Description

Use the display ntp-service trace command to display the brief information of each NTP time server along the time synchronization chain from the local device to the reference clock source.

Example

View the brief information of each NTP time server along the time synchronization chain from the local device to the reference clock source.

<SW4500> 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 above information displays the time synchronization chain of server4: serve4 is synchronized to server3, server3 to server2, server2 to server1, and server1 to the reference clock source GPS receiver.
