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.
The Network Time statistics screen consists of two tabs:
• NTP Status
• NTP Association
13.3.32.1 NTP Status
Network Time
To view the Network Time statistics of an access point:
1. Select the Statistics menu from the Web UI.
2. Select System from the navigation pane (on the left-hand side of the screen). Expand a RF Domain and select one of its
connected access points.
3. Select Network Time.
Figure 13-104 Access Point - NTP Status screen
The NTP Status tab displays by default with the following information:
Clock Offset Displays the time differential between the access point’s time and its NTP resource’s time.
Frequency Indicates the SNTP server clock’s skew (difference) for the access point.
Leap Indicates if a second is added or subtracted to SNTP packet transmissions, or if transmissions
are synchronized.
