Current NTP Associations
To edit or delete an association, select it using the checkbox and then click the EDIT or
DELETE button below. If the user selects EDIT, the details for that association are displayed
under Add/Edit NTP Association for the user to edit. Use the SAVE button to save the
changes and the RESTART button to make any changes take effect.
The list of Current NTP Associations always includes the Hardware Clock, which:
n Cannot be deleted or edited.
n Is configured as a preferred server ("server 127.127.45.0 prefer # pseudoaddress for the
timing engine" in ntp.conf).
n Is displayed at the top of the list.
Additionally, the factory default configuration includes three Stratum 1 NTP servers operated
by Microsemi on the Internet.
The user should consider adding NTP servers available on the local network to the list of Cur-
rent NTP Associations.
Add/Edit NTP Association
Use Add/Edit NTP Association to edit existing associations or to add new ones. The Syn-
cServer can have multiple associations, each with a different Role.
In the following explanations, the term "SyncServer" means "the local NTP daemon on the
SyncServer".
Role
n
Server:
n Addressing: Use with IPv4 class A, B and C addresses.
n Description: Creates a persistent association between the SyncServer (client)
and an NTP node (server). The client synchronizes with the server if the client's
clock selection algorithm selects this server as the best clock. Typical server asso-
ciations include: the hardware clock, the factory default NTP servers, and servers
added by the user. Also see system peer mode: client under NTP Daemon
Status (on page 28).
n Typical Usage: The user creates a Server association to designate an NTP node
that has an NTP Stratum better or equal to that of the SyncServer (client). Often,
the NTP server is another Stratum 1 server with a GPS reference that is outside
the user's administrative jurisdiction. The NTP servers operated by Microsemi
that are part of the factory default configuration are an example of this.
n
Peer:
n Addressing: Use with IPv4 class A, B and C addresses.
n Description: Creates a persistent symmetric-active association between the Syn-
cServer (peer1) with an NTP node (peer2). For the NTP node running in sym-
metric passive mode, there is nothing needs to be done on the NTP node.
However, the NTP node can be configured in symmetric active mode too. When
