Enter the required information into the fields:
Host: The IPaddress for the server to be used as host.
Min Poll Interval: Select a value from the drop down (the default is 3 (8s).
Max Poll Interval: Select a value from the drop down (the default is 3 (8s).
For both NTP Peers, and NTP Servers the Minimum and Maximum Poll rate for
NTP packets can be configured. Both NTP Peers and NTP Servers support either
manually configured Symmetric Key-ID/Key string pairs or the use of Auto-Key.
However, these choices are mutually exclusive and must be identically con-
figured on both the SecureSync and the NTP Peer or NTP Server. If the Sym-
metric Key-ID/Key string pair method is selected the Key-ID must be first defined
on the Symmetric Key page.
Enable Symmetric Key: Click the checkbox to enable/disable Symmetric Key. See
also: "Configuring NTP Symmetric Keys" on page117.
Note: Before you can edit the Key field, you must set up Symmetric
Keys through the Actions Panel. See "NTP: Symmetric Keys (MD5) "
on page117. Conversely, you may check the Autokey box below
the Key field.
Enable Autokey: Click the check box to enable/disable Autokey. See "NTP
Autokey" on the facing page for more information on Autokey.
