Parameter
peer: Allows time request and query on the local NTP server. The local clock can also
be synchronized to the remote server.
server: Allows time request and query on the local NTP server. The local clock cannot
be synchronized to the remote server.
synchronization: Allows only time request on the local NTP server.
query: Allows only query on the local NTP server.
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 permission to the local
NTP server.
Use the undo ntp-service access command to cancel the configured access control
permission.
By default, the access permission to the local NTP server is peer.
Configuring access control permission to the NTP server only provides a least security
measure. Performing authentication is a more reliable way to improve security.
A received access is matched in this order: peer, server, synchronization, and query.
Example
# Configure the access permission of the peer defined in ACL 2076 to be peer.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
[Quidway] ntp-service access peer 2076
# Configure the access permission of the peer defined in ACL 2028 to be server.
