Parameter Description
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.
ARM/WIDS Override
If enabled, 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.
Reduce Cell Size (Rx
Sensitivity)
The cell size reduction feature allows you manage dense deployments and to increase
overall system performance and capacity by shrinking an AP’s receive coverage area,
thereby minimizing co-channel interference and optimizing channel reuse. The possible
range of values for this feature is 0-55 dB. The default 0 dB reduction allows the radio to
retain its current default Rx sensitivity value.
Adaptive Radio
Management (ARM)
Profile
Name of an Adaptive Radio Management profile associated with this 802.11a profile.
High-throughput Radio
Profile
Name of a High Throughput Radio profile associated with this 802.11a profile.
Maximum Distance
Maximum distance between a client and an AP or between a mesh point and a mesh
portal, in meters. This value is used to derive ACK and CTS timeout times. A value of 0
specifies default settings for this parameter, where timeouts are only modified for
outdoor mesh radios which use a distance of 16km..
Spectrum Monitoring
If enabled, the AP operates as a hybrid AP that can simultaneously serve clients and
monitor a single channel for spectrum analysis data.
