In the WebUI
To assign an ARM profile to an AP group via the Web User Interface:
1. Select Configuration > Wireless > AP Configuration.
2. Click the AP Group tab if it is not already selected.
3. Click the Edit button beside the AP group to which you want to assign the new ARM profile.
4. Expand the RF Management section in the left window pane.
5. Select a radio profile for the new ARM profile.
n To assign a new ARM profile to an AP group’s 802.11a radio profile, expand the 802.11a radio profile
section.
n To assign a new ARM profile to an AP group’s 802.11g radio profile, expand the 802.11g radio profile
section.
6. Select Adaptive Radio management (ARM) Profile.
7. Click the Adaptive Radio Management (ARM) Profile drop-down list in the right window pane, and
select a new ARM profile.
8. (Optional) repeat steps 6–8 to assign an ARM profile to another 802.11a or 802.11g radio profile.
9. Click Apply.
You can also assign an ARM profile to an AP group by selecting a radio profile, identifying an AP group assigned
to that radio profile, and then assigning an ARM profile to one of those groups.
1. Select Configuration > Advanced Services> All Profiles.
2. Select RF Management, and then expand either the 802.11a radio profile or 802.11b radio profile.
3. Select an individual radio profile name to expand that profile.
4. Click Adaptive Radio Management (ARM) Profile, and then use the Adaptive Radio management
(ARM) Profile drop-down list in the right window pane to select a new ARM profile for that radio.
In the CLI
To assign an ARM profile to an AP group via the command-line interface, access the CLI in config mode and
issue the following commands where <ap_profile> is the name of the AP group, and <arm_profile> is the
name of the ARM profile you want to assign to that radio band.:
(host)(config) #rf dot11a-radio-profile <ap_profile>
arm-profile <arm_profile>
and
(host)(config) #rf dot11g-radio-profile <ap_profile>
arm-profile <arm_profile>
Using Multi-Band ARM for 802.11a/802.11g Traffic
It is recommended that you use the multi-band ARM assignment and Mode Aware ARM feature for single-
radio APs in networks with traffic in the 802.11a and 802.11g bands. This feature allows a single-radio AP to
dynamically change its radio bands based on current coverage on the configured band. This feature is enabled
via the AP's ARM profile.
When you first provision a single-radio AP, it initially operates in the radio band specified in its AP system
profile. If the AP finds adequate coverage on multiple channels in its current band of operation, the mode-
aware feature allows the AP to temporarily turn itself off and become an AP Air Monitor (APM). In AP Monitor
mode, the AP scans all channels across both bands to verify that each channel meets or exceeds its required
level of acceptable radio coverage (as defined by the in the ARM profile).
