cisco6509 转换为Native IOS实际过程

引擎：WS-SUP720-3B 主备各一块

线路卡：WS-X6148X2-45AF 五块。

Cisco CompactFlash Memory Card, 128 MB 2块。

该设备原为cisco ios模式，但因当时IOS不支持WS-X6148X2-45AF 线路卡所以采用CatOS模式以支持上述线路卡,后思科推出支持的IOS版本s72033-advipservicesk9_wan-mz.122-18.SXF.bin，客户要求再次改为IOS版本。此两块 CompactFlash Memory Card曾在原IOS模式下格式化过，在此次升级过程中两种模式下（catos和IOS）竟都能写入。以下为升级过程：

1。首先将备份引擎拔下（支持热插拔），在catOS下将IOS映象文件拷入CompactFlash Memory Card 中。因IOS大小为70多兆所以用TFTP无法传也不可靠，所以用FTP传输，输入set ftp username；set ftp password 设置好调用的FTP用户名和密码。执行：

SWITCH_1> (enable) copy ftp disk0:

P address or name of remote host <172.21.239.40>?

Username for ftp?

Password for User ftp<>:

Name of file to copy from ? s72033-advipservicesk9_wan-mz.122-18.SXF.bin

SWITCH_1> (enable) dir disk0:

2。查看当前交换机启动变量。寄存器值为0x2102,下一步将修改此值为0x0

SWITCH_1> (enable) sh boot

BOOT variable = bootflash:cat6000-sup720cvk8.8-4-3.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg

Configuration register is 0x2102

ignore-config: disabled

auto-config: non-recurring, overwrite, sync disabled

ROMMON console baud: 9600

boot: image specified by the boot system commands

Image auto sync is enabled

Image auto sync timer is 120 seconds

3.修改寄存器值为0x0

SWITCH_1> (enable) set boot config-register 0x0

Configuration register is 0x0

ignore-config: disabled

ROMMON console baud: 9600

boot: the ROM monitor

4。确认此值已修改，并reset。

SWITCH_1> (enable) sh boot

BOOT variable = bootflash:cat6000-sup720cvk8.8-4-3.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg

Configuration register is 0x0

ignore-config: disabled

　　auto-config: non-recurring, overwrite, sync disabled

　　ROMMON console baud: 9600

　　boot: the ROM monitor

　　Image auto sync is enabled

　　Image auto sync timer is 120 seconds

　　SWITCH_1> (enable) reset

　　5。系统重启进入ROMMON模式。输入SET查看环境变量。
