This screen enables the user to manually enter the access point’s system time using a
Year-Month-Day HH:MM:SS format.
This option is disabled when the Enable NTP checkbox has been selected, and therefore
should be viewed as a second means to define the access point system time.
4. If using the Manual Date/Time Setting screen to define the access point’s system time, refer to
the Time Zone field to select the time used to use as complimentary information to the
information entered within the Manual Date/Time Setting screen.
CAUTION
If using the Radius time-based authentication feature to authenticate access point user
permissions, ensure UTC has been selected from the Time Zone field. If UTC is not selected, time
based authentication will not work properly. For information on configuring Radius
time-based authentication, see Defining User Access Permissions by Group on page 6-248.
5. If using an NTP server to supply system time to the access point, configure the NTP Server
Configuration field to define the server network address information required to acquire the
Mobility 7131 Access Point network time.
6. Click Apply to save any changes to the Date and time Settings screen. Navigating away from
the screen without clicking the Apply button results in all changes to the screen being lost.
7. Click Undo Changes (if necessary) to undo any changes made. Undo Changes reverts the
settings displayed on Date and Time Settings screen to the last saved configuration.
8. Click Logout to securely exit the Mobility 7131 Access Point Access Point applet. A prompt
displays confirming the logout before the applet is closed.
Enable NTP on
Mobility 7131
Access Point
Select the Enable NTP on Mobility 7131 Access Point checkbox to allow a connection
between the Mobility 7131 Access Point and one or more specified NTP servers. A
preferred, first alternate and second alternate NTP server cannot be defined unless this
checkbox is selected.
Disable this option (uncheck the checkbox) if Kerberos is not in use and time
synchronization is not necessary. This option is disabled by default.
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 Mobility 7131 Access Point 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.
