Table 1-1 Description on the fields of the display ntp-service sessions command
Field Description
source IP address of the clock source
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:
zWhen the value of the stra field is 0 or 1, this field will be
“LOCL”;
zWhen the stra field has another value, this filed 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
reach Reachability count of the clock source. 0 indicates that the clock
source in unreachable
poll Poll interval, namely the maximum interval between successive
NTP messages.
now
The length of time in minutes from when the last NTP message was
received or when the local clock was last updated to the current time
The 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 The offset of the system clock relative to the reference clock, in
milliseconds
delay the roundtrip delay from the local device to the clock source, in
milliseconds
disper The 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 of ≤15
2: Stratum level of this system source is ≤15
3: This clock source has passed the clock selection process
4: This clock source is a candidate clock source
5: This clock source was created by a configuration command
