The Answers are inline.
Interesting. So this VLAN 20 is only configured on the Controller. Correct?
yes.
The IP Address assigned to the User Laptop will be issued by who? DHCP server on teh controller side or the controller
The Core DHCP Server? If the code DHCP is provide ip address to vlan 20 in the controller.
That VLAN 20 doesn't it need to be seen somewhere on the Wired Network. Even the Core Switch and not neccessarily on the Closets?
No. the reason is all the traffic is tunneled to the controller on AP's VLAN.
If they need to access the Internet or Servers on the Corporate Network, shouldn't the Core Switch know about this VLAN and have an IP Address existing on the VLAN?
SInce the traffic is tunneled they will get IP from the VLAN 20 through the tunnel from controler side. No need for the core switch to know abt this vlan.
Sorry for the too many questions!
