Understanding VPN Features
As APs use a VC architecture, the AP network does not require a physical controller to
provide the configured WLAN services. However, a physical controller is required for
terminating Virtual Private Networks (VPN) tunnels from the AP networks at branch locations
to datacenters, where the controller acts as a VPN concentrator.
When a VPN is configured, the AP acting as the VC creates a VPN tunnel to an Mobility
Controller in your corporate office. The controller acts as a VPN endpoint and does not
supply the AP with any configuration.
The VPN features are recommended for the following setups:
● Enterprises with many branches that do not have a dedicated VPN connection to the
corporate office.
● Branch offices that require multiple APs.
● Individuals working from home and, connecting to the VPN.
The survivability feature of APs with the VPN connectivity of RAPs allows you to provide
corporate connectivity on non-corporate networks
