Using Band Select
Band Select allows you to move to the less congested radios if your Wi-Fi radios are capable of dual
band operation. This feature improves the overall performance of the network.
When the feature is enabled, the access point suppresses the probe response to all the new clients for all
SSIDs that are Band Select-enabled.
To enable Band Select, follow these steps:
Step1 Choose Security > SSID Manager.
Step2 Click NEW to create a new SSID.
or
Choose the required SSID from the Current SSID.
Step3 Click the Band Select radio button.
Step4 Click Apply.
To assign the parameters for Band Select, follow these steps:
Step1 Choose Services > Band Select.
Step2 Check the Band Select check box.
Step3 Enter the values for the following:
•Client-Rssi—Minimum Receive Signal Strength Indicator (RSSI) required for the client to be
eligible for band select. The range is from 20 to 90.
•Cycle-Count—Number of probe beacons or frames that the access point ignores or delays. The
range is from 1 to 10.
•Cycle-Threshold (ms)—Time in milliseconds that the access point can expect each probe from the
client. The range is from 1 to 1000.
•Expire-Suppression (secs)—Time after which clients will be declared as new and may have their
probe frames delayed or ignored again. The range is from 10 to 200.
•Expire-Dual-Band (secs)—Similar to Expire-Suppression, however Expire-Dual-Band applies only
to dual band clients. The range is from 10 to 300.
Step4 Click Apply.
Beginning in privileged EXEC mode, use these commands to configure SSH using the access point CLI:
- ap(config)# dot11 band-select parameters
- ap(config-bs-profile)# cycle-count?
- ap(config-bs-profile)# cycle-threshold?
- ap(config-bs-profile)# expire-suppression?
- ap(config-bs-profile)# expire-dual-band?
- ap(config-bs-profile)# client-rssi?
