APs
This section displays the following performance details of the APs on the controller:
l Overall goodput
l Frame rate distribution of the APs
l Channel quality
l To client or from client frame rates
l Percentage of frames dropped
You can click the hyperlinked text and histograms to view the AP specific performance information as a trend
chart. Additionally, you can view the distribution of the APs in different noise floor ranges, channel utilization
ranges, and non-Wi-Fi interference ranges using the histograms. To understand histogram information, see
Using Dashboard Histograms on page 787.
Using Dashboard Histograms
Dashboard histograms are a visual representation of the distribution of the wireless clients, access points, and
radios across different performance parameters in the controller. Histograms help you to quickly identify any
performance issues in the network from the color of the distribution. For example, critical ranges of the
distribution are highlighted in red and normal ranges are highlighted in green.
You can view the number of clients or APs falling in each range of the distribution with a hyperlink. You can also
perform the following tasks on the histograms to get additional information on the clients and APs in the
distribution:
l View Client or AP details—Click the hyperlinked number to view the details of the clients or APs in a pop-
up window.
l Sort—Click a column header of the clients or APs table to sort the complete list based on the entries on the
active column. You can also use the sort icon that appears when you click on a column for sorting.
l Filter—Click the filter icon and select the filter criterion on any column to filter the entries.
l Close pop-up window—Click on the close icon to close the client or AP details pop-up window.
Usage
The Usage page displays the usage summary of the following on the controller:
l Clients & APs: The active wireless clients, status of APs, and its usage.
l Top APs: The list of APs with the number of clients on the controller. The list of APs is in the descending
order based on the number of clients associated with an AP. You can filter the APs for the 2.4 GHz and 5
GHz radio band options.
l Radios: The radios and clients connected to an AP, usage, and frame types transmitted and received by the
radio.
l Devices: The pie chart of the clients based on the device type. Clicking on the pie chart segment opens the
client details page filtered on the device type.
l AirGroup: All the AirGroup services available and number of servers offering the service. It is aggregated by
the total number of AirGroup servers sorted by the services they advertise. For more information, see
Controller Dashboard Monitoring on page 1014.
l Overall Usage: The total number of clients and APs that have the low usage and throughput data in the
last 15 minutes.
