4. Click Apply to save any changes to the NTP Servers screen. Navigating away from the
screen without clicking the Apply button results in all changes to the screen being lost.
5. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the
settings displayed on NTP Servers screen to the last saved configuration.
6. Click Logout to securely exit the AP-5131 Symbol Access Point applet. A prompt displays
confirming the logout before the applet is closed.
4.6 Logging Configuration
The AP-5131 provides the capability for periodically logging system events that prove useful in
assessing the throughput and performance of the AP-5131 or troubleshooting problems on the
AP-5131 managed Local Area Network (LAN). Use the Logging Configuration screen to set the
desired logging level (standard syslog levels) and view or save the current AP-5131 system log.
To configure event logging for the AP-5131:
1. Select System Configuration - > Logging Configuration from the AP-5131 menu tree.
Enable NTP on
AP-5131
Select the Enable NTP on AP-5131 checkbox to allow a
connection between the
AP-5131 and one or more specified NTP
servers.
Disable this option (uncheck the checkbox) if Kerberos is not in use
and time synchronization is not necessary.
Preferred Time Server Specify the
numerical (non DNS name) IP address and port of the
primary NTP server. The default port is 123.
First Alternate Time
Server
Optionally, specify the
numerical (non DNS name) IP address and
port of an alternative NTP server to use for time synchronization if
the primary NTP server goes down.
Second Alternate
Time Server
Optionally, specify the
numerical (non DNS name) and port of yet
another NTP server for the greatest assurance of uninterrupted
time synchronization.
Synchronization
Interval
Define an interval in minutes the
AP-5131 uses to synchronize its
system time with the NTP server. A synchronization interval value
from 15 minutes to 65535 minutes can be specified. For
implementations using Kerberos, a synchronization interval of 15
minutes (default interval) or sooner is recommended.
