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。
