2.8.9.11 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 syn-
chronization).
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.
NTP utilizes the NTP.conf file for its configuration. Normally, configuration of this file is
indirectly performed by a user via the integrated configuration pages of the VersaSync
Web UI. However, it may be desired in certain circumstances to edit this file directly,
instead of using the web-based setup screens. When Expert Mode is enabled, the user has
direct access to the NTP.conf file.
Caution: Orolia Tech Support does not support the editing of the NTP con-
figuration files while in the Expert Mode. For additional information on edit-
ing the NTP.conf file, please refer to http://www.ntp.org/.
