Configuring Band Selection
• You can enable both band selection and aggressive load balancing on the controller. They run
independently and do not impact one another.
Using the GUI to Configure Band Selection
To configure band selection using the controller GUI, follow these steps:
Step 1 Choose Wireless > Advanced > Band Select to open the Band Select page (see Figure 4-21).
Figure 4-21 Wireless > Advanced > Band Select Page
Step 2 In the Probe Cycle Count text box, enter a value between 1 and 10. The cycle count sets the number of
suppression cycles for a new client. The default cycle count is 2.
Step 3 In the Scan Cycle Period Threshold (milliseconds) text box, enter a value between 1 and 1000
milliseconds for the scan cycle period threshold. This setting determines the time threshold during which
new probe requests from a client come from a new scanning cycle. The default cycle threshold is 200
milliseconds.
Step 4 In the Age Out Suppression (seconds) text box, enter a value between 10 and 200 seconds. Age-out
suppression sets the expiration time for pruning previously known 802.11b/g clients. The default value
is 20 seconds. After this time elapses, clients become new and are subject to probe response suppression.
Step 5 In the Age Out Dual Band (seconds) text box, enter a value between 10 and 300 seconds. The age-out
period sets the expiration time for pruning previously known dual-band clients. The default value is 60
seconds. After this time elapses, clients become new and are subject to probe response suppression.
Step 6 In the Acceptable Client RSSI (dBm) text box, enter a value between –20 and –90 dBm. This parameter
sets the minimum RSSI for a client to respond to a probe. The default value is –80 dBm.
