Fat AP and Cloud AP V200R019C10 Web-based Configuration Guide

Example for Configuring for Fat AP Layer 2 Networking (Bridging Mode)

Networking Requirements

As shown in Figure 4-1, an enterprise has deployed a wired network and now needs to connect a Fat AP to the existing network in bridging mode to provide wireless Internet access services for employees.

The requirements are as follows:

A WLAN named wlan-net is available.
Router functions as a DHCP server to assign IP addresses to STAs. The Fat AP transparently transmits DHCP messages at Layer 2.

Data Planning

Item	Data
Service VLAN for STAs	VLAN 101
DHCP server	Router functions as a DHCP server to assign IP addresses to the AP and STAs.
IP address pool	10.23.101.2-10.23.101.254/24
Wireless services	SSID name: wlan-net Encryption mode: password authentication Password: a1234567

Configuration Roadmap

The configuration roadmap is as follows:

Configure Router as a DHCP server to assign IP addresses to the AP and STAs.
Configure basic WLAN services using the WLAN configuration wizard.
Associate STAs to the WLAN to verify services.

You are advised to log in to the Fat AP in wireless mode for service configuration. You can also log in to the Fat AP by directly connecting a PC to the Fat AP using network cables and then connect the Fat AP to the upstream device after services are configured and saved.

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 on switch interfaces connected to APs 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. 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?.

Procedure

Configure Router as a DHCP server to assign IP addresses to STAs.
# Configure Router as a DHCP server to assign IP addresses to the AP and STAs from the IP address pool on GE1/0/0.
Configure the DNS server as required. The common methods are as follows:
- In the interface address pool scenario, run the dhcp server dns-list ip-address &<1-8> command in the VLANIF interface view.
- In the global address pool scenario, run the dns-list ip-address &<1-8> command in the IP address pool view.
```
[Router] dhcp enable
[Router] interface gigabitethernet 1/0/0
[Router-GigabitEthernet1/0/0] ip address 10.23.101.1 24
[Router-GigabitEthernet1/0/0] dhcp select interface
[Router-GigabitEthernet1/0/0] quit
```
Configure basic WLAN services.
1. Choose Wizard > Config Wizard > Single AP Configuration. The Config Wizard page is displayed.
2. Set Internet access mode to Bridging.
3. Configure Wi-Fi signals.
  
  # Click Apply. In the dialog box that is displayed, click OK.
  
  In this example, the AP automatically obtains an IP address from the upper-layer network device. Therefore, after the configuration takes effect, the AP's IP address will change. To remotely log in to the AP for management, you are advised to associate your STA with the management SSID and access 192.168.1.1 (default IP address of the management SSID).
Verify the configuration.
1. The WLAN with the SSID wlan-net is available.
2. The STA can associate with the WLAN and obtain an IP address 10.23.101.x/24 and its gateway address is 10.23.101.1.
3. Click Monitoring. In the User area, you can see that STAs go online properly and obtain IP addresses.
