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。

1. RouterB，RouterC的时间都与各自的Master设备同步。

1. [RouterA]display ptp utcUTC Time:2012-01-01 14:53:26[RouterB]display ptp utcUTC Time:2012-01-01 14:53:26[RouterC]display ptp utcUTC Time:2012-01-01 14:53:26

 说明：

1. RouterB，RouterC均使用1588v2方式恢复频率。
