Field Description
source
•
When the reference clock is the local clock, the field displays
LOCAL
(
number
). It 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
displays the IP address of the NTP server. If this field displays
0.0.0.0
,
the IP address of the NTP server has not been resolved successfully.
reference
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 displays
LOCL
.
{
When the stra field has another value, this field displays the IP
address of the local clock.
•
If the reference clock is the clock of another device on the network, this
field displays the IP address of the device. If the device supports IPv6,
this field displays the MD5 digest of the first 32 bits of the IPv6 address
of the device. If this field displays
INIT
, the local device has not
established a connection with the NTP server.
stra
Stratum level of the clock source, which determines the clock accuracy. The
value is in the range of 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 and cannot be used as a reference clock.
reach
Reachability count of the clock source. 0 indicates that the clock source is
unreachable.
poll
Polling interval in seconds. It is 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 (m).
•
If the time length is greater than 300 minutes, it is displayed in hours
(h).
•
If the time length is greater than 96 hours, it is displayed in days (d).
If the time when the most recent NTP message was received or when the
local clock was updated most recently is behind the current time, this field
displays a hyphen (-).
offset
Offset of the system clock relative to the reference clock, in milliseconds.
delay
Roundtrip delay from the local device to the NTP server, in milliseconds.
disper
Maximum error of the system clock relative to the reference source, in
milliseconds.
[12345]
•
1
—Clock source selected by the system (the current reference source).
It has a system clock stratum level less than or equal to 15.
•
2
—The stratum level of the clock source is less than or equal to 15.
•
3
—The clock source has survived the clock selection algorithm.
•
4
—The clock source is a candidate clock source.
•
5
—The clock source was created by a configuration command.
Total sessions
Total number of associations.
