Cisco 从瘦AP回退到胖AP(2010-06-08 20:25:21)转载标签:

   公司有几台AIR1242的胖AP,被人升级成瘦AP在用。今天却急需一个胖AP作测试用,一时找不到,只能想办法把其中一台回退到胖AP。网上都是从胖AP升级到瘦AP的资料,问过CISCO,肯定能回退到胖AP,具体方法自己摸索,费了不少功夫,总算回退成功。
   在AP开机时,按住MODE键,一直到状态灯闪琥珀色,系统会有下面的提示:

Unable to get our ip address: no "IP_ADDR" variable set

The system has been encountered and error initializing
tftp file system. The system is ignoring the error and
continuing boot. If you interrupt the system boot process,
the following commands will set IP_ADDR, DEFAULT_ROUTER
and NETMASK environment variables, initializing tftp file
system, and finish loading the operating system software:

   set IP_ADDR
   set DEFAULT_ROUTER
   set NETMASK
   tftp_init
   boot

button is pressed, wait for button to be released...
最后一行的文字,告诉我们松开MODE键就会进入类似init界面

button pressed for 19 seconds
process_config_recovery: set IP address and config to default 10.0.0.1

The system is unable to boot automatically because there
are no bootable files to boot.
AP把自己的以太网接口的IP地址设置成10.0.0.1,因为我在上次启动好后,把FLASH格式化了,所以会提示无法自动启动。

准备好一个AP的IOS镜像文件c1240-k9w7-tar.124-10b.JA3.tar,设置好电脑网卡的IP地址,并启动好TFTP服务器程序。下面是tar命令的参数,
ap: tar ?
usage: tar <-table | -xtract> <tar file> <destination>



用tar -xtract tftp的命令格式:
ap: tar -xtract tftp://10.0.0.2/c1130-k9w7-tar.124-21a.JY.tar flash:
