Seeking any feedback on the "Controller Assisted Mobility" feature which can be enabled on WLAN>Client Settings.
I have a older Distribution Center site running 2 RFS7000s. Site has 3 buildings assigned to their own unique RF Domains. Building 1 has 60 AP621s, Building 3 has 30 AP621s and Building 3 has 20 AP6522s. All APs are configured for IPLayer3/MintLevel1 adoption. The main WLAN is tunnelled back to the controller and configured with a VLAN pool of 4 VLANs. Problems occur when forklifts move between RF domains, and on recent rare occasions MU disassociations result in MUs being assigned to a new VLAN. I've seen the following webpage https://extremeportal.force.com/ExtrArticleDetail?an=000064277 which recommends implementing Controller Assisted Mobility for these issues, but when implemented I can't see any difference in the GUI or way of confirming if a roaming database is being maintained by the controller. any feedback would be appreciated, thanks.

what controller assisted mobility does is actually a database of clients and their vlan / wlan assignation.
That helps controller and APs to effectively share information across RF-Domains, which are borders of WNMP updates.
You can check your mobility database using below command and see if populated correctly
show wireless mobility-database
Let us know if you have any concerns about that.

Ondrej

I believe this is until the client "decay" occurs.
Basically once there is traffic seen from the MAC it is on, then there is inactivity-timeout to be measured and then the client is gone.

How long are details stored in this database to enable smooth roaming?
