Release Notes

Parameter Description
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.
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 optim-
izing 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 sens-
itivity 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.
