Band Steering Feature
You can leave all voice-capable clients the B/G channels (where bandwidth is not a
concern) and move data-only clients to the A bands to achieve higher data rates. To
use band steering for ABGN traffic, you could use A-Steering to direct dual mode
clients with A capability to the 5GHz band and use N-Steering to direct all dual mode
clients with AN capability to the 5GHz band. Band steering is also useful for directing
multicast traffic.
Configure Band Steering with the Web UI
Band Steering is enabled on a per-ESS basis. When you create or modify an ESS, you
can enable band steering. To do this with the Web UI, follow the directions Add an
ESS with the Web UI setting the field Enable Band Steering to On. The field Band
Steering Timeout defaults to 5 seconds; this is the number of seconds that assignment
for a steered client is blocked on the forbidden band while it is unassociated. For this
command to work as clients are added, also set the field New APs Join ESS to on in
the ESS.
Configure Band Steering with the CLI
Two new CLI commands have been added for band steering. band-steering-mode
enables band steering on an ESS and band-steering-timeout sets the number of
seconds that assignment for a steered client is blocked on the forbidden band while
it is unassociated. The command band-steering-mode disable turns off band
steering. To use band steering, create an ESS with the following configuration:
