Controller Device

The Device screen provides detailed information about the selected device within the controller, service platform managed system.

To view system device statistics:

Select the Statistics tab from the Web UI.
Expand the System node on the top, left-hand side of the screen. The System node expands to display the RF Domains created within the managed network.
Expand an RF Domain node, and select one its connected Wireless Controller/Service Platform.

Number	Displays the number of fans supported on the this controller or service platform.
Speed (Hz)	Displays the fan speed in Hz.

The Temperature field displays the following:


Number	Displays the number of temperature elements (gauges) utilized by the selected device (controller or service platform).
Temperature	Displays the current temperature (in Celsius) to assess a potential overheat condition.

The Kernal Buffers field displays the following:


Buffer Size	Lists the sequential buffer size.

Primary Install Date	Displays the date this firmware version was installed on the controller or service platform.
Primary Version	Displays the primary version string.
Secondary Build Date	Displays the build date when this secondary version was created.
Secondary Install Date	Displays the date this secondary version was installed on the controller or service platform.
Secondary Version	Displays the secondary version string.
FGPA Version	Displays the FGPA version string.
PoE Firmware Version	Displays the version of the PoE (Power Over Ethernet) firmware if the PoE feature is available.

The AP Licenses field displays the following license information for access points:


AP Licenses	Displays the number of AP licenses currently available on the controller or service platform. This value represents the maximum number of licenses the controller or service platform can adopt.
AP Adoptions	Displays the number of APs adopted by this controller or service platform.
AP License	Displays the license string of the AP.

The AAP Licenses field displays the following license information for adaptive access points:


AAP Licenses	Displays the number of AAP (adaptive access point) licenses currently available. This value represents the maximum number of licenses the controller or service platform can adopt.
AAP Adoptions	Displays the number of AAPs adopted by this controller or service platform.
AAP License	Displays the license string of the AAP.

The Additional Licenses area displays the following information:


ADSEC	Displays the number of Advanced Security licenses. This enables the Role Based firewall and increases the number of IP Sec VPN tunnels. The maximum number of IP Sec VPN tunnels varies by platform.
WIPS	Displays the number of WIPS licenses utilized by the controller or service platform.
Hotspot Analytics	Displays whether an advanced hotspot analytics license is in use and applied to the controller or service platform.

The IP Name Servers table displays the following:


Name Server	Displays any custom Name Server mappings on the controller or service platform.
Type	Displays the type of DNS mapping, if any, on the controller or service platform.

The IPv6 Name Servers table displays the following:


Name Server	Displays any custom IPv6 formatted IP address Name Server mappings on the controller or service platform.
Type	Displays the type of DNS mapping, if any, on the controller or service platform.

The IPv6 Hop Limit table displays the following:


Hop Limit	Lists the maximum number of times IPv6 traffic can hop. The IPv6 header contains a hop limit field that controls the number of hops a datagram can be sent before being discarded (similar to the TTL field in an IPv4 header).

The IPv6 Delegated Prefixes field displays the following:


IPv6 Delegated Prefix	If IPv6, prefix delegation is used to assign a network address prefix, configuring the controller or service platform with the prefix.
