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.
Field Name |
Field Description |
---|---|
|
Number of the FPC or MIC slot. |
|
Whether the clock provides time information which is
a combination of an event message and a subsequent general message: |
|
Clock identity of the client or client as defined in IEEE 1588. |
|
Total number of PTP ports on the router. |
|
Attribute of an ordinary or boundary clock that denotes the traceability of the time or frequency distributed by the reference clock. |
|
Indicates the expected accuracy of a clock when it is the reference clock, or in the event it becomes the reference. |
|
Represents an estimate of the variations of the local clock when it is not synchronized via PTP to another clock. |
|
Priority value of the clock. Lower value takes precedence. |
|
Prioritize the primaries to avoid confusion when the |
|
Offset between International Atomic Time (TAI ) and Coordinated Universal Time (UTC) times. The value is 34 seconds as of January 2012. |

|
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. |
|
Interval in seconds between the delay-request messages sent by the client to the primary. |
|
Number of boundary clocks between the local clock and the foreign primary clock. |
|
Set to |
|
EUI-64 clock identifier of the immediate upstream primary clock. |
|
EUI-64 clock identifier of the reference clock. |
|
Denotes the reference clock’s traceability of the distributed time or frequency. |
|
Indicates the expected accuracy of the reference clock. |
|
Represents an estimate of the variations of the reference clock. |
