Table 41 Profiles > RF > 802.11a/g Profile Settings (Continued) Field Default Description Spectrum Load Balancing Mode channel Spectrum Load Balancing Domain SLB Mode allows control over how to balance clients. Select one of the following options  channel: Channel-based load-balancing balances clients across channels. This is the default load-balancing mode  radio: Radio-based load-balancing balances clients across APs Define a spectrum load balancing domain to manually create RF neighborhoods. Use this option to create RF neighborhood information for networks that have disabled Adaptive Radio Management (ARM) scanning and channel assignment.  If spectrum load balancing is enabled in a 802.11a radio profile but the spectrum load balancing domain is not defined, ArubaOS uses the ARM feature to calculate RF neighborhoods.  If spectrum load balancing is enabled in a 802.11a radio profile and a spectrum load balancing domain is also defined, AP radios belonging to the same spectrum load balancing domain will be considered part of the same RF neighborhood for load balancing, and will not recognize RF neighborhoods defined by the ARM feature. Spectrum Load 30 Balancing Update Interval Specify how often spectrum load balancing calculations are made (in seconds). The range is 1-2147483647 seconds. RX Sensitivity Tuning Based Channel Reuse RX Sensitivity 0 Threshold (-dBm) Enable CSA No In some dense deployments, it is possible for APs to hear other APs on the same channel. This creates co-channel interference and reduces the overall utilization of the channel in a given area. Channel reuse enables dynamic control over the receive (Rx) sensitivity in order to improve spatial reuse of the channel. This feature is disabled by default. To enable this feature, click the drop-down list and select either static or dynamic. To disable this feature, click the drop-down list and select disable. For details on each of these modes, see the "RX Sensitivity Tuning Based Channel Reuse" topic in the ArubaOS 6.0 User Guide. RX sensitivity tuning based channel reuse threshold, in - dBm. If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this parameter manually sets the AP's Rx sensitivity threshold (in -dBm). The AP will filter out and ignore weak signals that are below the channel threshold signal strength. If the value for this parameter is set to zero, the feature will automatically determine an appropriate threshold. Enable or disable Channel Switch Announcements (CSAs), as defined by IEEE 802.11h. This setting enables 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. CSA Count 4 (1-16) Management Frame 1 Throttle Interval Set the number of channel switch announcements that must be sent prior to switching to a new channel. Set the averaging interval for rate limiting management frames from this radio, in seconds. A management frame throttle interval of 0 seconds disables rate limiting. Management Frame 20 Throttle Limit ARM/WIDS No Override Set the maximum number of management frames that can come in from this radio in each throttle interval. If selected, 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.
