Field Descri
p
tion
reference
Reference clock ID of the clock source
1. 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.
2. 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
ranges from 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
and cannot be used as a reference clock.
reach Reachability count of the clock source. 0 indicates that the clock source in 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 second by default. If the time length is greater than 2048 seconds, it is
displayed in minute; if greater than 300 minutes, in hour; if greater than 96 hours, in
day.
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 system, namely, the current reference source, with a
system clock stratum level less than or equal to 15.
• 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.
