NTP
Use the Network Time Protocol to synchronize the network time based on Greenwich Mean Time
(GMT). If using the NTP mode, users can ma nually set up to 5 NTP servers. The switch syncs the time
in a short time after pressing the
Apply
button. Though it synchronizes the time automatically, NTP
does not update the time periodically without user’s processing.
Time Zone is an offset time off GMT. Select the time zone first, and then do a time sync via NTP. The
switch combines this time zone offset and updated NTP time to calculate the local time; otherwise, the
time is incorrect. The switch supports configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.
To configure Time in the web interface:
1. Navigate to System > Time > NTP .
2. Specify the NTP server address (es).
3. Click
Apply . 0.
