3. Select Details.
   The Statistics > Wireless Client > Details screen is displayed.

   

   Wireless Client Detailed Statistics Screen

   

   The Wireless Client field displays the following:

   SSID	Displays the client's SSID.
   Hostname	Lists the hostname assigned to the client when initially managed by the controller, service platform or access point managed network.
   Device Type	Displays the client device type providing the details to the operating system.
   RF Domain	Displays the RF Domain to which the connected client is a member via its connected access point, controller or service platform. The RF Domain displays as a link that can be selected to display RF Domain member, configuration and network address information in greater detail.
   OS	Lists the client‘s operating system (Android, etc.).
   Browser	Displays the browser type used by the client to facilitate its wireless connection.
   Type	Lists the client manufacturer (or vendor).
   Role	Lists the client‘s defined role in the controller, service platform or access point managed network.
   Role Policy	Lists the user role set for the client as it became a controller, service platform or access point managed device.
   Client Identity	Displays the unique vendor identity (Android, Windows, etc.) of the listed device as it appears to its adopting controller or service platform.
   Client Identity Precedence	Lists the numeric precedence this client uses in establishing its identity amongst its peers.
   Protected Management Frames	A green checkmark defines management frames as protected between this client and its associated access point radio. A red X states that management frames are disabled for the client and its connected radio.
   Transmit Power Management	Lists the number power management frames exchanged between this client and its connected access point radio. Lists zero when disabled.

   The User Details field displays the following:

   Username	Displays the unique name of the administrator or operator managing the client's connected access point, controller or service platform.
   Authentication	Lists the authentication scheme applied to the client for interoperation with its connected access point radio.
   Encryption	Lists the encryption scheme applied to the client for interoperation with its connected access point radio.
   Captive Portal Auth.	Displays whether captive portal authentication is enabled. When enabled, a restrictive set of access permissions may be in effect.

   The Connection field displays the following:

   Idle Time	Displays the time for which the wireless client remained idle.
   Last Active	Displays the time in seconds the wireless client was last interoperating with its connected access point.
   Last Association	Displays the duration the wireless client was in association with its connected access point.
   Session Time	Displays the duration for which a session can be maintained by the wireless client without it being dis-associated from its connected access point radio.
   SM Power Save Mode	Displays whether this feature is enabled on the wireless client. The SM (spatial multiplexing) power save mode allows an 802.11n client to power down all but one of its radios. This power save mode has two sub modes of operation: static operation and dynamic operation.
   Power Save Mode	Displays whether this feature is enabled or not. To prolong battery life, the 802.11 standard defines an optional Power Save Mode, which is available on most 80211 clients. End users can simply turn it on or off via the card driver or configuration tool. With power save off, the 802.11 network card is generally in receive mode listening for packets and occasionally in transmit mode when sending packets. These modes require the 802.11 NIC to keep most circuits powered-up and ready for operation.
   WMM Support	Displays whether WMM is enabled or not in order to provide data packet type prioritization between the access point and connected client.
   40 MHz Capable	Displays whether the wireless client has 802.11n channels operating at 40 MHz.
   Max Physical Rate	Displays the client's maximum data rate at the physical layer.
   Max User Rate	Displays the maximum client's permitted user data rate.
   MC2UC Streams	Lists the number or multicast to unicast data streams detected.

   The Association field displays the following:

   AP	Displays the MAC address of the wireless client's connected access point.
   BSS	Displays the BSS (Basic Service Set) the access point belongs to. A BSS is a set of stations that can communicate with one another.
   Radio Number	Displays the access point radio number the wireless client is connected to.
   Radio Type	Displays the radio type. The radio can be 802.11b, 802.11bg, 802.11bgn, 802.11a or 802.11an.
   Rate	Displays the permitted data rate for controller managed access point and client interoperation.

   The 802.11 Protocol field displays the following:

   High-Throughput	Displays whether high throughput is supported. High throughput is a measure of successful packet delivery over a communication channel.
   RIFS	Displays whether RIFS is supported. RIFS is a required 802.11n feature that improves performance by reducing the amount of dead time between OFDM transmissions.
   Negotiated Fast BSS Transition	Lists whether Fast BSS transition is negotiated. This indicates support for a seamless fast and secure client handoff between two access points, controllers or service platforms.
   Unscheduled APSD	Displays whether APSD is supported. APSD defines an unscheduled service period, which is a contiguous period of time during which the access point is expected to be awake.
   AID	Displays the AID (Association ID) established by an AP. 802.11 association enables the access point to allocate resources and synchronize with a client. A client begins the association process by sending an association request to an access point. This association request is sent as a frame. This frame carries information about the client and the SSID of the network it wishes to associate. After receiving the request, the access point considers associating with the client, and reserves memory space for establishing an AID for the client.
   Max AMSDU Size	Displays the maximum size of AMSDU. AMSDU is a set of Ethernet frames to the same destination that are wrapped in a 802.11n frame. This values is the maximum AMSDU frame size in bytes.
   Max AMPDU Size	Displays the maximum size of AMPDU. AMPDU is a set of Ethernet frames to the same destination wrapped in an 802.11n MAC header. AMPDUs are used in noisy environments to provide reliable packet transmission. This value is the maximum AMPDU size in bytes.
   Interframe Spacing	Displays the time interval between two consecutive Ethernet frames.
   Short Guard Interval	Displays the guard interval in micro seconds. Guard intervals prevent interference between data transmissions. The guard interval is the space between characters being transmitted. The guard interval eliminates ISI (inter-symbol interference). ISI occurs when echoes or reflections from one character interfere with another character. Adding time between transmissions allows echo's and reflections to settle before the next character is transmitted. A shorter guard interval results in shorter character times which reduces overhead and increases data rates by up to 10%.
