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.
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,
