Working w ith RF Manage ment Profiles
The profilesco nfigureradio tuning and calibration, AP load balancing, and RSSI metrics.
l802.11a radio profile—Defines AP radio settings for the 5 GHz frequency band, includingthe Adaptive Radio
Management(ARM) profile and the high-throughput (802.11n) radio profile. For additional information on
configuringthis profile,see "802.11a and 802.11g RF ManagementProfiles" on page 42 4.
l802.11g radio profile—Defines AP radio settings for the 2.4 GHz frequency band, includingthe Adaptive Radi o
Management(ARM) profile and the high-throughput (802.11n) radio profile. Each 802.11a and 802.11b radio
profilei ncludesa reference to an Adaptive R adio Management(A RM) profile.
If you want the ARM feature to dynamically select the best channeland transmission power for the radio, verify
that the 802.11a/802.11g radio profile referencesan active and enabled ARM profile. If you want to manually
select a channelfor each A P group, create separate 802.11a and 802.11g profiles for each AP group and assign a
differenttransmission c hannelfor each profile. For additional information on configuring this profile, see
"802.11a and 802.11g RF Management Profiles" on page 424.
lARM profile—Defines the Adaptive Radio Management (ARM) settings fors canning,acceptable coverage levels,
transmission power and noise thresholds. In most network environments, ARM does not need any adjustments
fromi ts factory-configureds ettings. 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,
referto Adaptive Radio Management (ARM) on page 346.
lHigh-throughputradio profile—Manages high-throughput(80 2.11n) radio settings for 802.11n-capable APs. A
high-throughputprofile determines 40 Mhz tolerance settings, and controls whether or not the APs using this
profilewi lladvertise intolerance of 40 MHz operation. (Thiso ption is disabledby default, allowing 40 MHz
operation.) For additional information on configuring this profile, see "Configuringa High-ThroughputVirtual
AP" on page 340.
lRF optimization profile—Enables or disables load balancingbased o n a user-definednumber of clients or degree
of AP utilization on an AP . Use this profile to detect coverage holes, radio interference and STA association
failuresand configure Received signal strength indication (R SSI) metrics.
lRF event thresholds profile—Defines error event conditions, based on a customiz ablepercentage of low-speed
frames,non-unicast frames, or fragmented,retry or error frames. For additional information on configuring this
profile,see "RF E vent Configuration"o n page 433.
lSpectrum Profile—Defines the ageout times for devices seen by a spect rummonito r.For more i nformation
