Controller-less WLANs

The Local Probe Request Threshold specifies an SNR threshold for the probe requests. If a threshold is specified, the AP will not respond to probe requests received with SNR lower than the threshold.

This will of course affect the ability of clients farther from the AP to connect.

 

Local-probe-threshold setting helps great to address far roaming and sticky client issues.

Once we enabled this feature, it should take effect right away.

 

Here is the exact configuration from CLI:-

------------------------------------------------------

(Master) #configure terminal

Enter Configuration commands, one per line. End with CNTL/Z

 

(Master) (config) #wlan ssid-profile test

(Master) (SSID Profile "test") #local-probe-req-thresh ?

<local-probe-req-thre.. The SNR threshold below which incoming probe

                        requests will get ignored (only used if

                        local-probe-response is also enabled)

 

Normally in production environment, it is advised to enable Hide SSID along with Local-probe-threshold as some clients attach to the AP since its broadcasting the SSID (beacons).
 

This helps for client hand-off from one AP to another AP results in improved roaming. Best practice we should set this up to value of 20 or 25 to get better results.

 

To enable Hide-ssid:-

----------------------------

 

(Master) #configure t

Enter Configuration commands, one per line. End with CNTL/Z

 

(Master) (config) #wlan ssid-profile sri

(Master) (SSID Profile "sri") #hide-ssid ?
