Configuring SNTP
Simple Network Time Protocol (SNTP) allows the access point to set its
internal clock based on periodic updates from a time server (SNTP or NTP).
Maintaining an accurate time on the access point enables the system log to
record meaningful dates and times for event entries. If the clock is not set, the
access point will only record the time from the factory default set at the last
bootup.
The access point acts as an SNTP client in unicast mode, 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 is enabled by default. The access point also allows you to disable SNTP
and set the system clock manually.
Setting the 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. To display a time corresponding to
your local time, you must indicate the number of hours and minutes your time
zone is east or west of UTC.
Web: Setting SNTP Parameters
The System Servers window on the Administration tab enables SNTP server and
time zone details to be configured for the access point.
The web interface enables you to modify these parameters:
SNTP Server: Configures the access point to operate as an SNTP unicast
■
client. When enabled, at least one time server IP address must be speci-
fied.
•
Primary Server: The IP address of an SNTP or NTP time server that
the access point attempts to poll for a time update.
•
Secondary Server: The IP address of a secondary SNTP or NTP 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.
■
Set Time Zone: Selects the time zone that specifies the number of hours
before (east) or after (west) UTC.
