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

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.
