4.6 Configuring Network Time Protocol (NTP)
Network Time Protocol (NTP) manages time and/or network clock synchronization in the access point-
managed network environment. NTP is a client/server implementation. The access point (an NTP
client) periodically synchronizes its clock with a master clock (an NTP server). For example, the access
point resets its clock to 07:04:59 upon reading a time of 07:04:59 from its designated NTP server.
Time synchronization is recommended for the access point’s network operations. For sites using
Kerberos authentication, time synchronization is required. Use the
Date and Time Settings screen
to enable NTP and specify the IP addresses and ports of available NTP servers.
To manage clock synchronization on the access point:
1. Select System Configuration - > Date/Time from the access point menu tree.
NOTE The current time is not set accurately when initially connecting to the
access point. Until a server is defined to provide the access point the
correct time, or the correct time is manually set, the access point displays
1970-01-01 00:00:00 as the default time.
CAUTION If using the Radius time-based authentication feature to authenticate
access point user permissions, ensure UTC has been selected from
the Date and Time Settings screen’s 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 6-76 .
