Parameter Description
Scanning Shows if the AP has enabled or disabled AP scanning of other channels.
Scan Time The amount of time, in milliseconds, an AP will drift out of the current
channel to scan another channel.
VoIP Aware Scan Shows if Dell’s VoIP Call Admission Control (CAC) prevents any single AP
from becoming congested with voice calls. If CAC is enabled, you should
also enable VoIP Aware Scan 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.
Power Save Aware Scan When enabled, the AP will not scan if Power Save is active.
Video Aware Scan If Video Aware Scan is enabled in the ARM profile, the AP will not attempt to
scan a different channel if one of its clients has an active video session.
Ideal Coverage Index The coverage that the AP should try to achieve on its channel. The denser
the AP deployment, the lower this value should be.
Acceptable Coverage Index The minimal coverage that the AP should try to achieve on its channel. The
denser the AP deployment, the lower this value should be.
Free Channel Index The difference in the interference index between the new channel and
current channel must exceed this value for the AP to move to a new
channel. The higher this value, the lower the chance an AP will move to the
new channel.
Interfering AP Weight Weight of interfering APs in interference index calculation.
Backoff Time Time, in seconds, an AP backs off after requesting a new channel or power
level.
Error Rate Threshold The percentage of errors in the channel that triggers a channel change.
Error Rate Wait Time Time, in seconds, that the error rate has to maintain or surpass the error
rate threshold before it triggers a channel change.
Channel Quality Aware Arm Shows if ARM changes are based upon an internally calculated channel
quality metric. When this feature is disabled, ARM initiates channel
changes based on thresholds defined in this profile, and chooses the
channel based on the calculated interference index value. Default:
Disabled.
Channel Quality Threshold Displays the channel quality percentage below which ARM initiates a
channel change.
Channel Quality Wait Time If channel quality is below the specified channel quality threshold for this
wait time period, ARM initiates a channel change.
