ZF 9.9 and SmartRoam+ details?

I noticed that ZF 9.9 seems to support a new form of SmartRoam that uses 802.11v. However, the release notes don't seem to go into detail about how to configure this.

(1) Is this activated by the smart-roam command, or a different one?
(2) Is there a way to enable only the 802.11v form of SmartRoam and not the client disconnecting form? I've seen cases where clients get kicked off the network at inopportune/disruptive times (e.g. in the middle of a FaceTime call or while AirPlaying)
(3) What clients are known to support this form of 802.11v roaming?

So now the CLI reference guide and user manual have been posted, and neither seems to say anything about SmartRoam+ or 802.11v.

ZF 9.9 Smartroam may utilize 802.11k and 802.11r for fast roaming transitions,
but I have not seen any word that 802.11v would be implemented with client
communication, nor what clients might support it.

Thanks! So is it still activated by the "smart-roam" command, and keyed off the same "RSSI" based thresholds as shown in the tables in the support documents about smart-roam?

How does SmartRoam+ decide whether to use 802.11k/r/v to seamlessly transition (as described in the What's New document) versus the old way of basically ignoring / sending disassociations to a client until the client makes the right decision eventually?

John, the tech support guidelines for Smart-Roam are fairly simple. If you observe that you have certain clients that do not want to roam before getting very weak signals, we advise to use the ZD CLI configure WLAN commands 'smart-roam 3' or 'smart-roam 5'. Higher values should not be necessary. How we incorporate 802.11k/r with smart-roam is not published.

Thanks, Michael, I respect that, and can see how Ruckus's implementation of roaming is secret sauce.

Instead of trying to understand the algorithm, I'll just try it out in 9.9 and see if it meets my needs.

(I kind of alluded to it, but in 9.8 I tried it, and it was difficult to balance a setting where it was effective at forcing clients to roam *without* also having cases where it'd abruptly disconnect a client at an inopportune time)
