摘　　要：OAM/OMCI作为PON系统中的远程管理协议,对整个PON系统能否正常工作起着至关重要的作用。无论是对于开发中的还是已经部署的现场ONU设备,都能够比较方便地获取到OAM/OMCI交互数据,对于功能调试、对接测试和故障排除都具有重要的意义。提出了一种在ONU驱动层软件上利用报文镜像获取OAM/OMCI报文的调试方法,制定了报文封装格式并开发了对应的插件。最后,在实际环境中验证了该方法,证明了其有效性。As a remote management protocol in a PON system,OAM/OMCI plays a crucial role in the normal operation of the entire PON system.OAM/OMCI interaction data can be easily obtained for both developed or deployed onsite ONU devices,which is very meaningful for functional debugging,connection testing and troubleshooting.A debugging method for obtaining OAM/OMCI messages by using message mirroring on the ONU driver layer software is propossed,the message encapsulation format is formulated and the corresponding plugins is developed.Finally,the method is validated in a real environment,and its effectiveness is proved.
