Chapter 3 NTP Configuration Commands
Use this command to configure the access control priority
of the ntp service. NTP services access control function
provides a minimal security measures (more secure way is
to use the NTP authentication mechanism).
When an access request arrives, NTP service matches the
rules in accordance with the sequence from the smallest to
the largest to access restriction, and the first matched rule
shall prevail. The matching order is peer, serve,
serve-only, query-only.
Caution:
Control query function is not supported in the current
system. Although it matches with the order in accordance
with the above rules, the related requests about the control
and query are not supported.
If you do not configure any access control rules, then all
accesses are allowed. However, once the access control
rules are configured, only the rule that allows access can
be carried out.
The following example shows how to allow the peer device
in acl1 to control the query, request for and synchronize
the time with the local device; and limit the peer device in
acl2 to request the time for the local device:
Ruijie(config)# ntp access-group peer 1
Ruijie(config)# ntp access-group serve-only 2
Command Description
ip access-list Create the IP access control list.
