Setting Description
Max Tx EIRP Maximum effective isotropic radiated power (EIRP) from 3 to 33 dBm in 3 dBm increments.
You may also specify a special value of 127 dBm for regulatory maximum. Higher power
level settings may be constrained by local regulatory requirements and AP capabilities. In
the event that an AP is configured for a Max Tx EIRP setting it cannot support, this value will
be reduced to the highest supported power setting. The default value for this parameter is
127 dBm.
NOTE: Power settings will not change if the Assignment option is set to disabled or
maintain.
Min Tx EIRP Minimum effective isotropic radiated power (EIRP) from 3 to 33 dBm in 3 dBm increments.
You may also specify a special value of 127 dBm for regulatory maximum to disable power
adjustments for environments such as outdoor mesh links. Note that power settings will not
change if the Assignment option is set to disabled or maintain. Higher power level
settings may be constrained by local regulatory requirements and AP capabilities. In the
event that an AP is configured for a Min Tx EIRP setting it cannot support, this value will be
reduced to the highest supported power setting. The default value for this parameter is 9
dBm.
Consider configuring a Min Tx Power setting higher than the default value if most of your
APs are placed on the ceiling. APs on a ceiling often have good line of sight between them,
which will cause ARM to decrease their power to prevent interference. However, if the
wireless clients down on the floor do not have such a clear line back to the AP, you could end
up with coverage gaps.
Client Match The client match feature helps optimize network resources by balancing clients across
channels, regardless of whether the AP or the controller is responding to the wireless
clients' probe requests.
If enabled, the controller compares whether an AP has more clients than its neighboring APs
on other channels. If an AP’s client load is at or over a predetermined threshold as
compared to its immediate neighbors, or if a neighboring Dell AP on another channel does
not have any clients, load balancing will be enabled on that AP. This feature is enabled by
default. For details, see Client Match on page 434.
Scanning The Scanning checkbox enables or disables AP scanning across multiple channels. This
checkbox is selected by default. Do not disable scanning unless you want to disable ARM and
manually configure AP channel and transmission power. 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
Multi Band
Scan
If enabled, single radio channel APs scans for rogue APs across multiple channels. This
option requires that Scanning is also enabled.
(The Multi Band Scan option does not apply to APs that have two radios, as these devices
already scan across multiple channels. If one of these dual-radio devices are assigned an
ARM profile with Multi Band enabled, that device will ignore this setting.)
Default: disabled
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 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.
Default: disabled
Power Save
Aware Scan
If enabled, the AP will not scan a different channel if it has one or more clients that is in
power save mode.
Default: disabled
