Procedure
l Run the display ntp-service status command to view the status of the NTP service.
l Run the display ntp-service sessions [ verbose ] command to view the status of NTP
sessions.
l Run the display ntp-service trace command to view the summary information on each
passing NTP server when tracing from the local device to the reference clock source.
----End

4.4 Configuring NTP Security Mechanisms
This section describes how to configure NTP security mechanisms to guarantee reliable clock
synchronization on networks demanding high security.
4.4.1 Establishing the Configuration Task
Before configuring NTP security mechanisms , familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This can help
you complete the configuration task quickly and accurately.
