Dell PowerConnect W-Series Aruba Instant 6.2.1.0-3.3 | User Guide

Parameter Description

Prefer 5 GHz

Selectthis option to use band steering in 5 GHz mode. On selecting this, the OAW-

IAP steers the client to 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 OAW-IAPs.

Balance Bands

Select this option is selected, the OAW-IAP tries 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.

4. For Airtime fairness mode, specify any of the following values:

Parameter Description

Default Access

Select this option to provide access based on client requests. When Air Time

Fairness is set to default access, per user and per SSID bandwidth limits are not

enforced.

Fair Access

Select this option to allocate Airtime evenly across all the clients.

Preferred Access Select this option to set a preference where 11n clients are assigned more airtime

than 11a/11g. The 11a/11g clients get more airtime than 11b. The ratio is 16:4:1.

5. For Spectrum load balancing, specify the following parameters:

Parameter Description

Spectrum load

balancing

Select Enabled to enable Spectrum load balancing on APs so that clients are

assigned to less loaded channels. When enabled, the Virtual Controller compares

whether an AP has more clients than its neighboring APs on other channels. When

the client load for an AP reaches or exceeds the threshold specified for SLB

threshold, load balancing is enabled on the AP. For more information, see Spectrum

Load Balancing on page 191.

SLB calculating

interval

The value specified for SLB calculating interval determines how often spectrum load

balancing must be calculated. The interval is specified in seconds and the default

value is 30 seconds. You can specify a value within the range of 10-600.

SLB neighbor

matching %

The value specified for SLB neighbor matching % indicates the percentage for

comparing client density of AP neighbors to determine the client load on a specific

AP channel. You can specify a percentage value within the range of 20-100. The

default value is 75%.

SLB threshold

The value specified for SLB threshold indicates the number of clients on a channel.

When the client load for an AP reaches or exceeds the specified threshold, load

balancing is enabled on the AP. You can specify a value within range of 1-20. The

default value is 2.
