Configuration of the individual server/peer address is as follows:
1. Insert time sources (IP-address or Name e.g. “ntp.metas.ch”
ENTER without entry of an address will delete value.
2.-3. Configurations of
Minpoll
and
Maxpoll
: Inquiry interval 2^
poll value
in seconds.
0 = automatically
e.g. poll value=2
 intervall 2: 2 2 = 4sec., poll value=5  intervall 5: 2 5 = 32sec.
Range of poll values (exponent): 1 – 16
To get an exact synchronization it’s better to limit Maxpoll to 6 (64 sec.).
4. Set type of inquiry: server or peer
5. Preferred source: on or off
If possible, one source should always be preferred (even if only one source is
defined), except if DCF is active.
6. Authentication key: off, key number, autokey
Important:
All changes lead to a
restart
of the NTP server!
Important:
Maxpoll should not be selected under 4 (16 sec), as otherwise, internal
trimmung may be inaccurate.
Maxpoll and Minpoll on automatic can lead to insufficient synchronization
accuracy. The specified accuracies were measured with Minpoll = 3 and
Maxpoll = 6.
The configuration server should be used as far as possible.
