Usage Guidelines
Adaptive Radio Management (ARM) is a radio frequency (RF) resource allocation algorithm that allows each AP
to determine the optimum channel selection and transmit power setting to minimize interference and maximize
coverage and throughput. This command configures an ARM profile that you apply to a radio profile for the 5
GHz or 2.4 GHz frequency band (see “rf dot11a-radio-profile” on page 397 or “rf dot11g-radio-profile” on
page 403).
scan-interval If Scanning is enabled, the Scan Interval defines how often
the AP will leave its current channel to scan other channels
in the band.
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.

scan-mode Select the scan mode for the AP.
z all-reg-domain: The AP scans channels within all
regulatory domains. This is the default setting.
z reg-domain:Limit the AP scans to just the regulatory
domain for that AP.

scan-time The amount of time, in milliseconds, an AP will drift out of
the current channel to scan another channel.

scanning The Scanning checkbox enables or disables AP scanning
across multiple channels. Disabling this option also
disables the following scanning features:
z Multi Band Scan
z Rogue AP Aware
z Voip Aware Scan
z Power Save Scan
Do not disable Scanning unless you want to disable ARM
and manually configure AP channel and transmission
power.
— enabled
video-aware-scan As long as there is at least one video frame every 100 mSec
the AP will reject an ARM scanning request. Note that for
each radio interface, video frames must be defined in one
of two ways:
z Classify the frame as video traffic via a session ACL.
z Enable WMM on the WLAN’s SSID profile and define a
specific DSCP value as a video stream. Next, create a
session ACL to tag the video traffic with the that DSCP
value.
— enabled
voip-aware-scan Dell’s VoIP Call Admission Control (CAC) prevents any single
AP from becoming congested with voice calls. When you
enable CAC, you should also enable voip-aware-scan
parameter in the ARM profile, so the AP will not attempt to
scan a different channel if one of its clients has an active
VoIP call. This option requires that scanning is also
enabled.
