    话说临近国庆，项目前期眼看瞅着就要接近尾声，用户要在国庆前一天就要搬进新楼，享受空调WIFI美食,
            某公司的采购周期是出了名的长，但无线AP，AC还没到货怎么办？领导坐不住了，急吼吼的问网工：
            小灰啊，这款EWP-WA2610H-FIT 京东上有没有现货？“我查查，还真有”
            “好，没有AC控制器能不能玩的转？” “我来查一查，瘦AP转胖AP是可以行的通的” 
            （我感觉领导这话根本就不是问句啊...理论上可以啊，毕竟小灰以前见过瘦转胖的目录）
            “ 好，明天下午就能到货，还剩一天半时间了。抓紧。” 
            领导另辟蹊径，AP采购的事顺利拿下，下面该我出马了。
    瘦转胖AP容易，网上不有案例吗？
            不容易...
            第一，刚买回来的瘦AP是没有配置的！没有配置的！没有配置的！（重要的话说三遍  ）
            要先通过AC将脚本配置传输到AP。怎么办？还好三期的AC WX3520H还能一用，
            （将一个楼层的交换机其余端口shutdown,释放license的招儿我也想出了）
            说干就干，把AC分配好网段给AP,AP顺利拿到地址，再通过TFTP方式传输倒入胖版本不就搞定了吗？
     (  呵呵，年轻人想法还是简单  )
     一看AP配置傻了，没有TFTP命令！什么，FTP也没有？WTF

    也不看看WX 3520H 是什么货？（采用H3C全新一代Comware V7网络操作系统平台（以下简称V7系统））
    倒入WA 2610H 那是V7版本啊？(so what?) WA2610H V7胖版本没有开发出来！只有V5的，
    所以没有TFTP命令行倒入V5胖版本。
    怎么办？
    华三V7瘦AP转V5胖AP。曲线救国。

  部分重要脚本配置如下：

interface Ethernet1/0/2
port access vlan 1000
port-isolate enable ##端口隔离 2口，3口不能互相访问

dis wlan ap name 模板名字(默认是AP的mac地址) verbose ##查看AP获取的地址

AC:wlan ap-execute 模板名字 exec-console enable ##开启telnet AP的权限

AP的默认password :h3capadmin

V7的H3C AC 3520H版本，下发给H3C EWP-WA2610H-FIT V7版本，
现在要把WA 2610H-FIT AP V7从瘦AP 切到胖AP V5版（H3C WA2610H 胖V7版本没开发出来）

WA2610H

打开设备外壳，里面有一个mini console 口（有个迷你console口，good ）
找到手机usb数据线(即一般手机数据传输充电线) console线就是原来安卓充电器用的那种传输线！
Usb端链接电脑，另一端链接 ap
在电脑上安装驱动

http://www.h3c.com/cn/d_201302/774009_30005_40.htm

驱动安装好后，电脑通信端口会生成一个com口
电脑通过crt登录设备命令行
参考如下文档将v7瘦版本切成v5胖版本

参考案例：
问题现象
某局点现场一台V7的WA4320H-ACN设备，由于现有的AC设备上的license数量不足，需要将AP切换为胖AP使用。了解现场工程师的需求后，我们立即查找相应的资料并查找解决方法。经过查找资料确认该型号的AP胖版本只有V5的版本，所以需要将V7的瘦版本降级为V5的胖版本。
告警信息
经过查找官网软件版本后确认，该型号的AP仅有V5的胖版本
原因分析
该型号V7版本的瘦AP经过查阅资料确认，没有可以使用的V7的相应的适配胖版本，和现场工程师协商建议其将该AP降级为V5的胖AP。
解决办法
引导工程师做V7瘦版本降级V5胖版本的操作，操作过程如下:
在AP的启动过程中

按下Ctrl+B进入AP的BOOTROM菜单

###如果这边不停的格式化，然后重启进入系统，AP就有可能玩坏了。进入到一种貌似是胖AP但console操控不了的局面，貌似就因此玩坏了一个AP..
所以说瘦AP切胖AP真是有风险的！

顺利拿到胖AP就没有坑了吗？
NO WAY .
配置胖AP，先打开无线任务，接入任务，新建SSID等功能子项，注意，密码千万要输正确咯。
绑定射频，开启后发现，安卓手机能用，苹果手机用不了！
为啥？是不是加密方式有问题，
原来是DHCP池没有配DNS，苹果手机跟国产手机不通，没有DNS就认为网络不能用~
以上的坑印象最深，还有就是跳线会接触不良导致传输时断时续，刚开始AP获取IP时端口频繁UP,DOWN是正常的，要有耐心...

这次调AP确实遇到了坑，也怪我无线经验太少，加上又是时间紧张，饭没吃，觉没睡了，现在回想也是酸爽...还好顺利完成任务，回想起来那些坑倒是意犹未尽呐！
