Whenever we make any changes to the VLAN / VLAN pool of a VAP, all the users in that VAP will get disconnected.

We are testing in a lab with a controller running 6.4.x.x. We have a named vlan pool that is assigned via a VSA from the ClearPass controller. We've added a second vlan to the pool and then removed the original vlan from the pool. When we remove the original VLAN from a named vlan pool users remain connected in that VLAN until they re-authenticate. When they reauth, the controller places the user in a legitimate vlan and they get a new address. Is this the expected behavior?
