Parameter Description
l If spectrum load balancing is enabled in a 802.11a 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.
Enable CSA Shows if Channel Switch Announcements (CSAs) are enabled or disabled.
CSAs, as defined by IEEE 802.11h, enable 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 Number of channel switch announcements that must be sent prior to
switching to a new channel. The default CSA count is 4 announcements.
Management Frame
Throttle Interval
Averaging interval for rate limiting mgmt frames from this radio, in
seconds. A management frame throttle interval of 0 seconds disables rate
limiting.
Management Frame
Throttle Limit
Maximum number of management frames that can come in from this
radio in each throttle interval.
