Parameter Description
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
SLB Mode allows control over how to balance clients. Channel-based load-balancing
balances clients across channels. Radio-based load-balancing distributes clients
across radios on the same band, independent of channels.
Spectrum load balancing
mode update interval
This parameter specifies how often spectrum load balancing calculations are made (in
seconds). The default value is 30 seconds.
Spectrum load balancing
threshold If the spectrum load balancing feature is enabled, this parameter controls the
percentage difference between number of clients on a channel channel that triggers
load balancing. The default value is 20%, meaning that spectrum load balancing is
activated when there are 20% more clients on one channel than on another channel
used by the AP radio.
Advertised Regulatory
Max EIRP
Shows if the radio is configured to work around a known issue on Cisco 7921G
telephones by capping for a radio’s maximum equivalent isotropic radiated power
(EIRP). When you enable this parameter, even if the regulatory approved maximum for a
given channel is higher than this EIRP cap, the AP radio using this profile will advertise
only this capped maximum EIRP in its radio beacons.
The supported value is1–31 dBm.
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.
l
If spectrum load balancing is enabled in a 802.11g radio profile but the spectrum
load balancing domain is
not defined, ArubaOS uses the ARM feature to calculate
RF neighborhoods.
l
If spectrum load balancing is enabled in a 802.11g radio profile and a spectrum load
balancing domain
isalso 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.
RX Sensitivity Tuning
Based Channel Reuse
Shows if the channel reuse feature’s current operating mode, static, dynamic or
disable.
l
Static: 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: 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.
l
Disable: This mode does not support the tuning of the CCA Detect Threshold.
RX Sensitivity
Threshold
If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this
parameter manually sets the AP’s Rx sensitivity threshold (-dBm). The AP will filter out
and ignore weak signals that are below the channel threshold signal strength. For
example, if the RX sensitivity threshold was set to -65 dBm, the AP would ignore signals
with a strength from -1 dBM to -64 dBm. If the value is set to zero, the feature will
automatically determine an appropriate threshold.
Non 802.11 Interference
Show the current value for 802.11 Interference Immunity on the 2.4 Ghz band.
