Safran VersaSync - Checklist NTP Configuration; The NTP Setup Screen

These features include the ability to use either MD5 authentication or NTP
Autokey, to block NTP access to parts of the network and to broadcast NTP data
to the network’s broadcast address. NTP and SNTP are used to synchronize time
on any computer equipment compatible with the Network Time Protocol. This
includes Cisco routers and switches, UNIX machines, and Windows machines
with suitable clients. To synchronize a single workstation, several freeware or
shareware NTP clients are available on the Internet. The software running on the
PC determines whether NTP or SNTP is used.
When the NTP service is enabled, VersaSync will “listen” for NTP request mes-
sages from NTP clients on the network. When an NTP request packet is received,
VersaSync will send an NTP response time packet to the requesting client. Under
typical conditions, VersaSync can service several thousand NTP requests per
second without MD5 authentication enabled, and at a somewhat lower rate with
MD5 authentication enabled.
You can either enable or completely disable the NTP Service. When NTP is dis-
abled, no NTP time packets will be sent out to the network. When enabled, by
default, the NTP Service operates in Unicast mode, i.e. the NTP Service responds
to NTP requests only.
Note: In order to configure NTP, you need to access the NTP Setup
screen which requires ADMINISTRATORrights.
2.8.11.1 Checklist NTP Configuration
The following is a list of configuration settings you may want to consider as you
setup your NTP Service. (Not all items may apply to your application, or there
may be other considerations not included in this list.)
1. Did you setup your NTP Service and have it use the right Reference(s)?
See "NTP Reference Configuration" on page115.
2. Does your NTP Service use the right Timescale?
See "NTP Output Timescale" on page114.
3. If required, have you setup other NTP Servers and Peers for fallback pur-
poses?
See "NTP Peers: Adding, Configuring, Removing" on page123.
2.8.11.2 The NTP Setup Screen
