Parameter Description Range Default
disable-arm-wids-function 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 1-16 4
dot11h Enable advertisement of 802.11d (Country
Information) and 802.11h (TPC or Transmit Power
Control) capabilities This parameter is disabled by
default. — disabled
high-throughput-enable Enables high-throughput (802.11n) features on a
radio using the 5 GHz frequency band. — enabled
ht-radio-profile
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 .
— “default-a”
interference-immunity
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:
l
Level-0: no ANI adaptation.
l
Level-1: noise immunity only.
l
Level-2: noise and spur immunity. This is the
default setting
l
Level-3: level 2 and weak OFDM immunity.
l
Level-4: level 3 and FIR immunity.
l
Level-5: disable PHY reporting.
NOTE: Do not raise the noise immunity feature’s
default setting if the
"channel-reuse-threshold" on
page 521 feature is also enabled. A level-3 to
level-5 Noise Immunity setting is not compatible
with the Channel Reuse feature.
Level-0 -
Level-15 Level-2
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.
The upper limit for this parameter varies,
depending on the 20/40 MHz mode for a 5 GHz
frequency band radio:
l
20MHz mode: 58km
l
40MHz mode: 27km
Note that if you configure a value above the
0-57km (40MHz
mode)
0-27km
(20MHz mode)
0 meters
