Description
Use the display ntp-service trace command view the brief information of each NTP server along the
NTP server chain from the local device back to the primary reference source.
The display ntp-service trace command takes effect only if routes are available between the local
device and all the devices on the NTP server chain; otherwise, this command will fail to display all the
NTP servers on the NTP chain due to timeout.
Examples
# View the brief information of each NTP server from the local device back to the primary reference
source.
<Sysname> display ntp-service trace
server 127.0.0.1,stratum 2, offset -0.013500, synch distance 0.03154
server 133.1.1.1,stratum 1, offset -0.506500, synch distance 0.03429
refid LOCL
The information above shows an NTP server chain for the server 127.0.0.1: The server 127.0.0.1 is
synchronized to the server 133.1.1.1, and the server 133.1.1.1 is synchronized to the local clock
source.

Field Description
server IP address of the NTP server
stratum The stratum level of the corresponding system clock
offset The clock offset relative to the upper-level clock, in seconds
synch distance
The synchronization distance relative to the upper-level
clock, in seconds, and calculated from dispersion and
roundtrip delay values.
refid
Identifier of the primary reference source. When the stratum
level of the primary reference clock is 0, it is displayed as
LOCL; otherwise, it is displayed as the IP address of the
primary reference clock.
