Cisco 1131/1242/1252AP从瘦AP升级到胖AP的做法（增加WEB界面）

AIR-LAP1242AG-C-K9, 1242的瘦AP。以1242AP为例，1131和1252做法同样
1、首先准备回退到胖AP的镜像文件。 我拿到的是一个 “c1240-k9w7-tar.124-10b.JA3.tar”的tar包压缩文件。

2、准备TFTP的环境。（建议使用Cisco的TFTP工具，其他的方便易用的也行），把目录指向要升级的镜像目录。

TFTP的服务器主机ip地址设置为10.0.0.2 255.0.0.0 镜象文件改名为“c1240-k9w7-tar.default”(IP地址和镜像文件名这样改从后面的提示中可以知道是为什么)

3、超级终端、控制口连接到AP，以便监控状态。

4、按住ap上的mode键，然后插上电源，稍等一会，出现如下提示

flashfs[0]: 3 files, 2 directories

flashfs[0]: 0 orphaned files, 0 orphaned directories

看到上面wait的提示后，松开mode键

button pressed for 29 seconds

process_config_recovery: set IP address and config to default 10.0.0.1
process_config_recovery: image recovery
image_recovery: Download default IOS tar image tftp://255.255.255.255/c1240-k9w7-tar.default

出现上面提示。（从这里可以看出，在这个状态下，ap把自己的以太口设置为10.0.0.1的ip地址，然后去找tftp服务器下的c1240-k9w7-tar.default镜像文件）

如果上述设置正确的话，就会开始更新了。

5、更新时的屏幕显示如下：

6、到此已经可以了，你等着AP启动完全。你就可以用console口登陆，和配置交换机一样配置；或者配置一个IP address

interface BVI1

ip address 192.168.1.5 255.255.255.0

no ip route-cache

!

ip default-gateway 192.168.1.254

此时就可以登陆WEB界面进行配置。Cisco默认用户密码为Cisco
