Configuring Access-Control Rights
With the following command, you can configure the NTP service access-control right to the local switch.
There are four access-control rights, as follows:
z query : control query permitted. This level of right permits the peer switch to perform control query
to the NTP service on the local switch but does not permit the peer switch to synchronize its clock
to the local switch. The so-called “control query” refers to query of some states of the NTP service,
including alarm information, authentication status, clock source information, and so on.
z synchronization : server access only. This level of right permits the peer switch to synchronize its
clock to the local switch but does not permit the peer switch to perform control query.
z server : server access and query permitted. This level of right permits the peer switch to perform
synchronization and control query to the local switch but does not permit the local switch to
synchronize its clock to the peer switch.
z peer : full access. This level of right permits the peer switch to perform synchronization and control
query to the local switch and also permits the local switch to synchronize its clock to the peer
switch.
From the highest NTP service access-control right to the lowest one are peer, server,
synchronization , and query. When a switch receives an NTP request, it will perform an access-control
right match and will use the first matched right.
Configuration Prerequisites
Prior to configuring the NTP service access-control right to the local switch, you need to create and
configure an ACL associated with the access-control right. For the configuration of ACL, refer to the
ACL in H3C WX6103 Access Controller Switch Interface Board Configuration Guide.
