cisco6509 CatOS 转为Native IOS过程

钱塘在线

引擎：WS-SUP720-3B 主备各一块

线路卡：WS-X6148X2-45AF 五块。

Cio CompactFlash Memory Card, 128 MB 2块。

该设备原为cio 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:
IP 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
127893504 bytes available on device disk0, proceed (y/n) ? y

Loading s72033-advipservicesk9_wan-mz.122-18.SXF.bin

File disk0:s72033-advipservicesk9_wan-mz.122-18.SXF.bin checksum verifd and is Ok.
File has been copd successfully.
SWITCH_1> (enable) dir disk0:
2 -rw- 76599844 Sep 17 2005 09:52:11 s72033-advipservicesk9_wan-mz.122-18.SXF.bin

51290112 bytes available (76603392 bytes used)

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 specifd 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
auto-config: non-recurring, overwrite, sync disabled
ROMMON console baud: 96
