Example for Configuring the Shopping Mall and Supermarket IoT Solution - Indoor Navigation

Service Requirements

In a shopping mall with large areas and complex environment, it is difficult for customers to find parked cars and shops. To help customers to easily find shops or parked cars, improve customer satisfaction, and promote customers' buying intention, the shopping mall expects to provide navigation services.

To meet these requirements of the shopping mall, Huawei provides the indoor navigation solution. This solution provides customers with easy and secure Wi-Fi network access and improves customers' network experience. Additionally, an indoor navigation app is provided for customers to find shops or parked cars, improving customer satisfaction.

Networking Requirements

AC networking mode: Layer 2 in bypass mode
DHCP deployment mode: Configure an AC as the DHCP server to assign IP addresses to APs and STAs.
Service data forwarding mode: direct forwarding

Configuration Roadmap

Configure network interworking between the AC and location server, and between the location server and app server.
Configure the AC as a DHCP server to assign IP addresses to APs and STAs.
Configure the APs to go online.
Configure WLAN services.
Configure the Bluetooth terminal location function.
Configure the location server.

Configuration Notes

No ACK mechanism is provided for multicast packet transmission on air interfaces. In addition, wireless links are unstable. To ensure stable transmission of multicast packets, they are usually sent at low rates. If a large number of such multicast packets are sent from the network side, the air interfaces may be congested. You are advised to configure multicast packet suppression to reduce impact of a large number of low-rate multicast packets on the wireless network. Exercise caution when configuring the rate limit; otherwise, the multicast services may be affected.
- In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
- In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
For details on how to configure traffic suppression, see How Do I Configure Multicast Packet Suppression to Reduce Impact of a Large Number of Low-Rate Multicast Packets on the Wireless Network?.
Configure port isolation on the interfaces of the device directly connected to APs. If port isolation is not configured and direct forwarding is used, a large number of unnecessary broadcast packets may be generated in the VLAN, blocking the network and degrading user experience.
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. Only packets from the management VLAN are transmitted between the AC and APs. Packets from the service VLAN are not allowed between the AC and APs.

Procedure

Set the NAC mode to unified on the AC so that users can connect to the network properly.
```
<HUAWEI> system-view
[HUAWEI] authentication unified-mode
```
If the NAC mode is changed from traditional to unified, the unified mode takes effect after you save the configuration and restart the device.
Configure network interworking between the AC and location server, and between the location server and app server.
Configure routes based on the actual networking to ensure network interworking.

Configure the switch and AC to enable APs to communicate with the AC.

Configure the AC as a DHCP server to assign IP addresses to APs and STAs.
# Configure the DHCP server based on the address pool of a VLANIF interface.
Configure the DNS server as required. The common methods are as follows:
- In interface address pool scenarios, run the dhcp server dns-list ip-address &<1-8> command in the VLANIF interface view.
- In global address pool scenarios, run the dns-list ip-address &<1-8> command in the IP address pool view.
