l The client is not currently associated on the 2.4Ghz radio of this AP.
n Balance-bands: In this band steering mode, the AP uses client load and RSSI information balance the
clients across the two radios and best use the available 2.4G bandwidth. This feature takes into account the
fact that the 5Ghz band has more channels than the 2.4 Ghz band, and that the 5Ghz channels operate in
40MHz while the 2.4Ghz band operates in 20MHz.
Enabling Band Steering
Band steering is configured in a virtual AP profile. Use the following procedures to enable or disable Band
Steering using the WebUI or command-line interfaces.
In the WebUI
1. Select Configuration > Advanced Services > All Profiles. The All Profile Management window opens.
2. Select Wireless LAN to expand the Wireless LAN section.
3. Select Virtual AP profile to expand the Virtual AP Profile section.
4. Select the name of the Virtual AP profile for which you want to enable band steering.
(To create a new virtual AP profile, enter a name for a new profile in the Profile Details window, then click
Add. The new profile will appear in the Profiles list. Select that profile to open the Profile Details pane.)
5. In the Profile Details pane, select Band Steering to enable this feature, or uncheck the Band Steering
checkbox to disable this feature.
6. Once band steering is enabled, click the steering mode drop-down list and select the desired steering
mode.
7. Click Apply.
In the CLI
Use the following commands to enable band steering via the command-line interface.
(host)(config) #wlan virtual-ap <profile> band-steering
(host)(config) #wlan virtual-ap <profile> steering-mode
Dynamic Bandwidth Switch
ARM’s dynamic bandwidth switch feature provides capability for ARM to detect the 20MHz interferer by
reading the Clear Channel Assessment (CCA) statistics and other radio statistics. Once the signatures are
detected, ARM moves to another 80MHz channel or downgrade to 40MHz. This feature only works when
dynamic-bw parameter is enabled and ARM is set to use 80MHz assignment.
Traditionally, when the bandwidth is configured, the operating channel bandwidth is fixed and is not changed.
If ARM decides to downgrade the bandwidth to 40MHz, then it will upgrade back to 80MHz after the clear time based
on the volume of the traffic.
Enabling Dynamic Bandwidth Switch
Use the following procedures to enable or disable dynamic bandwidth switch using command-line interfaces.
In the CLI
Use the following commands to enable and set dynamic bandwidth switch:
(host) (config) #rf arm-profile default
(host) (Adaptive Radio Management (ARM) profile "default") #dynamic-bw
(host) (Adaptive Radio Management (ARM) profile "default") #dynamic-bw-beacon-failed-thresh
