HP Access Point 420多SSID多Vlan的配置
公司使用的Wirless为HP AP420.
Boss要求公司内部人员使用wireless可以进入公司内网，查看公司文件服务器；来宾使用的wireless只可以上internet，不可以进入公司内部。
由于公司早已有驻厂的外部人员，已划vlan 197给外部人员使用，和我公司内部网络隔离。（这里就不阐述了）
现在就是要在AP上设置了。
由于HP AP 420支持UI，所以我们先在那里将新的SSID设置好。
进入HP AP 420，找到Wireless interfaces，
选择Add new SSID
Index 选择（总共有6个信道）
SSID Name：（自己按规划填写）
SSID Description ：（简单描述就行）
VLAN ID:（就是你要设置的vlan在路由器或者交换机上）
Vlan Tagging ：（这个一定要选择Enable）
然后点击Apply Changes。
另外在路由器或交换机上一定要将连接AP的端口修改为（Taaged口或者Trunk口），因为马上你的AP上要跑两个Vlan，所以AP接的路由器口一定要是taaged口或者是trunk口。
在改变trunk口的时候一定要保证你能够使用serial线直连AP，因为更改了路由器口的时候要在命令行内对AP 进行设置。
