Server
127.0.0.1
Stratum
3, jitter
0.000, synch distance 0.0000.
Server
3000::32
Stratum
2 , jitter 790.00, synch distance 0.0000.
RefID

The output shows that server 127.0.0.1 is synchronized to server 3000::32, and server 3000::32 is
synchronized to the local clock.
Table 10
Command output
Field
Description
Server
IP address of the NTP server.
Stratum
Stratum level of the NTP server.
jitter
Root mean square (RMS) value of the clock offset relative to the upper-level clock, in
seconds.
synch distance
Synchronization distance relative to the upper-level NTP server, in seconds,
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 Local. Otherwise, it is displayed as the IP
address of the primary reference clock.
ntp-service acl
Use
ntp-service acl
to configure the access-control right for peer devices to access NTP services of the
local device.
Use
undo ntp-service acl
to remove the configured NTP service access-control right.
