Configuring the Radio Working Mode

Context

Before configuring rogue device detection and containment, you need to configure the radio working mode to determine whether a radio only transmits common WLAN services or both transmits common WLAN services and performs the monitoring function.

An AP can work in two modes:

normal: indicates the normal mode.
- If air scan functions (such as WIDS, spectrum analysis, and terminal location) are disabled on a radio, the radio is used to transmit common WLAN services.
- If air scan functions (such as WIDS, spectrum analysis, and terminal location) are enabled on a radio, the radio transmits common WLAN services and also provides the monitoring function. A transient increase in the WLAN service latency may occur, which does not affect network access. However, if any latency-sensitive service (such as videoconferencing) is running, it is recommended that a separate radio be used for air scan.
monitor: indicates the monitor mode.
In this mode, the radio can only transmit WLAN services scanned by the air interface but cannot transmit common WLAN services.
In monitor mode, some APs support the following functions:
- dual-band-scan: indicates inter-band scanning. In this mode, the radio can perform scanning at both the 2.4 GHz and 5 GHz bands.
- proxy-scan: indicates proxy scanning. In this mode, the radio is dedicated to all air interface scanning functions on behalf of service radios, ensuring that services on the service radios are not affected.

Procedure

Run system-view
The system view is displayed.
Run wlan
The WLAN view is displayed.
Set the working mode for radios in an AP group or for a specified radio.
You can set the radio working mode in the AP radio view or AP group radio view. The configuration in the AP group radio view takes effect on all AP radios in an AP group and that in the AP radio view takes effect only on a specified AP radio. The configuration in the AP radio view has a higher priority than that in the AP group radio view.
- Set the working mode for all radios in an AP group.
  1. Run the ap-group name group-name command to enter the AP group view.
  2. Run the radio radio-id command to enter the radio view.
  3. Run the work-mode { normal | monitor [ [ proxy-scan ] dual-band-scan enable ] } command to set the working mode for radios in an AP group.
    
    By default, radios in an AP group work in normal mode.
  4. Run the quit command to return to the AP group view.
- Set the working mode for a specified AP radio.
  1. Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
  2. Run the radio radio-id command to enter the radio view.
  3. Run the work-mode { normal | monitor [ [ proxy-scan ] dual-band-scan enable ] } command to set the working mode for a specified AP radio.
    
    By default, an AP radio works in normal mode.
  4. Run the quit command to return to the AP view.
