关于一个华为EPON设备的端口命令

如果一个接在EPON设备上的用户出现掉线，此用户是LAN+PON的用户，用户直接从ONU设备端口接入用户电脑，使用5类缆。可以用如下命令进行分析。以下使用的是当地的华为5620设备。通过以下命令，可以初步判断用户的连接情况，以便进一步分析用户上网掉线的原因，另外还要结合亚信认证系统，查看用户上网记录，检查掉线的原因，最后归纳总结。这是我个人的一些处理问题的思路，请大家参考。

1. 登录设备，查看用户是否在线

M-GB_JBJ33H2DPL5620-1#display board 0/1

  ---------------------------------------               
  Board Name          : H821EPFB                   
  Board Status        : Normal                      
  ---------------------------------------

  ------------------------------------------------------------------------------
  Port  Port  Optic    MDI     Speed      Duplex    Flow-  Active   Link  
        Type  Status           (Mbps)               Ctrl   State          
  ------------------------------------------------------------------------------
     1  FE    -        auto    auto_100   auto_full off    active   online
     2  FE    -        auto    auto_100   auto_full off    active   online
     3  FE    -        auto    auto       auto      off    active   offline
     4  FE    -        auto    auto       auto      off    active   offline
      ------------------------------------------------------------------------------

2.使用命令进入单板

M-GB_JBJ33H2DPL5620-1#config

M-GB_JBJ33H2DPL5620-1(config)#interface eth 0/1

3.查询以太网端口的当前流量，此处显示 1 端口数据流量。

M-GB_JBJ33H2DPL5620-1(config-if-eth-0/1)#display port traffic 1
  The received traffic of this port(packets/s)                    =339~~~~~收到的包
  The received traffic of this port(octets/s)                     =376731
  The transmitted traffic of this port(packets/s)                 =180~~~~~发送的包
  The transmitted traffic of this port(octets/s)                  =18164

查询以太网端口参数设置及状态。当需要查询以太网端口的激活状态、链路状态、工作速率、双工模式等基本信息时，使用此命令。

M-GB_JBJ33H2DPL5620-1(config-if-eth-0/1)#display port state 1
  The port is active 
  Ethernet port is online  ~~~~~~~~~~在线
  Ethernet port is auto-negotiation to full duplex ~~~~~~~全双工
  Ethernet port rate is auto-negotiation to 100M ~~~~~~~100M
  Ethernet port does not support flow control 
  Ethernet port does not support jumbo frame
  Line-adaptive function of the ethernet port is auto-negotiation~~~~~~自动协商
  Note: For a 1000 M, electrical port in the full-duplex mode, setting MDI to 
        any value is invalid

查询以太网端口的统计信息。当需要根据以太网端口的统计信息判断设备运行是否正常时，使用此命令。
