ArubaOS Switch – Technical Differentiators
In traditional campus networks, access switches forward client traffic to and from the distribution layer switches. On the other hand, the Aruba campus mobility architecture encapsulates wireless client traffic between APs and mobility controllers using tunnels. Tunneled Node is an ArubaOS-Switch feature that allows network administrators to implement the same encapsulation scheme used in the mobility architecture. This enables a unified policy enforcement point for traffic from both wired and wireless clients. In its current implementation, tunneled node allows for the configuration of per-user tunnels between an access switch and an Aruba mobility controller.
