Output: ptp4l[2669. Skip to content. It is particularly useful for monitoring. It uses unicast messages, but unlike PTP in the unicast mode it does not require the server to keep any state specific to the client. unicast_listen When enabled, this option allows Hello all, i am trying to sync an embedded platform with my server as using my server as master and the embedded platform as slave using G. The port that claims a given table does so by including the ID as the value of its For large data center deployments, unicast is preferred over multicast because it significantly simplifies network design and software requirements.
