“Access Point Statistics”
Network Time Protocol (NTP) is central to networks that rely on their access point(s) to supply system
time. Without NTP, access point supplied network time is unpredictable, which can result in data loss,
failed processes, and compromised security. With network speed, memory, and capability increasing at
an exponential rate, the accuracy, precision, and synchronization of network time is essential in an
access point managed enterprise network. The access point can use a dedicated server to supply system
time. The access point can also use several forms of NTP messaging to sync system time with
authenticated network traffic.
The Network Time screen provides detailed statistics of an associated NTP Server of an access point.
Use this screen to review the statistics for each access point.
