Configuring ARM Features on an AP
21.2.1
The band steering feature assigns the dual-band capable clients to the 5 GHz band on dual-
band APs. 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 that on the
2.4 GHz band. You can configure band steering parameters through the SCALANCE W UI
or the CLI.
To configure band steering:
1. In the
RF > ARM > Show advanced options
tab view, configure the following parameters:
Prefer 5 GHz Select this option to use band steering in the 5 GHz mode. On selecting this, the
AP 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
Select this option to enforce 5 GHz band steering mode on the APs.
Balance
Bands
Select this option to allow the AP 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 40 MHz, while the 2.4 GHz band operates in 20 MHz.
Select this option if you want to allow the clients to select the band to use.
2. Click

To configure band steering:
(scalance)(config)# arm
(scalance)(ARM)# band
-steering-mode {<Prefer 5 GHz>| <Force 5 GHz>|<Balance
Bands>|<Disabled>}
(scalance)(ARM)# end (scalance)# commit apply
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 SCALANCE W UI or the
CLI.
