features will automatically select the radio channel with the least amount of interference for each mesh portal, maximizing end user performance. In earlier versions of this software, an AP with a mesh radio received its beacon period, transmission power and 11a/11g portal channel settings from its mesh radio profile. Mesh-access AP portals now inherit these radio settings from their dot11a or dot11g radio profiles. Each ARM-enabled mesh portal monitors defined thresholds for interference, noise, errors, rogue APs and radar settings, then calculates interference and coverage values and selects the best channel for its radio band(s). The mesh portal communicates its channel selection to its mesh points via Channel Switch Announcements (CSAs), and the mesh points will change their channel to match their mesh portal. Although channel settings can still be defined for a mesh point via that mesh point's 802.11a and 802.11g radio profiles, these settings will be overridden by any channel changes from the mesh portal. A mesh point will take the same channel setting as its mesh portal, regardless of its associated clients. If you want to manually assign channels to mesh portals or mesh points, disable the ARM profile associated with the 802.11a or 802.11g radio profile by setting the ARM profile's assignment parameter to disable. The ARM power adjustment feature does not apply to all ARM-enabled Mesh portals. Indoor mesh portals can take advantage of this feature to adjust power settings according to their ARM profiles, but outdoor mesh portals will continue to run at configured power level to maximize their range. NOTE: Do not delete or modify mesh cluster profiles once you use them to provision mesh nodes. You can recover the mesh point if the original cluster profile is still available. Dell PowerConnect W recommends creating a new mesh cluster profile if needed. Perform these steps to create or edit an adaptive radio management (ARM) profile. 1. Select Profiles > RF > 802.11a/g Radio > ARM in the Dell PowerConnect W Navigation pane. 2. Select the Add button to create a new ARM profile, or click the pencil icon to edit an existing profile. The Details page appears. Complete the settings as described in Table 43: Table 43 Profiles > RF > 802.11a/g Radio > ARM Profile Settings Field Default Description General Settings Folder Top Name Other Settings Assignment Blank singleband Allowed Bands for a-only 40MHz Channels Set the folder with which the profile is associated. The drop-down menu displays all folders available for association with the profile. Enter the name of the profile. Activates one of four ARM channel/power assignment modes.  disable-Disables ARM calibration and reverts APs back to default channel and power settings specified by the AP's radio profile  maintain-APs maintain their current channel and power settings. This setting can be used to maintain AP channel and power levels after ARM has initially selected the best settings.  multi-band-For single-radio APs, this value computes ARM assignments for both 5 GHZ (802.11a) and 2.4 GHZ (802.11b/g) frequency bands.  single-band-For dual-radio APs, this value enables APs to change transmit power and channels within their same frequency band, and to adapt to changing channel conditions. Set the 802.11 radio bands to be supported by this ARM profile. The drop-down menu supports the following options:  a-only-802.11a radio bands  g-only-802.11g radio bands  all-both 802.11a and g bands Dell PowerConnect W AirWave 7.2 | Configuration Guide Dell PowerConnect W Configuration Reference | 103
