Agile Distributed Wi-Fi Coverage
This section describes how to deploy agile distributed Wi-Fi coverage in a native AC solution. For details about deploying the native AC solution, see Native AC Solution: Core Switches Function as the Gateway for Wired and Wireless Users. In this example, the networking is similar to that in the native AC solution, but AP2 is used as a central AP to provide access to RUs deployed in hotel guest rooms, campus dormitories, and hospital wards. If more RUs are involved, the central AP can be connected to a switch for capacity expansion.

Procedure
- Configure network connectivity and WLAN services on AP1 and AP2. For details, see Native AC Solution: Core Switches Function as the Gateway for Wired and Wireless Users.
The following describes how to configure RUs and the access switch.
- Configure Switch to enable Layer 2 communication between the central AP and RUs. If a Huawei switch is used, this configuration can be skipped as interfaces on Huawei switches are added to VLAN 1 by default and can communicate at Layer 2. If a non-Huawei switch is used, perform the configuration to enable Layer 2 communication of uplink and downlink interfaces.On the network between the central AP and RUs, service packets of STAs must be properly forwarded. This example uses the tunnel forwarding mode. Therefore, you do not need to configure packets in service VLANs to pass between the central AP and RUs. If the direct forwarding mode is used, configure packets in the service VLANs to pass between the central AP and RUs. The configuration varies depending on the central AP model as follows:
For a gigabit central AP, such as AD9430DN-24, no configuration is required on Switch. All packets from RUs are transmitted to the central AP through the MAC-IN-MAC tunnel. Therefore, you only need to allow packets in the service VLANs to pass on the central AP in the uplink direction.
For a 10GE central AP, such as AD9431DN-24X, add the uplink and downlink interfaces on Switch to the service VLANs. Service packets are forwarded in the upstream direction of an RU. Therefore, packets in the service VLANs must be allowed in the uplink direction of RUs.
- Configure names for the RUs and add them to the AP group.

- Run the display ap all command to check the RU state. If the State field is displayed as nor, the RUs go online properly.

After STAs find and associate with the SSID, wireless users can access the agile distributed Wi-Fi network.
