Description
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.
l
Level-1: noise immunity only.
l
Level-2: noise and spur immunity. This is the default
l
setting
Level-3: level 2 and weak OFDM immunity.
l
Level-4: level 3 and FIR immunity.
l
Level-5: disable PHY reporting.
l
Displays whether or not the AP has enabled channel switch
announcements (CSAs) for 802.11h.
Number of channel switch announcements that must be
sent before the AP will switch to a new channel.
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.
Maximum number of management frames that can come
from this radio in each throttle interval.
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.
Displays whether or not protection for 802.11b clients is
enabled or disabled.
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.
The upper limit for this parameter varies, depending on the
20/40 MHz mode for a 2.4GHz frequency band radio:
20MHz mode: 54km
l
40MHz mode: 24km
l
Iff you configure a value above the supported maximum, the
maximum supported value will be used instead. Values
below 600m will use default settings.
When this parameter is enabled, it turns an AP in ap-mode
into a hybrid AP. An AP in hybrid AP mode will continue to
serve clients as an access point while it scans and analyzes
spectrum analysis data for a single radio channel.
