Field Descri
p
tion
reference
Reference clock ID of the clock source:
• If the reference clock is the local clock, the value of this field is related to the
value of the stra field:
{ When the value of the stra field is 0 or 1, this field will be LOCL.
{ When the stra field has another value, this field will be the IP address of
the local clock.
• If the reference clock is the clock of another device on the network, the value
of this field will be the IP address of that device.
stra
Stratum level of the clock source, which determines the clock precision. The
value is in the range of 1 to 16. The clock precision decreases from stratum 1
to stratum 16. A stratum 1 clock has the highest precision, and a stratum 16
clock is not synchronized.
reach
Reachability count of the clock source. 0 indicates that the clock source is
unreachable.
poll
Poll interval in seconds, namely, the maximum interval between successive
NTP messages.
now
Length of time from when the last NTP message was received or when the local
clock was last updated to the current time.
Time is in seconds by default. If the time length is greater than 2048 seconds,
it is displayed in minutes. If greater than 300 minutes, in hours. If greater than
96 hours, in days.
offset Offset of the system clock relative to the reference clock, in milliseconds.
delay Roundtrip delay from the local device to the clock source, in milliseconds.
disper Maximum error of the system clock relative to the reference source.
[12345]
• 1—Clock source selected by the device, namely, the current reference
source that the device is synchronizing to.
• 2—Stratum level of the clock source is less than or equal to 15.
• 3—This clock source has survived the clock selection algorithm.
• 4—This clock source is a candidate clock source.
• 5—This clock source was created by a configuration command.
Total associations Total number of associations.
