Field Description
Reference clock ID
Address of the remote server or ID of the
reference clock after the local clock is
synchronized to a remote NTP server or a
reference clock
Nominal frequency
Nominal frequency of the local hardware clock,
in Hz.
Actual frequency
Actual frequency of the local hardware clock, in
Hz.
Clock precision Precision of the local hardware clock
Clock offset
Offset of the local clock relative to the reference
clock, in milliseconds.
Root delay
Roundtrip delay between the local clock and the
primary reference clock source, in milliseconds.
Root dispersion
Maximum dispersion of the local clock relative to
the primary reference clock, in milliseconds.
Peer dispersion
Maximum dispersion of the remote NTP server,
in milliseconds.
Reference time Reference timestamp
display ntp-service trace
Syntax
display ntp-service trace
View
Any view
Parameters
None
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.
Examples
# 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.
