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 flashfs[0]: Total bytes: 15998976 flashfs[0]: Bytes used: 1867776 flashfs[0]: Bytes available: 14131200 flashfs[0]: flashfs fsck took 26 seconds.

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
