Controller Health

To assess the controller or service platform‘s 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. The Health tab displays by default.

   Refer to the Device Details table for information about the selected controller or service platform The following information is displayed:

   • Hostname - Lists the administrator assigned name of the controller or service platform.
   • Device MAC - Lists the factory encoded MAC address of the controller or service platform.
   • Type - Indicates the type of controller or service platform. An icon representing the RFS controller or NX service platform device type is displayed along with the model number.
   • RF Domain Name - Lists the RF domain to which the controller or service platform belongs. The RF Domain displays as a link that‘s selectable to display RF Domain data in greater detail.
   • Model Number - Lists the model number and hardware SKU information of the selected controller or service platform to refine its intended deployment region.
   • Version - Lists the firmware version currently running on the controller or service platform. Compare this version against the version currently on the support site to ensure the controller or service platform has the latest feature set available.
   • Uptime - Displays the duration the controller or service platform has been running since it was last restarted.
   • CPU - Displays the CPU installed on this controller or service platform.
   • RAM - Displays the amount of RAM available for use in this system.
   • System Clock - Displays the current time set on the controller or service platform.

   The Adopted Devices Health (w/ cluster members) displays a graph of access points in the system with the available access points in green and unavailable access points in red.

   Radio RF Quality Index provides a table of RF quality on a per radio 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. The screen displays the average quality index within the access point single radio. The table lists the bottom five (5) of the RF quality values by access point radio. The quality is measured as:

   • 0-20 - Very poor quality
   • 20-40 - Poor quality
   • 40-60 - Average quality
   • 60-100 - Good quality
4. Select a Radio Id to view statistics in greater detail. The Radio Utilization table 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 table displays the access point radios in terms of the number of associated wireless clients and the percentage of utilization. It also displays a table of 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 a client. Quality is measured as:

   • 0-20 - Very poor quality
   • 20-40 - Poor quality
   • 40-60 - Average quality
   • 60-100 - Good quality
5. Select a client MAC to view all the statistics for the selected client in greater detail.
