Hi all,

We have ZD 3000 and about 50 APs. For high destiny environment, i've configure smart roam + bss min-rate (following this article: https://forums.ruckuswireless.com/ruckuswireless/topics/bss_minrate_vs_smart_roam)

1/ The config result is below:
In AP R310: show config for smartroam & bss min-rate (wlan0: 2.4Ghz | wlan32: 5Ghz)

rkscli: get bss-minrate wlan0
wlan0 BSS Min Rate: 5500 kbps
OK

rkscli: get bss-minrate wlan32
wlan32 BSS Min Rate: 5500 kbps
OK

rkscli: get roam_enable wlan0
wlan0: SmartRoam for sticky clients: Enabled
OK

rkscli: get roam_factor wlan0
wlan0: Roam Factor (scale=1-10): 5
(Lower factor means more stickiness)
OK

rkscli: get roam_enable wlan32
wlan32: SmartRoam for sticky clients: Enabled
OK

rkscli: get roam_factor wlan32
wlan32: Roam Factor (scale=1-10): 5
(Lower factor means more stickiness)
OK

2/ The result when client connect to this AP

rkscli: get client-info wlan0

=> Many client connect this AP with low RSSI (< 20 db). If Smart-Roam is working well, those clients need to be disconnected.

In monitor tab (from ZD3000), i see this AP has 101 clients connected, but those client is not real. I search some client mac-address on whole system, and can't found any logs in any devices (Access switch, Core Switch or Internet gateway).
When i reboot this AP, number of clients will be reduce to 5 or 6.

So, please help me to figure out, why this AP keep remain old clients.

Thanks a lot!
