Output Fields

The Output Fields lists the output fields for the show ptp all-master-clock command. Output fields are listed in the approximate order in which they appear.

Table 1: show ptp all master clock Output Fields
Field Name Field Description
Slot

Number of the FPC or MIC slot. If underlying interface is not available momentarily or is unavailable for a virtual interface, the slot number is 255.

Parent Id

EUI-64 clock identifier of the immediate upstream primary clock.

GMC Id

EUI-64 clock identifier of the reference clock.

GMC Class

Denotes the reference clock’s traceability of the distributed time or frequency.

GMC Accuracy

Indicates the expected accuracy of the reference clock.

GMC Variance

Represents an estimate of the variations of the reference clock.

GMC Priority 1

Priority1-value of the reference clock.

GMC Priority 2

Priority2-value of the reference clock.

UTC Offset

Offset between International Atomic Time (TAI ) and Coordinated Universal Time

(UTC) times. The value is 34 seconds as of January 2012.

Leap-59

When TRUE, the last minute of the current UTC day has only 59 seconds (instead of the 60 SI seconds).

Leap-61

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 primary reference.

Freq Traceable

When TRUE, frequency determining the timescale is traceable to a primary reference.

Time Scale

The PTP primary clock's best estimate of the international standard time scales.

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.

Unicast

Configure upstream unicast PTP primary clock sources.

UTC Valid

TRUE if the UTC offset is known to be correct.

Two Step

Whether the clock provides time information, which is a combination of an event message and a subsequent general message: True or False.

Alternate Master

Allows alternate masters that are not the current best master to exchange PTP timing information with client ports.

Steps Removed

Number of boundary clocks between the local clock and the foreign primary clock.

Parent SourcePort Id

Source port Id of a master clock.

ANN msg Interval

Determines the mean time interval between successive announce messages. For example, announce Interval = 2 ^ Log Interval.

Interface

Interface on which announce message is received.

PTP Stream ID

Unique Local identifier index of PTP stream created.

Sample Output

show ptp all-master-clock
