Concept Guide

Parameter Description Range Default
csa
Channel Switch Announcement (CSA), as
defined by IEEE 802.11h, allows an AP to
announce that it is switching to a new
channel before it begins transmitting on
that channel.
Clients must support CSA in order to track
the channel change without experiencing
disruption.
— disabled
csa-count
Number of CSA announcements that are
sent before the AP begins transmitting on
the new channel.
1-16 4
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 this parameter with
caution. Enabling this parameter
effectively disables ARM and WIDS.
— OFF
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 761.
— “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.
Level-0 -
Level-15
Level-2
