Chapter 6 Provisioning
Provisioning NTP Associations
Provisioning NTP Associations
The SyncServer can have multiple associations, each with a different Role. NTP
associations with non-valid IP addresses and domain names are not shown in the
Associations list. (If a known good domain name does not appear on this list, there
may be a problem with the DNS server configuration or with the DNS service itself.)
Table 6-9 describes the method to add a new NTP association.
Table 6-10 describes the method to modify an existing NTP association.
Table 6-11 provides descriptions of NTP Association configuration parameters.
The list of Current NTP Associations always includes the local Hardware Clock,
which:

Cannot be deleted or edited.

Is configured as a preferred server
("server 127.127.45.0 prefer # pseudoaddress for the timing engine" in ntp.conf).

Is displayed at the top of the list.
The user should consider adding NTP servers available on the local network to the
list of Current NTP Associations.
Note:
The NTP hardware reference clock is automatically
marked with the NTP "prefer" setting and this can't be
unselected by the user. The system will not prevent the user
from setting multiple associations as "prefer", although this is
usually not useful.
