Field DescriptionField Name
Difference in clock timing, in parts per million (ppm).
NOTE: Starting in Junos OS Release 16.1R2, if the clock source is locked and the deviation exceeds
10 ppm, the status of the configured source is displayed in the command output as in-use. This status
indicates that the clock source is locked even though the clock has significant deviation.
Deviation (in ppm)
Previous difference in clock timing, if any, in ppm.Last deviation (in ppm)
Information about clock sources eligible for selection as master clock.Configured sources
Information about external clock sources.Source
Indicates priority of external clock sources:
• primary—Source is a primary reference.
• secondary—Source is a secondary reference.
Priority
Current difference in clock timing, in ppm:
• measuring—Establishing source deviation.
• number—Deviation in ppm.
Deviation (in ppm)
Previous difference in clock timing, in ppm:
• number—Deviation in ppm.
Last deviation (in ppm)
Indicates status of external sources:
• present—Source is configured and present.
• qualified—Source is eligible for synchronization source.
