash在IOS命令行中使用sup-bootflash:表示,在rommon模式使用bootflash:表示。
IOS镜像同样可以保存在CF卡中(用disk0: disk1:表示),从CF中启动IOS镜像
NVRAM用于保存配置文件,不用于保存镜像文件
 
sup-bootflash:中的一个单独的镜像文件其实包括两个镜像 —— 一个SP使用,一个RP使用
1.IOS镜像文件的SP部分被解压、加载到SP的内存中
2.SP从解压加载到SP内存中的镜像中启动
3.一旦SP完成启动过程,将控制权交给RP,IOS镜像文件的RP部分被解压、加载到RP的内存中
(注意到RP的bootflash中并没有镜像文件,RP从SP的bootflash中的镜像中启动)
4.RP从解压加载到RP内存中的镜像中启动
