WA6520H-HI 电信闪讯 ppoe场景下 出现端口dhcp异常，换端口故障恢复

环境:

WA6520H-HI  -》  FS5300-48US  -》   S6520X-30QC -》  中兴 -》  电信bars

终端通过无线ap有线端口接入 ，6520做qinq  内部vlan2116   外部vlan 2022  其余设备vlan透传

故障现象:

出现个别终端获取不到ip地址，通过更换ap有线端口地址恢复故障，故障试查看mac地址已经到中兴交换机侧，电信端查看mac地址回显较慢，但mac地址已经到电线侧了。故障终端在有问题的端口故障依旧，更换端口后故障立马恢复，现场同环境下终端正常
