Each 802.11a and 802.11g radio profile references an Adaptive Radio Management (ARM) profile. When you
assign an active ARM profile to a mesh radio, ARM's automatic power-assignment and channel-assignment
features will automatically select the radio channel with the least amount of interference for each mesh
portal, maximizing end user performance. In earlier versions of this software, an AP with a mesh radio
received its beacon period, transmission power and 11a/11g portal channel settings from its mesh radio
profile. Mesh-access AP portals now inherit these radio settings from their dot11a or dot11g radio profiles.
Each ARM-enabled mesh portal monitors defined thresholds for interference, noise, errors, rogue APs and
radar settings, then calculates interference and coverage values and selects the best channel for its radio
band(s). The mesh portal communicates its channel selection to its mesh points via Channel Switch
Announcements (CSAs), and the mesh points will change their channel to match their mesh portal.
Although channel settings can still be defined for a mesh point via that mesh point's 802.11a and 802.11g
radio profiles, these settings will be overridden by any channel changes from the mesh portal. A mesh point
will take the same channel setting as its mesh portal, regardless of its associated clients. If you want to
manually assign channels to mesh portals or mesh points, disable the ARM profile associated with the
802.11a or 802.11g radio profile by setting the ARM profile's assignment parameter to disable. The ARM
power adjustment feature does not apply to all ARM-enabled Mesh portals. Indoor mesh portals can take
advantage of this feature to adjust power settings according to their ARM profiles, but outdoor mesh portals
will continue to run at configured power level to maximize their range.
Do not delete or modify mesh cluster profiles once you use them to provision mesh nodes. You can recover the mesh
point if the original cluster profile is still available. Aruba recommends creating a new mesh cluster profile if needed.

Default Description
No Enable or disable the radio to advertise its 802.11d (Country Information) and
802.11h (Transmit Power Control) capabilities.
No Enable or disable Channel Switch Announcements (CSAs), as defined by IEEE
802.11h. This setting enables an AP to announce that it is switching to a new
channel before it begins transmitting on that channel. This allows clients that
support CSA to transition to the new channel with minimal downtime.
4 Set the number of channel switch announcements that must be sent prior to
switching to a new channel.
1 Set the averaging interval for rate limiting management frames from this radio, in
seconds. A management frame throttle interval of 0 seconds disables rate
limiting.
20 Set the maximum number of management frames that can come in from this
radio in each throttle interval.
Yes Supported for 802.11g only, use this field to enable protection for 802.11b clients.
Disabling this protection violates the 802.11b standard and may cause
interoperability issues.
