CHAPTER 4: SYSTEM CONFIGURATION
Enter Time Zone – Sets the desired time zone + or - GMT.
Enable Daylight Saving – Adjusts the clock for summertime and wintertime.
The system allows you to limit the messages that are logged by specifying a
minimum severity level. The following table lists the error message levels from the
most severe (Emergency) to least severe (Debug). The message levels that are
logged include the specified minimum level up to the Emergency level.
Table 3 Logging Levels
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, 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.
 Primary Server: The IP address of an SNTP or NTP time server that the access
point attempts to poll for a time update.
Error Level Description
Emergency System unusable
Alerts Immediate action needed
Critical Critical conditions (e.g., memory allocation, or free memory error - resource
exhausted)
Error Error conditions (e.g., invalid input, default used)
Warning Warning conditions (e.g., return false, unexpected return)
Notice Normal but significant condition, such as cold start
Informational Informational messages only
Debug Debugging messages
NOTE: The access point error log can be viewed using the Event Logs window in
the Status section (
page 4-61). The Event Logs window displays the last 128
messages logged in chronological order, from the newest to the oldest. Log
messages saved in the access point’s memory are erased when the device is
rebooted.
