Setting Description
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:
l Classify the frame as video traffic via a session ACL.
l 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.
Scan Mode By default, 802.11n-capable APs scan channels within all regulatory domains. To limit the AP
scans to just the regulatory domain for that AP, click the Scan Mode drop-down list and
select reg-domain.
NOTE: This setting does not apply to APs that do not support 802.11n; these APs will scan
their regulatory domain only.
Client Match Select this checkbox to enable the client match feature, which monitors clients' RF neigh-
borhood to provide ongoing client bandsteering and load balancing, and enhanced AP reas-
signment for roaming mobile clients. For complete information on this feature, see Client
Match on page 434.
Advanced Configuration Settings
Assignment Activates one of four ARM channel/power assignment modes:
l disable: Disables ARM calibration and reverts APs back to default channel and power
settings specified by the AP’s radio profile.
l maintain: APs maintain their current channel and power settings. This setting can be
used to maintain AP channel and power levels after ARM has initially selected the best
settings.
l multi-band: For single-radio APs, this value computes ARM assignments for both 5 GHZ
(802.11a) and 2.4 GHZ (802.11b/g) frequency bands.
l single-band: For dual-radio APs, this value enables APs to change transmit power and
channels within their same frequency band, and to adapt to changing channel conditions.
Default: single-band
Allowed
bands for
40MHz
channels
The specified setting allows ARM to determine if 40 MHz mode of operation is allowed on
the 5 GHz or 2.4 GHz frequency band only, on both frequency bands, or on neither
frequency band.
Client Aware If the Client Aware option is enabled, the AP does not change channels if there is an active
client associated to that AP. (Activity is defined by the sta-inactivity-time parameter in the
IDS general profile. By default, a client is considered active if it has sent or received traffic
within the last 60 seconds.)
If you disable Client Aware , the AP may change to a more optimal channel, but this change
may also disrupt current client traffic.
Default: enabled
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.
Default: 127 dBm
NOTE: Power settings will not change if the Assignment option is set to disabled or
maintain.
