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.
Non 802.11 Interference
Immunity
Show the current value for 802.11 Interference Immunity on the 2.4 Ghz
band.
The default setting for this parameter is level 2. When performance drops
due to interference from non-802.11 interferers (such as DECT or Bluetooth
devices), the level can be increased up to level 5 for improved performance.
However, increasing the level makes the AP slightly “deaf” to its
surroundings, causing the AP to lose a small amount of range.
The levels for this parameter are:
l Level-0: no ANI adaptation.
l Level-1: noise immunity only.
l Level-2: noise and spur immunity.
l Level-3: level 2 and weak OFDM immunity.
l Level-4: level 3 and FIR immunity.
l Level-5: disable PHY reporting.
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.
Protection for 802.11b
Clients
Shows if the profile has enabled or disabled protection for 802.11b clients.

High-throughput Radio
Profile
Name of a High Throughput Radio profile associated with this 802.11a
profile.
