cisco ap 1200 升级IOS 实战原创

升级AP IOS的时候 不小心灌了一个IOS 导致 不断的重启。。大概是内存不够吧，怎么办？虽然还能回到ap#模式下，但是仅仅在5，6秒的时间内就会自动重启动，我把灌进去的IOS给delete 了。。原来的IOS 在灌新的IOS 的时候 因为空间的原因 所以也早就delete 了。。所以里面等于是根本没有IOS 了，结果boot 后 回到了 类似router 的rommon> 模式下，当然在AP 上 是 “ap：" 模式下

ap：

问了一下命令
ap: ?
          ? -- Present list of available commands
      arp -- Show arp table or arp-resolve an address
       boot -- Load and boot an executable image
      cat -- Concatenate (type) file(s)
clear_ether -- clear ethernet port statistics
       copy -- Copy a file
   delete -- Delete file(s)
      dir -- List files in directories
dump_save_regs -- dump saved regs in OCM
   etest -- test emac driver code
   ether_init -- initialize ethernet port
   flash_init -- Initialize flash filesystem(s)
   format -- Format a filesystem
       fsck -- Check filesystem consistency
       help -- Present list of available commands
init_pci -- initialize pci bridge
led_test -- cycle led patterns
   memory -- Present memory heap utilization information
   mkdir -- Create dir(s)
       more -- Concatenate (display) file(s)
       read -- read at address
   rename -- Rename a file
-- MORE --
   reset -- Reset the system
   rmdir -- Delete empty dir(s)
      set -- Set or display environment variables
set_baud -- set baud rates
set_sleep -- Pause (sleep) for a specified number of seconds
   show_ether -- show ethernet port statistics
show_pci -- show pci setting
switch status -- report push button switch status
      tar -- extract or listing a tar file
test ram -- read at address
tftp_init -- Initialize tftp file system
       type -- Concatenate (type) file(s)
   unset -- Unset one or more environment variables
    version -- Display boot loader version
   write -- write at address

发现 有set的指令，逐如下配置，和router 上类似

配置ip 地址
ap: set IP_ADDR 1.1.1.1     (配置ap本地地址)
ap: set NETMASK 255.255.255.0
ap: set DEFAULT_ROUTER 1.1.1.2 (tftp address)

ap: tftp_init

ap: BOOT=tftp://1.1.1.2/c1200-k9w7-mx.123-2.JA

这时候你可以看看set 的情况

ap:set

BOOT=tftp://1.1.1.2/c1200-k9w7-mx.123-2.JA
DEFAULT_ROUTER=1.1.1.2
ENABLE_BREAK=yes
IOS_STATIC_IP_ADDR=1.1.1.1
IOS_STATIC_NETMASK=255.255.255.0  
IP_ADDR=1.1.1.1
MANUAL_BOOT=no
NETMASK=255.255.255.0


然后手动的boot
ap:boot

嘿嘿，虽然和router 在roomon> 模式下类似。。但是实战中一下子遇到 一时间还真有点 冒汗...客户在边上看着呢。。



其实一开始 因为还能回到ap＃ 模式下的，只是由于时间太短，仅仅5秒的时间 就会重启动，所以一时间没想到用tftp 去load IOS

以后可以在 记事本上编辑这样的命令 就可以了
