Health

The Health screen displays general status information for a selected RF Domain, including data polled from all its members.

To display the collective device membership health of a controller, service platform or AP RF Domain:

1. Select the Statistics → System menu from the Web UI.
2. Select an RF Domain from the list.

   The RF Domain statistics menu displays in the right-hand side of the screen, with the Health tab selected by default.

   

   
3. Review the different fields displayed on the RF Domain > Health screen:
   • Domain - Displays the name of the RF Domain manager. The RF Domain manager is the focal point for the radio system and acts as a central registry of applications, hardware and capabilities. It also serves as a mount point for all the different pieces of the hardware system file.
   • Devices - Displays the total number of online versus offline devices in the RF Domain, and an exploded pie chart depicts their status.
   • Radio Quality - Displays information on the RF Domain's RF quality. The RF quality index is the overall effectiveness of the RF environment as a percentage of the connect rate in both directions, as well as the retry and error rate. This area also lists the worst 5 performing radios amongst all the RF Domain device member radios.
     The RF Quality Index can be interpreted as:

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

     Refer to the Radio Quality table for RF Domain member radios requiring administration to improve performance:

     Worst 5 Radios	Displays five radios with the lowest average quality in the RF Domain.
     Radio ID	Lists each radio‘s administrator defined hostname and its radio designation (radio 1, radio 2 or radio 3).
     Radio Type	Displays the radio type as either 5 GHz or 2.4 GHz.

   • Client Quality - Refer to the table below for RF Domain connected clients requiring administration to improve performance:

     Worst 5 Clients	Displays the five clients having the lowest average quality indices.
     Client MAC	Displays the hard coded radio MAC of the wireless client.
     Vendor	Displays the vendor name of the wireless client.

   • WLAN Utilization - Refer to the table below to assess WLAN related information:

     Total WLANs	Displays the total number of WLANs managed by RF Domain member access points.
     Top 5	Displays the five RF Domain utilized WLANs with the highest average quality indices.
     WLAN Name	Displays the WLAN Name for each of the Top 5 WLANs in the access point RF Domain.
     SSID	Displays the SSID for the WLAN.

   • Radio Traffic Utilization - Refer to the following table to identify radios requiring administration to improve performance:

     Max. User Rate	Displays the maximum recorded user rate in kbps.
     Top 5 Radios	Displays five radios with the best average quality in the RF Domain.
     Radio ID	Lists each radio‘s administrator defined hostname and its radio designation (radio 1, radio 2 or radio 3).
     Radio Type	Displays the radio type as either 5 GHz or 2.4 GHz.

   • Client Traffic Utilization - Refer to the following table for wireless client related information:

     Top 5 Clients	Displays the five clients having the highest average quality indices.
     Client MAC	Displays the client‘s hard coded MAC address used a hardware identifier.
     Vendor	Lists each client‘s manufacturer.

   • Wireless Security - Indicates the security of the transmission between WLANs and the wireless clients they support. This value indicates the vulnerability of the WLANs.

     RF Domain Threat Level	Indicates the threat from wireless clients trying to find network vulnerabilities within the RF Domain. The threat level is represented by an integer.
     Rogue APs	Lists the number of unauthorized APs detected by RF Domain member devices.
     WIPS Events	Lists the number of WIPS events generated by RF Domain member devices.

   • Traffic Statistics - Displays the following information for transmitted and received packets:

     Total Bytes	Displays the total bytes of data transmitted and received within the RF Domain.
     Total Packets	Lists the total number of data packets transmitted and received within the RF Domain.
     User Data Rate	Lists the average user data rate within the RF Domain.
     Bcast/Mcast Packets	Displays the total number of broadcast/multicast packets transmitted and received within the RF Domain.
     Management Packets	Displays the total number of management packets processed within the RF Domain.
     Tx Dropped Packets	Displays the total number of dropped data packets within the RF Domain.
     Rx Errors	Displays the number of errors encountered during data transmission within the RF Domain. The higher the error rate, the less reliable the connection or data transfer.

   • SMART RF Activity - Refer to the table below for details:

     Time Period	Lists the time period when Smart RF calibrations or adjustments were made to compensate for radio coverage holes or interference.
     Power Changes	Displays the total number of radio transmit power changes that have been made using SMART RF within the RF Domain.
     Channel Changes	Displays the total number of radio transmit channel changes that have been made using SMART RF within the RF Domain.
     Coverage Changes	Displays the total number of radio coverage area changes that have been made using SMART RF within the RF Domain.
