Parameter Description RX Sensitivity Tuning Based Channel Reuse Shows if the channel reuse feature's current operating mode, static, dynamic or disable. l Static: This mode of operation is a coverage-based adaptation of the Clear Channel Assessment (CCA) thresholds. In the static mode of operation, the CCA is adjusted according to the configured transmission power level on the AP, so as the AP transmit power decreases as the CCA threshold increases, and vice versa. l Dynamic: In this mode, the Clear Channel Assessment (CCA) thresholds are based on channel loads, and take into account the location of the associated clients. When you set the Channel Reuse This feature is automatically enabled when the wireless medium around the AP is busy greater than half the time. When this mode is enabled, the CCA threshold adjusts to accommodate transmissions between the AP its most distant associated client. l Disable: This mode does not support the tuning of the CCA Detect Threshold. RX Sensitivity Threshold Enable CSA CSA Count Management Frame Throttle Interval Management Frame Throttle Limit ARM/WIDS Override Reduce Cell Size (Rx Sensitivity) If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this parameter manually sets the AP's Rx sensitivity threshold (dBm). The AP will filter out and ignore weak signals that are below the channel threshold signal strength. For example, if the RX sensitivity threshold was set to -65 dBm, the AP would ignore signals with a strength from -1 dBM to -64 dBm. If the value is set to zero, the feature will automatically determine an appropriate threshold. Shows if Channel Switch Announcements (CSAs) are enabled or disabled. CSAs, as defined by IEEE 802.11h, enable an AP to announce that it is switching to a new channel before it begins transmitting on that channel. This allows clients that support CSA to transition to the new channel with minimal downtime. Number of channel switch announcements that must be sent prior to switching to a new channel. The default CSA count is 4 announcements. Averaging interval for rate limiting mgmt frames from this radio, in seconds. A management frame throttle interval of 0 seconds disables rate limiting. Maximum number of management frames that can come in from this radio in each throttle interval. If enabled, this option disables Adaptive Radio Management (ARM) and Wireless IDS functions and slightly increases packet processing performance. If a radio is configured to operate in Air Monitor mode, then the ARM/WIDS override functions are always enabled, regardless of whether or not this check box is selected. The cell size reduction feature allows you manage dense deployments and to increase overall system performance and capacity by shrinking an AP's receive coverage area, thereby minimizing co-channel interference and optimizing channel reuse. The possible range of values for this feature is 0-55 dB. The default 0 dB reduction allows the radio to retain its current default Rx sensitivity value. 1845 | show rf dot11a-radio-profile Dell Networking W-Series ArubaOS 6.4.x | User Guide
