Configuring SNTP
Simple Network Time Protocol (SNTP) allows the Access Point 3000 to set its internal clock based
on periodic updates from a time server. Maintaining an accurate time on the access point enables
the system log to record meaningful dates and times for event entries.
on periodic updates from a time server. Maintaining an accurate time on the access point enables
the system log to record meaningful dates and times for event entries.
The Access Point 3000 acts as an SNTP client, periodically sending time synchronization requests
to specific time servers. You can configure up to two time server IP addresses. The access point
will attempt to poll each server in the configured sequence.

SNTP Server configures the access point to operate as an SNTP client. When enabled, at least
one time server IP address must be specified. When disabled, you manually set the date and
time of the system clock.

Primary Server is the IP address of an SNTP time server that the access point attempts to
poll for a time update. Default: 137.92.140.80

Secondary Server is the IP address of a secondary SNTP time server. The access point first
attempts to update the time from the primary server; if this fails it attempts an update
from the secondary server. Default: 192.43.244.18

Enable Daylight Saving provides a way to automatically adjust the system clock for
Daylight Savings Time changes. To use this feature you must define the month and date to
begin and to end the change from standard time. During this period the system clock is set
back by one hour.
