Spectrum Load
Balancing
No The Spectrum Load Balancing feature helps optimize network resources by balancing
clients across channels, regardless of whether the AP or the controller is responding to the
wireless clients' probe requests.
If enabled, the controller compares whether or not an AP has more clients than its
neighboring APs on other channels. If an AP’s client load is at or over a predetermined
threshold as compared to its immediate neighbors, or if a neighboring Dell AP on another
channel does not have any clients, load balancing will be enabled on that AP. This feature
is disabled by default.
Spectrum Load
Balancing Mode
Channel 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
Spectrum Load
Balancing Domain
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.

30 Specify how often spectrum load balancing calculations are made (in seconds). The range
is 1-2147483647 seconds.
RX Sensitivity
Tuning Based
Channel Reuse
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 Dell PowerConnect W-Series ArubaOS 6.0 User Guide at
support.dell.com/manuals.
RX Sensitivity
Threshold
(-dBm)
0 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.
