AP NTP Status

To view an access point's NTP Status:

1. Select the Statistics menu from the Web UI.
2. Expand the System node from the navigation pane (on the left-hand side of the screen). The System node expands to display the RF Domains created within the managed network.
3. Expand an RF Domain node, select a controller or service platform, and select one of its connected access points. The access point's statistics menu displays in the right-hand side of the screen, with the Health tab selected by default.
4. Expand the Network Time menu
   The Statistics > AP > Network Time > NTP Status screen displays by default.

   

   

   Use this screen to review the accuracy and performance of the synchronization with a NTP server resource.

   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.
   Precision	Displays the precision of the time clock (in Hz). The values that normally appear in this field range from -6, for mains-frequency clocks, to -20 for microsecond clocks.
   Reference Time	Displays the time stamp the access point‘s clock was last synchronized or corrected.
   Reference	Displays the address of the time source the access point is synchronized to.
   Root Delay	The total round-trip delay in seconds. This variable can take on both positive and negative values, depending on relative time and frequency offsets. The values that normally appear in this field range from negative values (a few milliseconds) to positive values (several hundred milliseconds).
   Root Dispersion	The difference between the time on the root NTP server and its reference clock. The reference clock is the clock used by the NTP server to set its own clock.
   Stratum	Displays how many hops the access point is from its current NTP time resource.
