小灰的网工日常之华三瘦转胖AP,我与华三的又一段孽缘呀~~~
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 :h4capadmin
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.h4c.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

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!
