Configuring ARM Features on a W-IAP
This section describes the following procedures for configuring ARM features:

Band Steering
The band steering feature assigns the dual-band capable clients to the 5 GHz band on dual-band W-IAPs. This
feature reduces co-channel interference and increases available bandwidth for dual-band clients, because there
are more channels on the 5 GHz band than on the 2.4 GHz band. You can configure band steering parameters
through the Instant UI or CLI.
In the Instant UI
To configure band steering:
1. In the RF>ARM >Show advanced options tab view, configure the following parameters:
Parameter Description
Prefer 5 GHz
Selectthis option to use band steering in the 5 GHz mode. On selecting this, the
W-IAP steers the client to the 5 GHz band (if the client is 5 GHz capable), but
allows the client connection on the 2.4 GHz band if the client persistently
attempts for 2.4 GHz association.
Force 5 GHz
Select this option to enforce 5 GHz band steering mode on the W-IAPs.
Balance Bands
Select this option to allow the W-IAP to balance the clients across the two radios
to best utilize the available 2.4 GHz bandwidth. This feature takes into account
the fact that the 5 GHz band has more channels than the 2.4 GHz band, and
that the 5 GHz channels operate in 40MHz, while the 2.5 GHz band operates in
20MHz.
Disabled
Select this option if you want to allow the clients to select the band to use.

2. Click OK.
In the CLI
To configure band steering:
(Instant AP)(config)# arm
(Instant AP)(ARM)# band-steering-mode {<Prefer 5 GHz>| <Force 5 GHz>|<Balance
Bands>|<Disabled>}
(Instant AP)(ARM)# end
(Instant AP)# commit apply
