Table 208: show ptp clock Output Fields (continued)
Field DescriptionField Name
Represents an estimate of the variations of the local clock when it is not synchronized via PTP to
another clock.
Log Variance
Priority value of the clock. Lower value takes precedence.Clock Priority1
Prioritize the masters to avoid confusion when the Clock Priority1 value is the same for different masters
in a network.
Clock Priority2
Offset between International Atomic Time (TAI ) and Coordinated Universal Time (UTC) times. The
value is 34 seconds as of January 2012.
UTC Offset
When TRUE, the last minute of the current UTC day has only 59 seconds (instead of the 60 SI seconds).Leap59
When TRUE, the last minute of the current UTC day has 61 seconds (instead of the 60 SI seconds).Leap61
When TRUE, the timescale and the UTC offset are traceable to a primary reference.Time Traceable
When TRUE, frequency determining the timescale is traceable to a primary reference.Frequency Traceable
Time source external to the Precision Time Protocol (PTP), which provides time and/or frequency as
appropriate. The time source is traceable to the international standards laboratories maintaining
clocks that form the basis for the International Atomic Time (TAI) and Universal Coordinated Time
(UTC) timescales. Examples of these are Global Positioning System (GPS), NTP, and National Institute
of Standards and Technology (NIST) timeservers.
Time Source
Interval in seconds between the delay-request messages sent by the slave to the master.Delay Req Sending Time
Number of boundary clocks between the local clock and the foreign master clock.Steps Removed
Set to TRUE, when the system is used in ordinary slave clock mode; otherwise, FALSE.Slave-only
EUI-64 clock identifier of the immediate upstream master clock.Parent Id
EUI-64 clock identifier of the grandmaster clock.GMC Id
Denotes the grandmaster clock’s traceability of the distributed time or frequency.GMC Class
Indicates the expected accuracy of the grandmaster clock.GMC Accuracy
Represents an estimate of the variations of the grandmaster clock.GMC Variance
Priority1-value of the grandmaster clock.GMC Priority1
Priority2-value of the grandmaster clock.GMC Priority2
