Parameter channel-reuse Description Range l num: Entering a channel number disables 40 MHz mode and activates 20 MHz mode for the entered channel. l num+: Entering a channel number with a plus (+) sign selects a primary and secondary channel for 40 MHz and 80 Mhz modes. The number entered becomes the primary channel and the secondary channel is determined by increasing the primary channel number by 4. Example: 157+ represents 157 as the primary channel and 161 as the secondary channel. l num-: Entering a channel number with a minus (-) sign selects a primary and secondary channel for 40 MHz and 80 Mhz modes. The number entered becomes the primary channel and the secondary channel is determined by decreasing the primary channel number by 4. Example: 157represents 157 as the primary channel and 153 as the secondary channel. NOTE: 20 MHz clients are allowed to associate when a primary and secondary channel are configured; however, the client will only use the primary channel. When you enable the channel reuse feature, it can operate in either of the following three modes; static, dynamic or disable. (This feature is disabled by default.) l Static mode: 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 mode: 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. enabled disabled Default enabled Dell Networking W-Series ArubaOS 6.5.x | Reference Guide rf dot11a-radio-profile | 735
