所以从时钟的clock-class级别不能配置太高,如果配置太高,从时钟的PTP接口不能进入slave状态,从而导致设备无法同步主时钟。 执行命令ptp clock-source { local | bits0 | bits1 } priority1 priority1,配置时钟源的优先级1的值。 执行命令ptp clock-source { local | bits0 | bits1 } priority2 priority2,...

clock-class值越小,级别越高,当级别小于128时,该设备不能作为从时钟。所以从时钟的clock-class级别不能配置太高,如果配置太高,从时钟的PTP接口不能进入slave状态,从而导致设备无法同步主时钟。 执行命令ptp clock-source{local|bits0|bits1}priority1priority1,配置时钟源的优先级1的值。
