Issue Description

How can I use an AR router as an AC to manage APs through a Layer 3 interface? (V200R009)

Networking Requirements

In Figure 1, an AC directly connects to an AP through a Layer 3 Ethernet interface. WLAN basic services need to be deployed to implement mobile office.

Specific requirements are described below:

 A wireless network named HUAWEI is provided.

 The AP obtains an IP address in

 IP addresses in are assigned to employees.
