  • 链路调测
背景信息
图1 调测1588v2典型组网 

操作步骤
  1. 查看GrandMaster设备(即RouterA)的频率和时间信号是否与BITS设备同步。
  1. 在RouterA上执行命令display clock source,查看BITS设备的频率信号是否成功输入到RouterA。
  1. system-view[HUAWEI] sysnameRouterA [RouterA] display clock source Master clock source: Source Description Priority Sa-bit Input SSM Forcessm Sourcestate * 1 BITS0 19 sa4 unknown on normal 2 BITS1 1 sa4 unknown on abnormal 4 LPU2 19 -- unknown on normal 5 LPU3 19 -- unknown on normal 6 LPU4 19 -- unknown on normal 8 LPU6 19 -- unknown on abnormal 11 PTP 19 -- unknown on abnormal
  1. 在RouterA上执行命令display clock config,查看RouterA的频率是否锁定。
  1. [RouterA]display clock configCurrent source: 1 Workmode: manual SSM control: off Primary source: 1 Output SSM Level:bits0:unknown bits1:unknown bits2:-- bits3:-- Current source step into pull-in range Clock is in lock mode
  1. 在RouterA上执行命令display ptp all,查看1588v2模块的时间源是否跟踪到BITS。

  1. 在RouterA、RouterB和RouterC上分别执行display ptp all命令,查看RouterA、RouterB和RouterC的1588v2协议运行状态和1588v2端口的主备状态。
  • RouterA跟踪BITS输出的时钟,1588v2端口处于master状态。
  • RouterB跟踪RouterA输出的PTP时钟。RouterB与RouterA连接的1588v2端口处于slave状态,与RouterC连接的1588v2端口处于master状态。
  • RouterC跟踪RouterB输出的PTP时钟。RouterC与RouterB连接的1588v2端口处于slave状态。

 说明:
  1. RouterB,RouterC均使用1588v2方式恢复频率。

用户可以根据网络规划选择配置时钟同步协议,本节介绍了1588v2的调测方法。

已完成以下配置,设备运行正常。

如图1所示,在该网络中部署1588v2协议,RouterA、RouterB和RouterC都为BC设备。保证RouterA通过主控板上连接的时钟线缆同步BITS设备的频率和时间信号,RouterB通过部署1588v2协议同步RouterA的频率和时间信号,RouterC通过部署1588v2协议同步RouterB的频率和时间信号。

  1. 在RouterA,RouterB,RouterC上分别运行display ptp utc命令,查看UTC时间都相同。这说明三台设备的时间已经达到了秒级的同步。

  1. 在RouterB上以几秒钟为间隔连续执行display ptp all命令三到五次,观察Realtime(T2-T1)字段的显示数值能否稳定在某一个值,如果稳定,就说明RouterB的时间已经与RouterA设备同步了。

    在RouterC上重复上述操作,可以判断RouterC的时间是否与RouterB同步。

    1588 slave设备在时间同步状态下,Realtime(T2-T1)字段的稳定值根据1588v2端口所在的子卡的类型不同而不同,一般在几十到几百纳秒。

    1588 slave设备上的display ptp all命令回显中的Max(T2-T1)和Min(T2-T1)字段记录了设备记录的最大和最小时间差,运行reset ptp statistics all命令可以清零这两个字段的值。
