4.4 display ntp-service trace

Syntax

display ntp-service trace [ X.X.X.X ]

View

All views

Parameter

X.X.X.X: IP address of the NTP server operating as the reference clock source.

Description

Using the display ntp-service trace command, you can display the brief information of the NTP time servers passed for tracing back to the reference clock source from the local device.

This command enables you to set out from the local device, trace along the time synchronization NTP server link back to the reference clock source, and display the brief information of all the NTP servers along the link.

Example

Display the brief information of the NTP time servers passed by when tracing from the local device to the reference clock source.

[3Com] display ntp-service	trace
server4: stratum 4, offset	0.0019529, synch distance 0.144135
server3: stratum 3, offset	0.0124263, synch distance 0.115784
server2: stratum 2, offset	0.0019298, synch distance 0.011993
server1: stratum 1, offset	0.0019298, synch distance 0.011993 refid 'GPS
Reciever'

The information shows the synchronization link of server4, along which, server4 synchronizes with server3, server3 with server2, server2 with server1, and server1 with the clock source GRP Reciever.
