• Out of Service Rate (%)—Percentage of time the AP is unavailable.
• Association Congestion Rate (%)—Association congestion rate of the AP, which is the ratio of
client association failures to the total number of association requests.
• Client Dropping Rate (%)—Client dropping rate of the AP, which is the ratio of abnormal logoffs
to the total number of clients associated with the AP.
Worst AP statistics report
This report displays statistics about the worst APs, including the peak online client number, peak
transmission rate, out of service rate, association congestion rate, and client dropping rate.
To view a worst AP statistics report, configure the following parameters:
• Parameter "Begin Time and End Time"—Select a statistics collection time range from the list. You
can select a specific time range, such as Last Hour, Last Day, Last Week, or Last Month, or
select Custom Range, and then specify the start time and end time manually.
• Location—Select a specific location view for statistics collection, or select All AP Devices.
• Begin Time/End Time—These two parameters appear only when you select Custom Range. Click
the field next to Begin Time/End Time to select the start time/end time from the calendar that
appears, in the format of YYYY-MM-DD hh:mm. The end time must be later than the start time.
• Out of Service Rate—Specify the out of service rate threshold for the AP. An AP is classified as a
worst AP when its out of service rate reaches the specified threshold. Click Save to save it as the
default value.
• Relevant Blocking Rate—Specify the relevant blocking rate threshold for the AP. An AP is
considered as worst when its relevant blocking rate is equal to or greater than the specified
threshold. The value range is 0.0 to 100.0, and the default is 5%. Click Save to save it as the
default value.
• Dropping Rate—Specify the dropping rate threshold for the AP. An AP is considered as worst
when its dropping rate reaches the specified threshold. The value range is 0.0 to 100.0, and the
default is 3%. If you enter "-1", the parameter is not used as a condition for generating the worst
AP statistics report. Click Save to save it as the default value.
The Out of Service Rate, Relevant Blocking Rate, and Dropping Rate conditions for determining
a worst AP are in "OR" relations. That is, an AP is considered as worst as long as it meets any
of the three conditions. Click Save next to Out of Service Rate, Relevant Blocking Rate, and
Dropping Rate to save the current settings as the default for subsequent accesses.
