本文使用比较简单容易理解的拓扑详细介绍了WC7520是如何跨三层注册AP，即AP跟WC7520接在不同的VLAN中的关联应用
固件版本
WC7520:V2.0.13_2015
WNDAP350:V2.0.1(为了更详细的介绍WC7520是如何跨三层发现AP并自动将AP升级成瘦AP，此文以WNDAP350胖AP固件V2.0.1为例)
GSM7352PS:V8.0.3.11
一、网络拓扑
三层交换机GSM7352PS上创建两个VLAN：
- ·VLAN10 :192.168.0.1/24，把1端口划分到VLAN10并且属于untag标记
- ·VLAN20: 192.168.1.1/24，把2端口划分到VLAN20并且属于untag标记
- ·在GSM7352PS上创建VLAN20的DHCP地址池为AP分配地址
二、配置说明
- ·WC7520的IP地址默认192.168.0.250，直接连GSM7352PS的同网段的VLAN10的第1端口
- ·WNDAP350默认IP地址192.168.0.237，由于要跨三层关联WC7520，所以要先把AP的IP地址改为自动获取，连到GSM7352PS的VLAN20的第2端口
三、注意事项
- ·由于WC7520跨三层发现AP时只能在AC上手动指定AP所在的网段，而且AP只能读取DHCP Option43 hex 0204XXXXXX信息来关联AP，XXXXXX代表AC的IP地址的16进制.
- ·三层交换机一定要支持DHCP SERVER功能，并且支持DHCP Option43 hex功能.
- ·在跨三层关联建议最好将AP的地址改为自动获取，否则跟所接VLAN网段不一致的话是无法从AC上跨三层发现AP的.

- WC7520的主要配置
登陆WC7520的管理界面192.168.0.250，默认的用户名admin，密码password
通过Access Point->Discovery->Discovery Wizard菜单关联AP，选择Factory default state，点NEXT
因为是跨三层关联，选择Different L3 network-different VLANs or behind IP subnets，点NEXT
输入AP所在网段的IP地址范围，点NEXT
WC7520根据指定的IP段把发现的AP显示在列表中
勾选上AC发现的AP，点ADD，在弹出来的密码框内输入AP的密码password
WC7520首先会先将AP升级成瘦AP：Firmware upgrade required
AP的升级过程大概需要5分钟左右，AP升级成功后就可以关联到WC7520：Connected
