Output Fields

Table 1 lists the output fields for the show ptp clock command. Output fields are listed in the approximate order in which they appear.

Table 1: show ptp clock Output Fields
Field Name	Field Description
`Slot Number`	Number of the FPC or MIC slot.
`Two-step Clock`	Whether the clock provides time information which is a combination of an event message and a subsequent general message: `True` or `False`.
`Clock Identity`	Clock identity of the timeReceiver or timeReceiver as defined in IEEE 1588.
`Total Ports on Device`	Total number of PTP ports on the router.
`Clock Class`	Attribute of an ordinary or boundary clock that denotes the traceability of the time or frequency distributed by the grandmaster clock.
`Clock Accuracy`	Indicates the expected accuracy of a clock when it is the grandmaster clock, or in the event it becomes the grandmaster.
`Log Variance`	Represents an estimate of the variations of the local clock when it is not synchronized via PTP to another clock.
`Clock Priority1`	Priority value of the clock. Lower value takes precedence.
`Clock Priority2`	Prioritize the primaries to avoid confusion when the `Clock Priority1` value is the same for different primaries in a network.
`UTC Offset`	Offset between International Atomic Time (TAI ) and Coordinated Universal Time (UTC) times. The value is 34 seconds as of January 2012.
`Leap59`	When `TRUE`, the last minute of the current UTC day has only 59 seconds (instead of the 60 SI seconds).
`Leap61`	When `TRUE`, the last minute of the current UTC day has 61 seconds (instead of the 60 SI seconds).
`Time Traceable`	When `TRUE`, the timescale and the UTC offset are traceable to a timeTransmitter reference.
`Frequency Traceable`	When `TRUE`, frequency determining the timescale is traceable to a timeTransmitter reference.
`Time Source`	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.
`Delay Req Sending Time`	Interval in seconds between the delay-request messages sent by the timeReceiver to the timeTransmitter.
`Steps Removed`	Number of boundary clocks between the local clock and the foreign timeTransmitter clock.
`Slave-only`	Set to `TRUE`, when the system is used in ordinary timeReceiver clock mode; otherwise, `FALSE`.
`Parent Id`	EUI-64 clock identifier of the immediate upstream timeTransmitter clock.
`GMC Id`	EUI-64 clock identifier of the grandmaster clock.
`GMC Class`	Denotes the grandmaster clock’s traceability of the distributed time or frequency.
`GMC Accuracy`	Indicates the expected accuracy of the grandmaster clock.
`GMC Variance`	Represents an estimate of the variations of the grandmaster clock.
`GMC Priority1`	`Priority1-value` of the grandmaster clock.
`GMC Priority2`	`Priority2-value` of the grandmaster clock.
