Configuring WIDS Device Detection

Configuring WIDS Device Detection

Context

Rogue devices on WLANs create security risks. To identify these devices, the administrator can enable the device detection function so that the RU can periodically report the detected device information to the central AP, and the central AP can identify rogue devices.

The RU periodically reports the detected wireless device information to the central AP, including the incremental and modified device information in detection intervals. Information may be lost on WLANs, resulting in inconsistent device information on the central AP and RU. To address this problem, the RU periodically reports all the detected device information. Then the central AP and RU periodically synchronize wireless device information.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    wlan

    The WLAN view is displayed.

  3. Enable device detection on radios in an AP group or on a specified AP radio.

    You can enable device detection in the AP group radio view or AP 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.

    • Enable device detection on 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 wids device detect enable command to enable device detection.

        By default, device detection is disabled on radios in an AP group.

      4. Run the quit command to return to the AP group view.

    • Enable device detection on an 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 wids device detect enable command to enable device detection.

        By default, device detection is disabled on an AP radio.

      4. Run the quit command to return to the AP view.

  4. (Optional) Set the intervals at which an RU reports the incremental detected wireless device information
    1. Run the quit command to return to the WLAN view.
    2. Run the wids-profile name profile-name command to enter the WIDS profile view.
    3. Run the device report-interval interval command to set the interval at which an RU reports the incremental detected wireless device information.

      By default, an RU reports incremental wireless device information to a central AP at an interval of 300 seconds.
