终端接入无线后无法获取IP地址

AC旁挂核心，核心下联POE接入交换机，POE交换机连接AP

终端连接后无法获取IP地址

终端连接后无法获取IP地址

AP可以获取地址，终端无法获取地址，在DHCP服务器设备上debug查看

dhcp交互没有问题，但是终端还是无法获取到地址，在终端抓包查看是否收到DHCP server的offer

发现终端一直没有收到offer报文，查看AC中下发的map文件和AP下发的配置发现：

System-view

vlan 10

vlan 100

interface gigabitethernet1/0/1

port link-type trunk

port trunk permit vlan 10 100

interface gigabitethernet1/0/2

port link-type trunk

port trunk permit vlan 10 100

查看AP的诊断发现UP的接口为SGE接口，下发的map文件配置为GE接口的配置。

Wa6530的SGE接口为POE供电接口。

修改map文件，下发正确的SGE接口的配置。
