确认ONU在线状态
display onu interface OltX/X/X # 检查ONU的"State"字段是否为"Up"
若状态为"Offline"：
- 检查光纤连接、光功率（标准值：-3~-24dBm）
- 确认ONU型号兼容性（如ET814-E需绑定标签MAC+1，ET924-H需绑定ONU芯片MAC）
- 排查ONU黑名单：display ftth blacklist
检查管理VLAN配置
- OLT虚接口与管理VLAN一致性：
  interface Vlan-interfaceX # 需与ONU管理VLAN相同 ip address 192.168.1.1 255.255.255.0
- ONU侧启用管理接口：
  interface OnuX/X/X:X management-vlan Y # 与OLT虚接口VLAN一致 undo shutdown management-vlan-interface # 关键！默认接口为关闭状态
验证IP地址获取方式
- 静态配置：
  ip address 192.168.1.2 255.255.255.0 gateway 192.168.1.1
- DHCP获取：
  ip address dhcp-alloc
注意：新配置会覆盖旧地址，修改后建议重启ONU（reboot onu）
检查路由与端口隔离
- 确认OLT与ONU在同一网段，或配置静态路由
- 关闭UNI口隔离功能（若开启）：
  uni Z port-isolation enable # 检查是否开启，必要时undo关闭
版本兼容性处理
- ONU重启后地址丢失：删除管理口配置重新下发（版本R758X已知问题）
- ONU型号显示异常/流量统计失败：升级ONU固件至支持CTC3.0规范版本
进阶诊断
- 开启OLT端口调试：
  debugging epon packet onu X/X/X:X
- 检查DBA带宽限制：
  display onu service-sla X/X/X:X
