Spectrum Configurations And Prerequisites; Setting Up A Permanent Spectrum Dell Ap Group - Dell PowerConnect W-Airwave User Manual

The spectrum analyzer is used in conjunction with Adaptive Radio Management (ARM) technology. While the
spectrum analyzer identifies and classifies Wi-Fi and non-Wi-Fi sources of interference, ARM automatically
ensures that APs serving clients will stay clear of interference.
Individual APs or groups of APs can be converted to dedicated spectrum monitors through the dot11a and dot11g
radio profiles of that AP or AP group, or through a special spectrum override profile.
Each 802.11a and 802.11g radio profile references a spectrum profile, which identifies the spectrum band the
radio will monitor and analyze, and defines the default ageout times for each monitored device type. By default,
an 802.11a radio profile references a spectrum profile named default-a (which configures the radio to monitor the
upper channels of the 5 GHz radio band), and an 802.11g radio profile references a spectrum profile named
default-g (which configures the radio to monitor all channels the 2.4 GHz radio band).
Most interference will occur in the 2.4 GHz radio band.
For more information about Spectrum analysis and ARM technology, refer to the Dell PowerConnect W-Series
ArubaOS 6.0 User Guide at support.dell.com/manuals.

Spectrum Configurations and Prerequisites

The following prerequisites must be in place to configure an AP to run in spectrum mode in AMP:
The AP must be in Manage Read/Write mode.

The AP's associated controller must have an RFprotect license, and must run ArubaOS 6.0 or later.

Dell PowerConnect W UI Config must be enabled for that AP's group in the Groups > Basic page.

There are three main situations in which you would set one or more devices to Spectrum mode in AMP:
Dell AP Groups running permanently with the default Spectrum profile

Individual APs running temporarily in Spectrum mode while part of a Dell PowerConnect W AP Group set to

ap-mode
Controller-level Spectrum Overrides (an alternative to creating new Dell PowerConnect W AP groups or new

radio profiles for temporary changes)

Setting up a Permanent Spectrum Dell AP Group

If you have multiple supported Dell PowerConnect W-Series APs in multiple controllers that you want to run in
Spectrum mode over the long run, you create a special Dell PowerConnect W AP group and set up a profile that
is set to spectrum-mode and references the default Spectrum profile. Set up more than one profile if you want to
utilize both radio bands in Spectrum mode.
If you use an 802.11a or 802.11g radio profile to create a group of spectrum monitors, all APs in any AP group
referencing that radio profile will be set to spectrum mode. Therefore, best practices are to create a new 802.11a
or 802.11g radio profile just for spectrum monitors.
If you have Global Dell PowerConnect W Configuration enabled in AMP Setup > General, create the
configuration below, then go to the controller's group's Dell PowerConnect W Config page and select the newly
created Dell PowerConnect W AP Group.
Perform these steps to set the AP group to use the default Spectrum profile settings:
1. In Groups > Dell PowerConnect W Config, select Add New Dell PowerConnect W AP Group.
2. Give the new Group a name (like "Spectrum APs") and select the plus sign next to the 802.11a Radio Profile
to create a new radio profile.
3. Enter a name under the General Settings section of Profiles > RF > 802.11a/g Radio.
4. In the Other Settings section, change the Mode field from ap-mode to spectrum-mode, as illustrated in
