RF Domain Health

The Health tab displays the status of the RF domain‘s device membership.

To assess the RF domain component health:

1. Expand the System node to display RF domains.
2. Select an RF domain. The Health tab displays by default.

   Refer to the following RF domain health information for member devices:

   • The Domain field lists the RF domain manager reporting utilization statistics. The MAC address displays as a link that can be selected to display RF domain information in at more granular level.
   • The Devices field displays the total number of devices and the status of the devices in the network as a graph. This area displays the total device count managed by this device and their status (online vs. offline) as a pie graph.
   • The Radio Quality table displays 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 transmit retry rate in both directions and the error rate. This area of the screen displays the average quality index across all the defined RF domain on the wireless controller. The table lists worst five of the RF quality values of all the radios defined on the wireless controller. The quality is measured as:
     • 0-20 - Very poor quality
     • 20-40 - Poor quality
     • 40-60 - Average quality
     • 60-100 - Good quality
3. Select a Radio Id to view all the statistics for the selected radio in detail.
   The Client Quality table displays RF quality for the worst five performing clients. It is a function of the transmit retry rate in both directions and the error rate. This area of the screen displays the average quality index across all the defined RF domain on the wireless controller. 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 client to view its statistics in greater detail.
   • WLAN Utilization displays how efficiently the WLANs are used. Traffic utilization is defined as the percentage of current throughput relative to the maximum possible throughput for the WLAN. The total number of WLANs is displayed above the table. The table displays a list of the top five WLANs in terms of overall traffic utilization. It displays the utilization level names, WLAN name and SSIDs for each of the top five WLANs.
   • Radio Traffic Utilization displays how efficiently the RF medium is used. Traffic utilization is defined as the percentage of current throughput relative to the maximum possible throughput for the RF domain. The Traffic Index area displays an overall quality level for radio traffic and the Max User Rate displays the maximum data rate of associated radios. The table displays a list of the top five radios in terms of overall traffic utilization quality. It displays the radio names, MAC Addresses and radio types for each of the top five radios.
   • Client Traffic Utilization displays how efficiently the RF medium is utilized for connected clients. Traffic utilization is defined as the percentage of current throughput relative to the maximum possible throughput for the clients in the RF domain. The table displays a list of the top five performing clients in respect to overall traffic utilization. It displays the client names, MAC Addresses and vendor for each of the top five clients.
   • Wireless Security displays the overall threat index for the system. This index is based on the number of Rogue/Unsanctioned APs and Wireless Intrusion Protection System (WIPS) events detected. The index is in the range 0 - 5 where 0 indicates there are no detected threats. An index of 5 indicates a large number of intrusion detection events or rogue/unsanctioned APs detected.
   • Traffic Statistics include transmit and receive values for Total Bytes, Total Packets, User Data Rate, Broadcast/Multicast Packets, Management Packets, Tx Dropped Packets and Rx Errors.
