Access Point Health

To assess access point network health:

1. Expand the System node to display RF domains.
2. Select and expand an RF domain to expose its member controllers or service platforms.
3. Select a controller or service platform and expand the menu item to display connected access points.
4. Select an access point. The Health tab displays by default.
   The Device Detail field displays the following information about the selected access point:

   • Hostname - Lists the administrator assigned name of the selected access point.
   • Device MAC - Lists the factory encoded MAC address of the selected access point.
   • Primary IP Address - Lists the IP address assigned to the access point as a network identifier.
   • Type - Indicates the access point model type. An icon representing the access point is displayed along with the model number
   • RF Domain Name - Lists the RF Domain to which the access point belongs. The RF Domain displays as a link that can be selected to display access point RF Domain membership data in greater detail.
   • Model Number - Lists the specific model number of the access point.
   • Version - Lists the version of the firmware running on the access point. Compare this version against the version currently on the support site to ensure the access point has the latest feature set available.
   • Uptime - Displays the duration the access point has been running from the time it was last restarted.
   • CPU - Displays the CPU installed on this access point.
   • RAM - Displays the amount of RAM available for use in this system.
   • System Clock - Displays the current time on the access point.

   The Radio RF Quality Index displays a table of RF quality per radio. It is a measure of the overall effectiveness of the RF environment displayed in percentage. It is a function of the connect rate in both directions, the retry rate and error rate. The quality is measured as:

   • 0-20 - Very poor quality
   • 20-40 - Poor quality
   • 40-60 - Average quality
   • 60-100 - Good quality

   The Radio Utilization Index area displays how efficiently the RF medium is used. Radio utilization is defined as the percentage of current throughput relative to the maximum possible throughput for the radio. The Radio Utilization displays radios in terms of the number of associated wireless clients and percentage of utilization. It also lists packets types transmitted and received.

   The Client RF Quality Index displays a table of RF quality on a per client basis. It is a measure of the overall effectiveness of the RF environment displayed in percentage. It is a function of the connect rate in both directions, the retry rate and the error rate. This area of the screen displays the average quality index for a client. The table lists the bottom five (5) of the RF quality values by client. The quality is measured as:

   • 0-20 - Very poor quality
   • 20-40 - Poor quality
   • 40-60 - Average quality
   • 60-100 - Good quality
