Parameter
Description
The default immunity level is 2.
l
Level 0
—no ANI adaptation.
l
Level 1
—Noise immunity only. This level enables power-based packet detection by
controlling the amount of power increase that makes a radio aware that it has received a
packet.
l
Level 2
—Noise and spur immunity. This level also controls the detection of OFDM
packets, and is the default setting for the Noise Immunity feature.
l
Level 3
—Level 2 settings and weak OFDM immunity. This level minimizes false detects
on the radio due to interference, but may also reduce radio sensitivity. This level is
recommended for environments with a high-level of interference related to 2.4 GHz
appliances such as cordless phones.
l
Level 4
—Level 3 settings, and FIR immunity. At this level, the IAP adjusts its sensitivity to
in-band power, which can improve performance in environments with high and constant
levels of noise interference.
l
Level 5
—The IAP completely disables PHY error reporting, improving performance by
eliminating the time the IAP would spend on PHY processing.
NOTE:
Increasing the immunity level makes the IAP to lose a small amount of range.
Channel switch
announcement
count.
Specify the count to indicate the number of channel switching announcements that must be
sent before switching to a new channel. This allows associated clients to recover gracefully
from a channel change.
Background
spectrum
monitoring
Select
Enabled
to allow the IAPs in access mode to continue with normal access service to
clients, while performing additional function of monitoring RF interference (from both
neighboring IAPs and non Wi-Fi sources such as, microwaves and cordless phones) on the
channel they are currently serving clients.
Customize
ARM power range
Select the check box and select a minimum (
Min Power
) and maximum (
Max Power
) power
range value for the 2.4 GHz and 5 GHz band frequencies. The default value is 3 dBm. Unlike
the configuration in the ARM profile, the transmit power of all radios in the Radio profile do
not share the same configuration.
Very high
throughput
Ensure that this check box is selected to enable very high throughput (VHT) on 802.11ac
devices with 5 GHz radio. If VHT is enabled for the 5 GHz radio profile on an IAP, it is
automatically enabled for all SSIDs configured on an IAP. By default, VHT is enabled on all
SSIDs.
If you want the 802.11ac IAPs to function as 802.11n IAPs, clear the check box to disable VHT
on these devices.
