Rx sensitivity tuning
based channel reuse
The channel reuse feature can operate in either of the following three modes; static,
dynamic or disable. (This feature is disabled by default.)
 Static mode: 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.
 Dynamic mode: 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.
 Disable mode: This mode does not support the tuning of the CCA Detect Threshold.
Rx sensitivity threshold RX Sensitivity Tuning Based Channel Reuse Threshold, in -dBm.
If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this
parameter manually sets the AP’s Rx sensitivity threshold (in -dBm). The AP will filter out
and ignore weak signals that are below the channel threshold signal strength.
If the value is set to zero, the feature will automatically determine an appropriate
threshold
Non 802.11a interference
Immunity
The value for 802.11 Interference Immunity. This parameter sets the 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:
 Level-0: no ANI adaptation.
 Level-1: noise immunity only.
 Level-2: noise and spur immunity. This is the default setting
 Level-3: level 2 and weak OFDM immunity.
 Level-4: level 3 and FIR immunity.
 Level-5: disable PHY reporting.
Enable CSA Displays whether or not the AP has enabled channel switch announcements (CSAs) for
802.11h.
CSA Count Number of channel switch announcements that must be sent before the AP will switch to
a new channel.
Management Frame Throttle
interval
Average interval that rate limiting management frames are sent from this radio, in
seconds. If this column displays a zero (0) rate limiting is disabled for this AP.
Management Frame Throttle
Limit
Maximum number of management frames that can come from this radio in each throttle
interval.
ARM/WIDS Override Shows if Adaptive Radio Management (ARM) and Wireless IDS functions are enabled or
disabled. If a radio is configured to operate in Air Monitor mode, then these functions are
always enabled, regardless of this option.
Protection for 802.11b
Clients
Displays whether or not protection for 802.11b clients is enabled or disabled.
