Announce:用于主时钟的广播,使得从时钟能够选择最优的主时钟进行同步,尤其是在多主时钟环境下非常有用。 PDelay_Req 和 PDelay_Resp:用于点对点同步,尤其是在网络拓扑结构为点对点的情况下。 1-step 模式与 2-step 模式的区别: 1-Step 模式: 在1-step 模式 中,Sync报文直接携带主时钟的时间戳。同步操作只需要...

- `logMinPdelayReqInterval`:设置ptp4l发送点对点延迟请求的间隔时间。 3.运行ptp4l 一旦配置文件完成,我们可以使用以下命令启动ptp4l: sudo ptp4l -f /etc/ptp4l.conf -i <interface> 其中,`<interface>`是你配置ptp4l使用的网络接口。 4.配置ptp4l从站 如果您想在网络中运行多个PTP时钟,您需要将一...
