Field Description
Actual frequency The actual frequency of the local system hardware clock, in Hz
Clock precision The precision of the system clock
Clock offset
The offset of the system clock relative to the reference source, in
milliseconds
Root delay
The roundtrip delay from the local device to the primary reference
source, in milliseconds
Root dispersion
The maximum error of the system clock relative to the primary
reference source, in milliseconds
Peer dispersion
The maximum error of the system clock relative to the reference
source, in milliseconds
Reference time Reference timestamp
display ntp-service trace
Syntax
display ntp-service trace
View
Any view
Default Level
1: Monitor level
Parameters
None
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.
