Command Manual – NTP
H3C S7500E Series Ethernet Switches Chapter 1 NTP Configuration Commands
1-5
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.
Examples
# View the brief information of each NTP server from the local device back to the
primary reference source.
