Configuring ARM Features on an IAP
This section describes the following procedures for configuring ARM features:
l Band Steering on page 234
l Airtime Fairness Mode on page 234
l Client Match on page 235
l Access Point Control on page 237
Band Steering
The band steering feature assigns the dual-band capable clients to the 5 GHz band on dual-band 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 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
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 IAPs.
Balance Bands
Select this option to allow the 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
Airtime Fairness Mode
The airtime fairness feature provides equal access to all clients on the wireless medium, regardless of client type,
capability, or operating system, thus delivering uniform performance to all clients. This feature prevents the clients
from monopolizing resources. You can configure airtime fairness mode parameters through the Instant UI or CLI.
