Parameter Description
Rogue AP Aware If enabled, Dell APs may change channels to contain off-channel rogue
APs with active clients. This security features allows APs to change
channels even if the Client Aware setting is disabled.
This setting is disabled by default, and should only be enabled in high-
security environments where security requirements are allowed to
consume higher levels of network resources. You may prefer to receive
Rogue AP alerts via SNMP traps or syslog events.
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.
Aggressive Scanning
When the aggressive scanning feature is enabled, an AP radio with no cli-
ents will scan channels every second.
Active Scan If enabled, the 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.
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.
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.
