The Association field displays the following:
The 802.11 Protocol field displays the following:
Traffic
The traffic screen provides an overview of client traffic utilization in both the transmit and receive
directions. This screen also displays a RF quality index.
To view the traffic statistics of a wireless clients:
1. Select the Statistics menu from the Web UI.
AP
Displays the MAC address of the client’s connected Access Point.
BSS
Displays the Basic Service Set (BSS) 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 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 Access Point and client interoperation.
High-Throughput
Displays whether high throughput is supported. High throughput is a measure of the successful packet
delivery over a communication channel.
RIFS
Displays whether this feature is supported. RIFS is a required 802.11n feature that improves
performance by reducing the amount of dead time between OFDM transmissions.
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.
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.
AID
Displays the Association ID (AID) 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 that
are wrapped in an 802.11n MAC header. AMPDUs are used in a very noisy environment to provide
reliable packet transmission. This value is the maximum AMPDU size in bytes.
Interframe Spacing
Displays the 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 inter-symbol interference (ISI). 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%.
