巴西Light Drive OLT对接zte方案ONU互联互通调试

本文档详细介绍了在巴西Light Drive OLT上遇到的ONU无法通过PPPoE和DHCP获取外网IP的问题。通过分析OLT配置，发现ONU-Profile配置正常，但缺少gemport ID和vlan映射。调试过程中，检查了ONU的vlanID、TCONT值和GEMPORTID值，发现接收到的gemportID与OLT系统下发的不一致。针对MEClass ID=268的双向属性问题进行深入探讨，以解决互通问题。

当前问题： ONU对接OLT后，PPPoE和DHCP 接入方式都无法获取到外网IP

1、先分析 OLT配置
注意配置了一个ONU-Profile，在GPON端口下把该模版绑定到指定的ONUID上即可实现业务互通
ONU-profile配置：

hostname LightDrive
username admin privilege 15 password admin
onu-profile 1102W
     service ethernet 1
       dba enable type sr eligibility best-effort
       tcont 1 cir 512 assured 0 pir 49984
       switchport mode trunk
       switchport trunk allowed vlan add 2010
     service ip-host vlan 2011 ip address dynamic # OLT OMCI下发DHCPWAN连接
     virtual-eth 1
       associate service ethernet 1  #在虚拟端口VEIP上关联上面的service ethernet 1
    !
OLT上联口配置
interface ge0.5
 switchport
 switchport mode trunk
 switchport trunk allowed vlan add 402
 switchport trunk allowed vlan add 2010-2011
 switchport trunk allowed vlan add 2013
!    
GPON接口配置：
 interface gpon0.3
     switchport mode trunk
     switchport trunk allowed vlan all
     gpon multicast enable
     pon-link enable
     onu auto-discovered enable interval 30
     onu profile add 1102W onu-index 0-6
     onu mgmt-mode ip-path 5 tftp
     onu mgmt-mode ip-path 5 uri 10.80.42.48 file 46494F470800A634_20190401115004.xml
    !

从上面OLT配置看了没有什么大的问题，与中兴华为等OLT唯一不同的地方就是这里没有看到 gemport ID和vlan 映射相关指令；
我们分析下 OLT 这个ONU-Profile：
onu-profile 1102W #创建一个模版
service ethernet 1 #创建一个服务类型Ethernet 1
dba enable type sr eligibility best-effort #创建DBA
tcont 1 cir 512 assured 0 pir 49984 #创建tcont绑定带宽限速
switchport mode trunk #设置eth端口模式 trunk
switchport trunk allowed vlan add 2010 #添加vlan2010 到该端口下
service ip-host vlan 2011 ip address dynamic # OLT OMCI下发DHCPWAN连接
virtual-eth 1 #创建业务虚拟端口 VEIP
associate service ethernet 1 #关联上面的服务类型eth 1

上面可以看出该OLT 对gemportID的创建是基于 vlan来创建；有几个vlanID 就会分配多少个gemportID
2.、调试 ONU
进入ONU命令行：
查看OLT下发下来的vlanID
