Table 1-3 display ntp-service trace command output description
Field Description
server IP address of the NTP server
stratum
The stratum level of the corresponding system
clock
offset
The clock offset relative to the upper-level clock,
in milliseconds.
synch distance
The synchronization distance relative to the
upper-level clock, in seconds
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
Syntax
ntp-service access { peer | server | synchronization | query } acl-number
undo ntp-service access { peer | server | synchronization | query }
View
System view
Parameters
query : Control query right. This level of right permits the peer device to perform control query to the
NTP service on the local device but does not permit the peer device to synchronize its clock to the local
device. The so-called “control query” refers to query of state of the NTP service, including alarm
information, authentication status, clock source information, and so on.
synchronization : Synchronization right. This level of right permits the peer device to synchronize its
clock to the local switch but does not permit the peer device to perform control query.
server : Server right. This level of right permits the peer device to perform synchronization and control
query to the local switch but does not permit the local switch to synchronize its clock to the peer device.
peer : Peer right. This level of right permits the peer device to perform synchronization and control query
to the local switch and also permits the local switch to synchronize its clock to the peer device.
acl-number : Basic Access Control List (ACL) number, in the range of 2000 to 2999.
Description
Use the ntp-service access command to set the access control right from the remote device to the
local NTP server.
Use the undo ntp-service access command to remove the configured access control right to the local
NTP server.
By default, the access control right from the remote device to the local NTP server is peer .
