Modifying Ntp Server Or Date And Time - HP HPE VAN SDN Controller 2.7 Administrator's Manual

Modifying NTP server or date and time

You can configure one NTP server or set a specific date and time for the controller system. It is
recommended that you use an NTP server rather than setting date and time because if you
change network settings, the date/time will be reset to current date/time.
If the controller is in a team and you want to change the NTP server or date and time, the other
two controllers in the team must have the same NTP server or date and time. You can make the
change on an individual controller but will see a message reminding you to check that the NTP
server or date and time is the same on the other controllers in the team.
NOTE: You can also use the python script /opt/sdn/scripts/postinstall/
config_sdn.py to configure NTP servers or the date and time on a controller. For details on
using this script, see the HPE VAN SDN Controller Installation Guide.
