indication message. It is related to beacon interval. RTS Threshold: The Request to Send (RTS) threshold is the value the AP checks against its transmitting frames to determine if the RTS/Clear To Send (CTS) handshake is required with the receiving client. Using a small value causes RTS packets to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of the network packet. The default is 2346, which effectively disables RTS. Frag Threshold: This is the maximum length of the frame, beyond which packets must be broken up (fragmented) into two or more frames. Collisions occur more often for long frames because sending them occupies the channel for a longer time. The default is 2346, which effectively disables Fragmentation. Preamble Mode: 802.11b requires that a preamble be prepended to every frame before it is transmitted to the air. The preamble may be either the traditional long preamble, which requires 192 micro second for transmission, or it may be an optional short preamble that requires only 96 micro second. Long preamble is needed for the compatibility with legacy 802.11 systems operating at 1 and 2 Mbps. The default is 'long'. RTS/CTS Protection: If selected the AP always performs RTS/CTS handshake before transmitting a packet. It is generally used to minimize collisions among hidden stations Transmit Power Gain: Defines the relative amplification (gain) in dbm for transmitted packets which is added to the TX power configured on the physical radio. Retry Limit: The number of retries the AP will use when a frame transmission fails. It is used for both long and short frames, of size less than or equal to the RTS threshold. Supported Rate: The rate or rates (in Mbps) which the AP will advertise in the beacon frames. Displays Profile configuration. If no profile name is specified, this command will display a 3 show dot11 profile summary of the details of all the profiles configured in the system. If a profile name is specified, this command will display a detailed configuration of the profile. If the argument 'DisplayQosInfo' is set to 'Y', the profile details will include the QoS details as well. 18
