Using background scanning, an AP divides a full background channel scan into several
shorter partial scans so they do not interfere with the AP's own beacons. 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
Extreme Networks provides
defaults for each item in this section. The following steps are optional.
-
Toggle Background
Scan on or off.
Background scanning is necessary for WIPS and Layer 3 roaming to
function.
-
Set the interval between
background scans of all radio channels.
The range is 1 to 1440 minutes (24 hours).
-
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.
