Table 43 Profiles > RF > 802.11a/g Radio > ARM Profile Settings (Continued) Field Default Description Client Aware Yes If the Client Aware option is enabled, the AP does not change channels if there is active client traffic on that AP. If Client Aware is disabled, the AP may change to a more optimal channel, but this change may also disrupt current client traffic. Max Tx Power 30 (dBm) Set the highest transmit power levels for the AP, from 0-30 dBm in 3 dBm increments. Higher power level settings may be constrained by local regulatory requirements and AP capabilities. In the event that an AP is configured for a Max Tx Power setting it cannot support, this value will be reduced to the highest supported power setting. NOTE: Power settings will not change if the Assignment option is set to disabled or maintain. Min Tx Power (dBm) 9 Multi Band Scan Yes Set the lowest transmit power levels for the AP, from 0-30 dBm, in 3 dBm increments. Note that power settings will not change if the Assignment option is set to disabled or maintain. NOTE: Consider configuring a Min Tx Power setting higher than the default value if most of your APs are placed on the ceiling. APs on a ceiling often have good line of sight between them, which will cause ARM to decrease their power to prevent interference. However, if the wireless clients down on the floor do not have such a clear line back to the AP, you could end up with coverage gaps. If enabled, single radio channel APs scans for rogue APs across multiple channels. This option requires that Scanning is also enabled. The Multi Band Scan option does not apply to APs that have two radios, such as an Dell PowerConnect W AP-65??? or AP-70???, as these devices already scan across multiple channels. If one of these dual-radio devices are assigned an ARM profile with Multi Band enabled, that device will ignore this setting. Rogue AP Aware No If you have enabled both the Scanning and Rogue AP options, Dell PowerConnect W APs may change channels to contain off-channel rogue APs with active clients. This security feature allows APs to change channels even if the Client Aware setting is disabled. This setting is disabled by default, and should only be enabled in high-security environments where security requirements are allowed to consume higher levels of network resources. You may prefer to receive Rogue AP alerts via SNMP traps or syslog events. Scan Interval (sec) 10 If Scanning is enabled, the Scan Interval defines how often the AP will leave its current channel to scan other channels in the band. Off-channel scanning can impact client performance. Typically, the shorter the scan interval, the higher the impact on performance. If you are deploying a large number of new APs on the network, you may want to lower the Scan Interval to help those APs find their optimal settings more quickly. Raise the Scan Interval back to its default setting after the APs are functioning as desired. The supported range for this setting is 0 to 2,147,483,647 seconds. Active Scan No When the Active Scan checkbox is selected, an AP initiates active scanning via probe request. This option elicits more information from nearby APs, but also creates additional management traffic on the network. Active Scan is disabled by default, and should not be enabled except under the direct supervision of AirWave or Dell PowerConnect W Support. Scanning Scan Time Yes The Scanning field enables or disables AP scanning across multiple channels. Disabling this option also disables the following scanning features:  Multi Band Scan  Rogue AP Aware  VoIP Aware Scan  Power Save Aware Scan Do not disable Scanning unless you want to disable ARM and manually configure AP channel and transmission power. 110 msec The amount of time, in milliseconds, an AP will drift out of the current channel to scan another channel. The supported range for this setting is 50 to 2,147,483,647 milliseconds. Dell PowerConnect W recommends a scan time between 50 to 200 msec. 104 | Dell PowerConnect W Configuration Reference Dell PowerConnect W AirWave 7.2 | Configuration Guide
