ptpClockRunningState
Module: AT-PTP-MIB
OID (symbolic): AT-PTP-MIB::ptpClockRunningState
OID (numeric): 1.3.6.1.4.1.207.8.4.4.4.504.1.2.4.1.4
Node type: OBJECT-TYPE
Type: PtpClockStateType
Access: read-only
Description: This object specifies the Clock state returned by a 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 has been lost or the timestamps in the PTP packets are incorrect. Since the slave was previously locked to the master, it can run in this state, with similar accuracy for some time. If communication with the master is not restored for an extended period (dependent on the clock implementation), the device should move 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.
What is ptpClockRunningState?
This read-only enumeration describes the current operational state of the PTP clock engine. States include freerun, holdover, locked, and several others. Value 'locked' means synchronized to master.
