What is Precision Time Protocol?
Precision Time Protocol (PTP) is a cloudSwXtch feature that facilitates clock synchronization between agents connected to the network. The cloudSwXtch acts as the Master Node, passing on the information gained from the true clock source to the Follower Nodes or agent end points.
Information regarding PTP will display in both swXtch-top under the PTP page and wXcked Eye under Timing Nodes. Both cloudSwXtch tools will show the local and root offset. The local offset denotes the offset in time from the cloudSwXtch to the xNIC. The root offset denotes the offset in time from the True Clock Source and the cloudSwXtch's follower nodes (xNICs). The root value will always be larger than the local since the distance between the follower node and the True Clock Source is greater than the offset between a cloudSwXtch and xNIC.
