sync

syncFreqClockQLChange

Table 1. syncFreqClockQLChange properties
Property name	Value
Application name	sync
Event name	syncFreqClockQLChange
Default severity	notice
Message format string	The system frequency clock's Quality Level (ql) has transitioned to freq_clock_ql
Cause	This notification is generated when a frequency clock transitions to a new ql.
Effect	The system's frequency clock is synced to remote clock with this ql.

syncFreqClockRefChange

Table 2. syncFreqClockRefChange properties
Property name	Value
Application name	sync
Event name	syncFreqClockRefChange
Default severity	notice
Message format string	The system frequency clock reference has transitioned to frequency reference instance instance_number
Cause	This notification is generated when a frequency reference instance selected has changed.
Effect	The system frequency clock will follow the new reference.

syncFreqClockStateChange

Table 3. syncFreqClockStateChange properties
Property name	Value
Application name	sync
Event name	syncFreqClockStateChange
Default severity	notice
Message format string	The system frequency clock state has transitioned to freq_clock_state
Cause	This notification is generated when a frequency clock transitions to a new state.
Effect	The system's frequency clock behavior is based on this state.

syncFreqInstanceAlarmChange

Table 4. syncFreqInstanceAlarmChange properties
Property name	Value
Application name	sync
Event name	syncFreqInstanceAlarmChange
Default severity	notice
Message format string	Frequency reference instance instance_number: The alarm state has transitioned to alarm_state
Cause	This notification is generated when a frequency Reference instance transitions to a new alarm state.
Effect	If there is an alarm for a frequency reference instance, it will not be qualified for use.

syncFreqInstanceQLChange

Table 5. syncFreqInstanceQLChange properties
Property name	Value
Application name	sync
Event name	syncFreqInstanceQLChange
Default severity	notice
Message format string	Frequency reference instance instance_number: The Quality Level (ql) has transitioned to ql_number
Cause	This notification is generated when a frequency reference Instance transitions to a new QL.
Effect	The new QL will be taken into account when for system frequency clock reference selection if ql-selection is set.

syncPTPParentChange

Table 6. syncPTPParentChange properties
Property name	Value
Application name	sync
Event name	syncPTPParentChange
Default severity	notice
Message format string	PTP has transitioned to new parent parent_clock_mac_address on port parent_clock_port with clockClass of parent_clockclass.
Cause	This notification is generated when the PTP clock transitions to a new parent.
Effect	The ptp clock will follow this new parent clock.

syncPTPParentChangeIP

Table 7. syncPTPParentChangeIP properties
Property name	Value
Application name	sync
Event name	syncPTPParentChangeIP
Default severity	notice
Message format string	PTP has transitioned to new parent parent_clock_ip in routing instance parent_clock_router with clockClass of parent_clockclass.
Cause	This notification is generated when the PTP clock transitions to a new IP parent.
Effect	The ptp clock will follow this new parent clock.

syncPTPPortPTSFUnusable

Table 8. syncPTPPortPTSFUnusable properties
Property name	Value
Application name	sync
Event name	syncPTPPortPTSFUnusable
Default severity	warning
Message format string	PTP detected excessive noise between PTP port number ptp_neighbor_port_number and parent clock ID ptp_neighbor_clock_id.
Cause	The PTP process detected excessive noise between the local port and the indicated external Master port.
Effect	Any Announce messages received from the indicated neighbor shall be excluded from the BMCA algorithm until this condition is cleared.

syncPTPTimeRecoveryState

Table 9. syncPTPTimeRecoveryState properties
Property name	Value
Application name	sync
Event name	syncPTPTimeRecoveryState
Default severity	notice
Message format string	PTP has transitioned to time recovery state of ptp_time_rec_state
Cause	This notification is generated when the PTP clock transitions to a new time recovery state.
Effect	The ptp clock's tim recovery behavior will be based on this state.
