Description
Use the display ntp-service trace command to display the brief information of each NTP time server
along the time synchronization chain from the local switch to the reference clock source.
Example
# View the brief information of each NTP time server along the time synchronization chain from the local
switch to the reference clock source.
<Sysname> display ntp-service trace
server 127.0.0.1,stratum 3, offset 0.018739, synch distance 0.04724
server 172.1.2.3,stratum 2, offset 0.030714, synch distance 0.01094
refid LOCL
The above information displays the time synchronization chain of server 127.0.0.1: server 172.0.0.1 is
synchronized to server 172.1.2.3, and server 172.1.2.3 is synchronized to the local clock source.
Table 1-3 display ntp-service trace command output description
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
milliseconds.
synch distance
The synchronization distance relative to the
upper-level clock, in seconds
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.
ntp-service access
Syntax
ntp-service access { peer | server | synchronization | query } acl-number
undo ntp-service access { peer | server | synchronization | query }

Parameter
query: Control query right. This level of right permits the peer device to perform control query to the
NTP service on the local device but does not permit the peer device to synchronize its clock to the local
device. The so-called “control query” refers to query of state of the NTP service, including alarm
information, authentication status, clock source information, and so on.
