The NTP Association screen displays the following:
13.3.30 Load Balancing
Access Point Statistics
An access point load can be viewed in a graph and filtered to display different load attributes. The access point’s entire load
can be displayed, as well as the separate loads on the 2.4 and 5 GHz radio bands. The channels can also be filtered for display.
Each element can either be displayed individually or collectively in the graph.
To view the access point’s load balance in a filtered graph format:
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 Load Balancing.
Delay Time Displays the round-trip delay (in seconds) for broadcasts between the NTP server and the
access point.
Display Displays the time difference between the peer NTP server and the access point’s clock.
Offset Displays the calculated offset between the access point and the NTP server. The access point
adjusts its clock to match the server’s time value. The offset gravitates towards zero, but never
completely reduces its offset to zero.
Poll Displays the maximum interval between successive messages (in seconds) to the nearest
power of two.
Reach Displays the status of the last eight SNTP messages. If an SNTP packet is lost, the lost packet
is tracked over the next eight SNTP messages.
Reference IP
Address
Displays the address of the time source the access point is synchronized to.
Server IP Address Displays the numerical IP address of the SNTP resource (server) providing SNTP updates to the
access point.
State Displays the NTP association status. This can be one of the following:
• Synced - Indicates the access point is synchronized to this NTP server.
• Unsynced - Indicates the access point has chosen this master for synchronization. However,
the master itself is not yet synchronized to UTC.
• Selected - Indicates this NTP master server will be considered the next time the access
point chooses a master to synchronize with.
• Candidate - Indicates this NTP master server may be considered for selection the next time
the access point chooses a NTP master server.
• Configured - Indicates this NTP server is a configured server.
Status Displays how many hops the access point is from its current NTP time source.
Time Displays the time of the last statistics update.
Refresh Select the Refresh button to update the screen’s statistics counters to their latest values.
