Im reading from ArubaOS 6.4 User Guide and Im confused about a topic.
We have APs and a Switch on every Floor.
APs are on Multiple Different Subnets from Controller. So, each Floor has a separate VLAN.
All switches connect to a separate interface of Router and Aruba Mobility Controller is connected behind the Router.
The controller is connected to the Router through a trunk port that carries traffic for all wireless client VLANs.
APs establish a tunnel to Controller. Which is default gateway for clients??
It says the Router is the default gateway, but which Router's interface?

By default, all client traffic is tunneled back to the controller. Clients are not aware of the ip address scheme of the physical access points that they are on. The access points only exist as a transport to get client traffic back to the controller. After it get to the controller, client traffic is placed on whatever VLAN is defined in the Virtual AP. That VLAN number determines the VLAN of the client traffic and what default gateway the client has.
For example, if the Virtual AP VLAN is 6, the client traffic is tunneled back to the controller and sent out the trunk between the layer 3 switch and the controller on VLAN 6. The client default gateway is the ip address of the layer 3 switch on VLAN 6.
I hope that makes sense.
