Automatic Channel Selection; Background Scanning - HP MSM3xx Management And Configuration Manual

Automatic channel selection

When the Automatic channel selection feature is enabled, scanning occurs as follows:
 On the E-MSM430, E-MSM460, E-MSM466: Scanning only occurs when the channel
selection interval expires. This may cause interruptions to voice calls. Therefore,
configuring a short channel selection interval is not recommended.
 On the MSM310, MSM320, MSM335, MSM410, MSM422: Scanning is continuously
performed on all the channels in the currently selected Operating mode, even though
the channel is only re-evaluated each time the channel selection interval expires. (If the
interval is set to Disabled, continuous scanning is not performed.) Continuous scanning
can cause interruptions to voice calls. On dual-radio APs, you can avoid interruptions by
setting one radio to operate in monitor mode. For example, if radio 1 is set to automatic
channel scanning and radio 2 is in monitor mode, scanning occurs on radio 2 and
interruptions on radio 1 do not occur.

Background scanning

(MSM310, MSM320, MSM335, MSM410, MSM422 only)
For any other radio configuration, scanning is controlled by the settings on the Network >
Wireless neighborhood page. To enable scanning, select the Repeat scanning every xx
seconds checkbox and set a value. Scanning is performed for all the channels in the
currently selected radio Operating mode. One channel is scanned during each scan interval.
By default, the scan interval is set to 600 seconds. This is done to minimize the impact on
radio throughput.
Use this method to continuously view APs operating in your area while minimizing the
effect on throughput.
Note
 Scanning is temporarily disabled when a trace is active (Tools > Network trace page).
 To obtain the best possible wireless performance (such as needed for voice applications),
scanning should be disabled.
