Setting Description Defaults
Off-channel scanning can impact client
performance. Typically, the shorter the scan
interval, the higher the impact on performance. If
you are deploying a large number of new APs on
the network, you may want to lower the Scan
Interval to help those APs find their optimal settings
more quickly. Raise the Scan Interval back to its
default setting after the APs are functioning as
desired.
Range: 0–2,147,483,647 seconds.
Active Scan When you enable Active Scan, an AP initiates
active scanning via probe request. This option
elicits more information from nearby APs, but also
creates additional management traffic on the
network. Active Scan is disabled by default, and
should not be enabled except under the direct
supervision of Dell Support.
Disabled
ARM Over the Air
Updates
The ARM Over the Air Updates option allows an
AP to get information about its RFenvironment
from its neighbors, even the AP cannot scan. If this
feature is enabled, when an AP on the network
scans a foreign (non-home) channel, it sends other
APs an Over-the-Air (OTA) update in an 802.11
management frame that contains information
about the scanning AP's home channel, the current
transmission EIRP value of its home channel, and
one-hop neighbors seen by that AP.
Default: enabled
Enabled
Scanning The Scanning checkbox enables or disables AP
scanning across multiple channels. Disabling this
option also disables the following scanning
features:
l Multi Band Scan
l Rogue AP Aware
l Voip Aware Scan
l Power Save Scan
Do not disable Scanning unless you want to disable
ARM and manually configure AP channel and
transmission power.
Enabled
Multi Band Scan If enabled, single radio channel APs scans for
rogue APs across multiple channels. This option
requires that Scanning is also enabled.
Disabled
