Description
Disables Adaptive Radio Management (ARM) and
Wireless IDS functions. These can be disabled if a
small increase in packet processing performance
is desired. If a radio is configured to operate in Air
Monitor mode, then these functions are always
enabled irrespective of this option. CAUTION: Use
carefully, since this effectively disables ARM and
WIDS
Enable advertisement of 802.11d (Country
Information) and 802.11h (TPC or Transmit Power
Control) capabilities This parameter is disabled by
default.
Enables high-throughput (802.11n) features on a
radio using the 5 GHz frequency band.
Name of high-throughput radio profile to use for
configuring high-throughput support on the 5 GHz
frequency band. See "rf ht-radio-profile" on page
538.
Set a value for 802.11 Interference Immunity. 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
l
default setting
Level-3: level 2 and weak OFDM immunity.
l
Level-4: level 3 and FIR immunity.
l
Level-5: disable PHY reporting.
l
NOTE: Do not raise the noise immunity feature's
"channel-reuse-threshold" on
default setting if the
page 521 feature is also enabled. A level-3 to
level-5 Noise Immunity setting is not compatible
with the Channel Reuse feature.
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 5 GHz
frequency band radio:
20MHz mode: 58km
l
40MHz mode: 27km
