Configure Neighborhood Analysis

Using background scanning, an AP divides a full background channel scan into several shorter partial scans so they do not interfere with the beacons sent by the AP. The scan takes less time than the beacon interval (100 TU by default), and is spread out over a number of beacon intervals until the AP scans all available channels. Full scans occur at admin-defined intervals, with a default of 10 minutes.

Use this task to configure neighborhood analysis (background scanning) settings.

Note

Note

Extreme Networks provides defaults for each item in this section. The following steps are optional.
  1. Go to Configure > Common Objects > Policy > Radio Profiles.
  2. and then select Edit, or select Add.
  3. In the Neighborhood Analysis section, toggle Background Scan ON or OFF.

    Background scanning is necessary for WIPS and Layer 3 roaming to function.

  4. Set the interval between background scans of all radio channels.

    Perform Background Scan Every: The range is 1 to 1440 minutes (24 hours).

  5. For Skip Background Scan When, specify when to skip background scans:
    • Select Clients are connected to enable an AP with connected clients to scan channels.
    • Select Connected clients are in power save mode to enable an AP to scan channels when connected clients are in power save mode.
    • Select Network traffic with voice priority is detected to prevent an AP from performing a background scan when voice traffic is detected.

    Voice traffic takes priority and is the least forgiving of slow or degraded connections.

  6. Select SAVE RADIO PROFILE.
