Can VACL work properly when inter-subnet roaming?

Guest

Hello!

I just learn the wireless roaming. I have a doubt about inter-subnet
roaming.

Refer to http://www.cisco.com/en/US/i/100001-200000/150001-160000/155001-156000/155264.jpg.

When inter-subnet roaming occurs, the wireless client moves from a
subnet/VLAN-x to subnet/VLAN-y. Besides, after roaming, data sent from
the client will be fowarded as VLAN-y data, even though data destined
to the client still belong to VLAN-x.

Assume that a VACL has been configured previously to impose some
effects over the client, but the VACL only filts data in VLAN-x. After
inter-subnet roaming, all data generated by the client are forwarded
as VLAN-y's data, it seems that the VACL cannot filt them any longer.

Is my understanding correct?

Thank you.
