The
NTP Server
Edit window displays. Enter the required information:
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 configured
on both the NetClock and the NTP Peer or NTP Server. If the Symmetric Key-
ID/Key string pair method is selected the Key-ID must be first defined on the Sym
metric Key page.
Enable Symmetric Key
: Click to enable Symmetric Key, and then select an option
from the drop down menu that displays.
Note:
Before you can choose an option in the
Key
field, you must
first set up symmetric keys through the
Actions
panel. See
"Con
figuring NTP Symmetric Keys" on page 118
. Conversely, you may
check the
Autokey
box below the
Key
field.
Enable Autokey
: Click here if you want to use Autokey with this server. See "NTP
Autokey" on page 112.
