Radio Settings allow you to configure radios used in your network. Using ADSP, you specify the supported rates and other settings for each radio. If a radio in your network is detected operating outside the set specifications, ADSP issues an alarm.
The settings apply to APs and wireless switches. You may also define a radio as a Sensor.
You may configure Radio Settings at the appliance network level all the way down to the floor network level, but you should always configure Radio Settings at the appliance level. Any network level below the appliance level will inherit the configuration. If you need to have a different configuration below the appliance level, use the Override settings option.
Note
The Override settings option is available when you select (highlight) a network level below the appliance level. Use the Expand
button to
reveal the other levels.
There are three possible radio configurations:
By default, Radio Settings are enabled, and all data rates are selected for both 2.4 and 5ghz radio settings. Use the individual radio tabs to configure each radio.
The configuration fields for each B/G/N Radio and the A/N Radio are:
| Field | Description |

Edit button to set the rates.
 By default, all data rates are selected. For 802.11 a/b/g, select the checkbox for each rate that you want to support. Then, specify if the rate is optional or mandatory. For 802.11n, select the MCSs that you want to support. Also, specify if you want to enable short guard. |

DTIM Period |
Specifies the supported Delivery Traffic Indication Message (DTIM) interval. The default value is 1. |
|
RTS Threshold |
Specifies the supported Request to Send (RTS) threshold. This can be a value between 0 and 2339 bytes. The default value is 2312. |
|
Max Retries |
Specifies the supported number of RTS retries. This can be a value between 1 and 128. The default value is 32. |
