Radio Settings allow you to specify the radio settings used in your network. Using AirDefense, you specify the supported rates and other settings for each radio. If a radio in your network is detected operating outside the set specifications, AirDefense issues an alarm.
The settings apply to APs and wireless switches. You may also define a radio as a sensor. 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 |
|---|---|
Function |
Defines the radio as a sensor or an infrastructure device (AP or wireless switch). You can also disable the radio. |
Data Rates |
Sets the data rates for the radios. You can set rates for 802.11 a/b/g as a group or 802.11 n. |
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. |
Preamble |
Specifies that the preamble is short or long. |
Beacon Period |
Specifies the supported beacon interval (period) in kilo-microseconds. The default value is 0. |
Max Data Retries |
Specifies how often to resend packets. This can be a value between 1 and 128. The default value is 32. |
Fragmentation Threshold |
Specifies the level that traffic fragments. This can be a value between 256 and 2346 bytes. The default is 2346. |
Ethernet Encapsulation |
Specifies that the Ethernet encapsulation is 802.1h or RFC1042. |
You may also specify the frame aggregation as A-MSDU, A-MPDU, or both.
