Cisco Ptp Clock Running State

1.3.6.1.4.1.9.9.760.1.2.4.1.4

This object specifies the Clock state returned by PTP engine which was described earlier. Freerun state. Applies to a slave device that is not locked to a master. This is the initial state a slave starts out with when it is not getting any PTP packets from the master or because of some other input error (erroneous packets, etc). Holdover state. In this state the slave device is locked to a master but communication with the master is lost or the timestamps in the ptp packets are incorrect. But since the slave was locked to the master, it can run with the same accuracy for sometime. The slave can continue to operate in this state for some time. If communication with the master is not restored for a while, the device is moved to the FREERUN state. Acquiring state. The slave device is receiving packets from a master and is trying to acquire a lock. Freq_locked state. Slave device is locked to the Master with respect to frequency, but not phase aligned Phase_aligned state. Locked to the master with respect to frequency and phase.
