Configuring radio settings for an AP

To configure 2.4 GHz and 5 GHz radio settings for an AP:

1.Select Wireless Configuration > RF > Radio. The Radio details are displayed.

2.Under 2.4.GHz, 5 GHz, or both, configure the following parameters.

Table 16: Radio configuration parameters

Data pane item

Description

LEGACY ONLY

Select Enabled to run the radio in non-802.11n mode. This option is set to

 

Disabled by default.

 

 

802.11d / 802.11h

Select Enabled to allow the radio to advertise its 802.11d (Country Information)

 

and 802.11h (Transmit Power Control) capabilities. This option is set to Disabled

 

by default.

 

 

BEACON

Enter the beacon period for the AP in milliseconds. This indicates how often the

INTERVAL

802.11 beacon management frames are transmitted by the AP. You can specify a

 

value within the range of 60-500. The default value is 100 milliseconds.

 

 

INTERFERENCE

Select to increase the immunity level to improve performance in high-interference

IMMUNITY LEVEL

environments.

 

The default immunity level is 2.

 

• Level 0 — no ANI adaptation.

 

• 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.

 

• 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.

 

• 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.

 

• Level 4 — Level 3 settings, and FIR immunity. At this level, the AP adjusts its

 

sensitivity to in-band power, which can improve performance in environments

 

with high and constant levels of noise interference.

 

• Level 5 — The AP completely disables PHY error reporting, improving

 

performance by eliminating the time the AP spends on PHY processing.

 

NOTE: Increasing the immunity level makes the AP lose a small amount of range.

 

 

CHANNEL

Specify the count to indicate the number of channel switching announcements that

SWITCH

are sent before switching to a new channel. This allows associated clients to

recover gracefully from a channel change.

service to clients, while performing additional function of monitoring RF

interference (from both neighboring APs and non Wi-Fi sources such as,

 

microwaves and cordless phones) on the channel they are currently serving

 

clients.

 

 

3. Reboot the AP after configuring the radio profile settings.

Intrusion detection system

The Intrusion Detection System (IDS) is a feature that monitors the network for the presence of unauthorized APs and clients. It also logs information about the unauthorized APs and clients, and generates reports based on the
