show network-clock ptp

show network-clock ptp


Show the PTP clock recovery state information. The clock recovery using PTP event messages undergoes the following servo state changes:

  • Warmup - The local reference clock is in warmup state.

  • Fast Loop - The local reference clock is being corrected and the correction is converging.

  • Bridge - The local reference clock correction has been interrupted due to changes in the clocking information in the received PTP event messages or loss of PTP event messages.

  • Holdover - Prolonged loss of PTP event messages puts the local reference clock correction to holdover state.

  • Normal - The local reference clock correction has converged and the corrected clock is synchronous to the master clock information received in the PTP event messages.
