Description
•
When the reference clock is the local clock, the field is displayed as
LOCAL(number), which indicates that the IP address of the local clock is
127.127.1.number, where number represents the NTP process number in the
range of 0 to 3.
•
When the reference clock is the clock of another device, the field is
displayed as the IP address of the NTP server.
Reference clock ID of the NTP server.
•
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 is displayed as
"LOCL."
When the stra field has another value, this field is displayed as the IP
address of the local clock.
•
If the reference clock is the clock of another device on the network, this field
is displayed as the IP address of the device.
Stratum level of the clock source, which determines the clock accuracy. The
value ranges from 1 to 16. The clock accuracy decreases from stratum 1 to
stratum 16. A stratum 1 clock has the highest precision, and a stratum 16 clock
is not synchronized.
Reachability count of the clock source. 0 indicates that the clock source in
unreachable.
Polling interval in seconds. It is the maximum interval between successive NTP
messages.
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 of the system clock relative to the reference clock, in milliseconds
Roundtrip delay from the local device to the NTP server, in milliseconds
Maximum error of the system clock relative to the reference source, in
milliseconds.
•
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.
