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.

System view 

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. 

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.
