display ntp-service trace
Syntax display ntp-service trace
View Any view
Parameter 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 is available only if the local device can
ping through 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.
Example # 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.
Table 606 Description on the fields of the display ntp-service status command
Field Description
Clock status Status of the system clock
Clock stratum Stratum level of the local clock
Reference clock ID After the system clock is synchronized to a remote time server or a
local reference source, this field indicates the address of the remote
time server or the identifier of the local clock source:
■ When the local clock has a stratum level of 1, the value of this
field is “LOCL”;
■ When the local clock has another value, the value of this filed is
the IP address of the local clock).
Nominal frequency The nominal frequency of the local system hardware clock
Actual frequency The actual frequency of the local system hardware clock
Clock precision The precision of the system clock
Clock offset The offset of the system clock relative to the reference source
Root delay The roundtrip delay from the local device to the primary reference
source
Root dispersion The maximum error of the system clock relative to the primary
reference source.
Peer dispersion The maximum error of the system clock relative to the reference
source
Reference time Reference timestamp
