Display Ntp-Service Trace - HPE FlexNetwork 5130 HI Series Network Management And Monitoring Command Reference

display ntp-service trace

Use display ntp-service trace to display brief information about each NTP server from the local
device back to the primary reference source.

Parameters
source interface-type interface-number: Specifies the source interface for sending NTP packets to
trace each NTP server from the local device back to the primary reference source. The source IP
address of the NTP packets is the IPv4 address/IPv6 address of the specified source interface. If the
IP address of an NTP server is a link-local address, the link-local address of the outgoing interface of
NTP packets is used as the source IP address of the NTP packets. If you do not specify this option,
the interface that sends the tracing NTP packets acts as the source interface.
Usage guidelines
To trace back to the primary reference source from the source interface, make sure the source
interface and the NTP servers from the local device to the primacy reference source are reachable to
each other.

Description
IP address of the NTP server.
Stratum level of the NTP server.
Root mean square (RMS) value of the clock offset relative to the upper-level
clock, in seconds.
Synchronization distance relative to the upper-level NTP server, in seconds,
calculated from dispersion and roundtrip delay values.
Identifier of the primary reference source. When the stratum level of the primary
reference clock is 0, it is displayed as LOCL. Otherwise, it is displayed as the IP
address of the primary reference clock.
