Using Web Management to Configure SNTP

Simple Network Time Protocol (SNTP) allows the RBT‐4102 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.
The RBT‐4102 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.
To configure SNTP, select System Log from the menu, and scroll down to SNTP Server.
• 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
Note: If SNTP is disabled, you can manually set the date and time of the system clock.
– Set Time (SNTP Server disabled) allows you to manually set the current date and time for
the location of this access point.
• Set Time Zone. SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean
Time, or GMT) based on the time at the Earth's prime meridian, zero degrees longitude.
– Enter Time Zone sets a time corresponding to your local time. You must indicate the
number of hours your time zone is located before (East) or after (West) UTC.
– 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.
