Table 1-1 display ntp-service sessions command output description
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:
z When the value of the stra field is 0 or 1, this field will be
“LOCL”;
z When 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, which determines the clock
precision. The value range is 1 to 16. The clock precision
decreases from stratum 1 to stratum 16. A stratum 1 clock
has the highest precision, and a stratum 16 clock is not
synchronized.
reach
Reachability count of the clock source. 0 indicates that the
clock source in unreachable.
poll
Poll interval in seconds, namely, the maximum interval
between successive NTP messages.
now
The length of time 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 switch, namely, the current
reference source.
2: Stratum level of the clock source is less than or equal to
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.
