Table 15 Command output
source
• When the reference clock is the local clock, the field displays LOCAL
(number). It indicates that the IP address of the
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:
ï‚¡ When the value of the stra field is 0 or 1, this field displays LOCL.
ï‚¡ 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 sec
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 length is greater than 999 days, it is displayed in years (y).
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.
