无线终端无法获取到地址

组网：ac旁挂汇聚交换机，汇聚交换机下接poe，poe接无线ap

ac本地转发，现场终端无法获取到ip地址

1、查看ap的状态都是正常注册上线到ac的且版本都是适配的。

2、ac下发的map文件都是放通了管理和业务，因此map文件无问题。

3、查看ac的日志诊断，先要分清楚是无法关联wifi还是无法获取到ip地址。

很显然ac日志里面有终端连接wifi的日志信息，所以故障现象是终端连到wifi之后无法获取到地址。

4、确认故障之后，让现场在ap上起一个业务vlan，开启dhcp自动获取地址发现可以获取到ip地址，因此ac到ap直接线路质量和DHCP服务器端配置均无问题。

5、进一步检查配置发现存在如下的问题，渠道在服务模板视图和ap视图下都配置了业务vlan：

# 

wlan service-template jtpv ssid JTPV 

 client forwarding-location ap vlan 50 

 akm mode psk 

 preshared-key pass-phrase cipher $c$3$z6mWl8nuBaoAnjMDLYA0FBAKHcTlXWtvEStfXZE= cipher-suite ccmp 

 security-ie rsn 

 service-template enable 

#

wlan ap 00dd-b615-3ce0 model WA6320-D 

 serial-id 219801A2BT821AE002WM 

 map-configuration flash:/WiFi_AP.txt

 vlan 1 

 radio 1 

     radio enable 

     service-template jtpv 

 radio 2 

     radio enable 

     service-template jtpv 

 gigabitethernet 1

ap视图下的业务vlan 为vlan1，服务模板视图下的业务vlan 为vlan50.

  业务vlan存在如下的优先级：

射频口下服务模板后vlan >  AP  > AP组 > 服务模板下 。

因此导致现场实际下发的业务vlan是vlan1.

让渠道在radio口下加vlan50，将业务vlan50的优先级提高，问题解决。
