Parameter Description 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 Non 802.11 Interference Immunity Enable CSA CSA Count 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. Show the current value for 802.11 Interference Immunity on the 2.4 Ghz band. The default setting for this parameter is level 2. When performance drops due to interference from non-802.11 interferers (such as DECT or Bluetooth devices), the level can be increased up to level 5 for improved performance. However, increasing the level makes the AP slightly "deaf" to its surroundings, causing the AP to lose a small amount of range. The levels for this parameter are: l Level-0: no ANI adaptation. l Level-1: noise immunity only. l Level-2: noise and spur immunity. l Level-3: level 2 and weak OFDM immunity. l Level-4: level 3 and FIR immunity. l Level-5: disable PHY reporting. 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. 1856| show rf dot11g-radio-profile Dell Networking W-Series ArubaOS 6.5.x | Reference Guide
