Field Description
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 Clock stratum field:
{ When the value of the Clock stratum field is 0 or 1, this field
displays LOCL.
{ When the Clock stratum field has another value, this field displays
the MD5 digest value of the first 32 bits of the IPv6 address. The
MD5 digest value is in dotted decimal format.
• If the reference clock is the clock of another device on the network, this
field displays the MD5 digest value of the first 32 bits of the IPv6
address. The MD5 digest value is in dotted decimal format. If this field
displays INIT, the local device has not established a connection with
the NTP server.
Clock stratum
Stratum level of the NTP server, which determines the clock accuracy. The
value is in the range of 1 to 16. A lower stratum level represents higher clock
accuracy. A stratum 16 clock is not synchronized and cannot be used as a
reference clock.
Reachabilities
Reachability count of the NTP server. 0 indicates that the NTP server is
unreachable.
Poll interval
Polling interval in seconds. It is the maximum interval between successive
NTP messages.
Last receive time
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 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.
Roundtrip delay Roundtrip delay from the local device to the clock source, in milliseconds.
Dispersion Maximum error of the system clock relative to the reference source.
Total sessions Total number of associations.
