will have access to VersaSync. If you select “allow”, the con-
figured portion of the network will have NTP access to Ver-
saSync, but the rest of the network will not have access to
VersaSync. By default, VersaSync allows all IPv4 and IPv6 con-
nections.

2.8.11.11 NTP Expert Mode
Advanced NTP configuration is possible via the NTP Expert Mode, which allows
you to write directly into the NTP.conf file (the syntax is similar to the one used
with CISCO routers).
Caution: NTP Expert Mode should only be utilized by advanced
users, as incorrectly altering the NTP.conf file can cause NTP to stop
working (if NTP is configured as an input reference, VersaSync could
lose synchronization).
To access the NTP Expert Mode, navigate to MANAGEMENT > NTP Setup. The
switch for the NTP Expert Mode is in the panel NTP Services.
Caution: Any configurations made in NTP Expert Mode will be lost as
soon as NTP Expert Mode is disabled.
