Usage guidelines
The display ntp-service trace command takes effect only when the local device and all the devices on the
NTP server chain can reach one another. Otherwise, this command is unable to display all the NTP
servers on the NTP chain due to timeout.
Examples
# Display brief information about each NTP server from the local device back to the primary reference
source.
<Sysname> display ntp-service trace
server 127.0.0.1,stratum 2, offset -0.013500, synch distance 0.03154
server 133.1.1.1,stratum 1, offset -0.506500, synch distance 0.03429
refid LOCL
The output shows an NTP server chain for server 127.0.0.1: Server 127.0.0.1 is synchronized to server
133.1.1.1, and server 133.1.1.1 is synchronized to the local clock source.
Table 14 Command output
Field Description
server IP address of the NTP server.
stratum Stratum level of the corresponding system clock.
offset Clock offset relative to the upper-level clock, in seconds.
synch distance
Synchronization distance relative to the upper-level clock, in seconds, and
calculated from dispersion and roundtrip delay values.
refid
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.
ntp-service access
Use
ntp-service access
to configure the access-control right for the peer devices to access the NTP
services of the local device.
Use
undo ntp-service access to remove the configured NTP service access-control right to the local
device.
Syntax
ntp-service access { peer | query | server | synchronization } acl-number
undo ntp-service access { peer | query | server | synchronization }
