Field Descri
p
tion
Reference clock ID
After the system clock is synchronized to a remote time server, this field
indicates the address of the remote time server; after the system clock is
synchronized to a local reference source, this field indicates the address
of the local clock source:
• When the local clock has a stratum level of 1, the value of this field is
“LOCL”;
• When the stratum of the local clock has another value, the value of this
field is the IP address of the local clock.
Nominal frequency The nominal frequency of the local system hardware clock, in Hz
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.
