Basic Configuration
NTPEnable: When enabled, the VMR or NPS will contact an NTP server (defined
via the NTP Address prompts) once a day, and update its clock based on the NTP
server time and selected Time Zone. (Default = Off.)
Notes:
The VMR/NPS will also contact the NTP server and update the time whenever
you change NTP parameters.
To cause VMR or NPS to immediately contact the NTP server at any time,
make certain that the NTP feature is enabled and configured, then type /F
and press [Enter]. When the System Parameters menu appears, press
[Esc]. The VMR or NPS will save parameters and then attempt to contact the
server, as specified by currently defined NTP parameters.
PrimaryNTPAddress: Defines the IP address or domain name (up to 64
characters long) for the primary NTP server. (Default = undefined.)
Note: In order to use domain names for web addresses, DNS parameters must
first be defined as described in Section 5.9.5.
SecondaryNTPAddress: Defines the IP address or domain name (up to 64
characters long) for the secondary, fallback NTP Server. (Default = undefined.)
Note: In order to use domain names for web addresses, DNS parameters must
be defined as described in Section 5.9.5.
NTPTimeout: The amount of time in seconds, that will elapse between each
attempt to contact the NTP server. When the initial attempt is unsuccessful, the
VMR/NPS will retry the connection four times. If neither the primary nor secondary
NTP server responds, the VMR/NPS will wait 24 hours before attempting to contact
the NTP server again. (Default = 3 Seconds.)
TestNTPServers: (Text Interface Only) Allows you to ping the IP addresses or
domain names defined via the Primary and Secondary NTP Address prompts, or to
ping a new address or domain defined via the Test NTP Servers submenu in order
to check that a valid IP address or domain name has been entered.
Note: In order for the Test NTP Servers feature to function, your network and/or
firewall must be configured to allow ping commands.
