Example for Configuring Basic WLAN Location Services Based on AeroScout Tags

Configuration Process

You need to configure and maintain WLAN features and functions in different profiles. These WLAN profiles include regulatory domain profile, radio profile, VAP profile, AP system profile, AP wired port profile, WIDS profile, WDS profile, and Mesh profile. When configuring WLAN services, you need to set related parameters in the WLAN profiles and bind the profiles to the AP group or APs. Then the configuration is automatically delivered to and takes effect on the APs. WLAN profiles can reference one another; therefore, you need to know the relationships among the profiles before configuring them. For details about the profile relationships and their basic configuration procedure, see WLAN Service Configuration Procedure.

Networking Requirements

In Figure 1, the AC connects to the APs through a switch in a small warehouse.

The administrator requires that the APs collect tag information and report the information to the AeroScout location server to compute tag locations so that users can obtain the locations of all goods AeroScout Tags through maps, tables, or reports.

Configuration Roadmap

The configuration roadmap is as follows:

  • Configure basic WLAN services so that users can connect to the internal network through the WLAN.
  • Configure WLAN tag location so that APs can receive configuration information from the AeroScout location server and send the collected tag information to the AeroScout 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

  1. Configure the AeroScout location server.

    Complete location configurations on the AeroScout location server. For details, see the related document of the AeroScout location server.

  2. 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.

  3. Connect AC and AP.

    # Configure the access switch SwitchA. Add GE0/0/1, GE0/0/2, GE0/0/3 and GE0/0/4 on SwitchA to VLAN 100 (management VLAN)

    [SwitchA-GigabitEthernet0/0/4] quit

    # Configure the AC. Add GE0/0/1 to VLAN 100.

    [AC-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
    [AC-GigabitEthernet0/0/1] quit

  4. Configure the AC to communicate with the AeroScout Positioning Server.

    # Add GE0/0/2 that connects the AC and the AeroScout Positioning Server to VLAN 100.

    [AC] interface gigabitethernet 0/0/2

  5. Configure the AC as a DHCP server to allocate IP addresses to STAs and the AP.

    # Configure the AC as the DHCP server to allocate an IP address to the AP from the IP address pool on VLANIF 100, and allocate IP addresses to STAs from the IP address pool on VLANIF 101.

    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.
    [AC] dhcp enable
    [AC] interface vlanif 100
    [AC-Vlanif100] ip address 10.23.100.1 24

    The default AP authentication mode is MAC address authentication. If the default settings are retained, you do not need to run the ap auth-mode mac-auth command.

    In this example, the AP5030DN is used and has two radios: radio 0 (2.4 GHz radio) and radio 1 (5 GHz radio).
