RF Management Profiles
The profiles configure radio tuning and calibration, AP load balancing, and RSSI metrics.
l 802.11a radio profile: defines AP radio settings for the 5 GHz frequency band, including the Adaptive
Radio Management (ARM) profile and the high-throughput (802.11n) radio profile. For additional
information on configuring this profile, see 802.11a and 802.11g RF Management Profiles on page 593.
l 802.11g radio profile: defines AP radio settings for the 2.4 GHz frequency band, including the Adaptive
Radio Management (ARM) profile and the high-throughput (802.11n) radio profile. Each 802.11a and
802.11b radio profile includes a reference to an Adaptive Radio Management (ARM) profile.
If you want the ARM feature to dynamically select the best channel and transmission power for the radio,
verify that the 802.11a/802.11g radio profile references an active and enabled ARM profile. If you want to
manually select a channel for each AP group, create separate 802.11a and 802.11g profiles for each AP
group and assign a different transmission channel for each profile. For additional information on
configuring this profile, see 802.11a and 802.11g RF Management Profiles on page 593.
l ARM profile: defines the Adaptive Radio Management (ARM) settings for scanning, acceptable coverage
levels, transmission power and noise thresholds. In most network environments, ARM does not need any
adjustments from its factory-configured settings. However, if you are using VoIP or have unusually high
security requirements you may want to manually adjust the ARM thresholds. For complete details on
Adaptive Radio Management, refer to Adaptive Radio Management on page 510.
l High-throughput radio profile: manages high-throughput (802.11n) radio settings for 802.11n-capable
APs. A high-throughput profile determines 40 Mhz tolerance settings, and controls whether or not the APs
using this profile will advertise intolerance of 40 MHz operation. (This option is disabled by default, allowing
40 MHz operation.) For additional information on configuring this profile, see High-Throughput Virtual APs
on page 502.
l RF Optimization profile: enables or disables load balancing based on a user-defined number of clients or
degree of AP utilization on an AP. Use this profile to detect coverage holes, radio interference and STA
association failures and configure Received signal strength indication (RSSI) metrics.
l RF Event Thresholds profile: defines error event conditions, based on a customizable percentage of low-
speed frames, non-unicast frames, or fragmented, retry or error frames. For additional information on
configuring this profile, see RF Event Configuration on page 604.
l AM Scanning: Dell 802.11n APs and non-11n APs in AM-mode support the TotalWatch scanning feature
giving them the ability to scan all channels of the RF spectrum, including 2.4-and 5-GHz bands as well as the
4.9-GHz public safety band. The AM Scanning profile enables this feature, and defines the dwell types for
different channel types.
Wireless LAN Profiles
The Wireless LAN collection of profiles configure WLANs in the form of virtual AP profiles. A virtual AP profile
contains an SSID profile which defines the WLAN, the high-throughput SSID profile, and an AAA profile that
defines the authentication for the WLAN.
Unlike other profile types, you can configure and apply multiple instances of virtual AP profiles to an AP group
or to an individual AP.
l 802.11k profile: manages settings for the 802.11k protocol. The 802.11k protocol allows APs and clients
to dynamically query their radio environment and take appropriate connection actions. For example: In a
802.11k network if the AP with the strongest signal reaches its CAC (Call Admission Control) limits for voice
calls, then on-hook voice clients may connect to an under utilized AP with a weaker signal. You can configure
the following options in 802.11k profile:
l Enable or disable 802.11K support on the AP
l Forceful disassociation of on-hook voice clients
