Networking Requirements

A school plans to deploy a WLAN to cover its dormitory building. However, the dormitory building has a high density of rooms, and WLAN signals are likely to attenuate severely when passing through obstacles between rooms, such as walls.

As shown in Figure 4-1, the central AP connects to and supplies PoE power for remote units (RUs). All RUs (one for each room) and the central AP are uniformly managed by the AC to provide a high-quality WLAN.

Data Planning

Item	Data
DHCP server	The central AP functions as a DHCP server to assign IP addresses to RUs and STAs.
IP address pool for RUs	10.23.100.2-10.23.100.254/24
IP address pool for STAs	10.23.101.2-10.23.101.254/24
Management VLANs for APs	VLAN 100
AP group	Name: default Referenced profiles: VAP profile wlan-net and regulatory domain profile default
Regulatory domain profile	Name: default Country code: CN
SSID profile	Name: wlan-net SSID name: wlan-net
Security profile	Name: wlan-net Security policy: WPA2+PSK+AES Password: a1234567
VAP profile	Name: wlan-net Service VLAN: VLAN 101 Referenced profiles: SSID profile wlan-net and security profile wlan-net

Configuration Roadmap

The configuration roadmap is as follows:

Configure RUs to go online on the central AP using the configuration wizard.
Configure WLAN services on the central AP using the configuration wizard.
Deliver the WLAN services to the RUs and verify the configuration.

Procedure

Configure system parameters for the central AP.
1. Configure basic parameters for the central AP.
  # Choose Configuration > Config Wizard > Central AP. The Basic Central AP Configuration page is displayed.
  
  # Set Country/Region based on actual situations. For example, set Country/Region to China. Set System time to Manual and Date and time to PC Time.
  
  # Click Next. The Port Configuration page is displayed.
2. Configure interfaces.
  # Select GigabitEthernet0/0/1 and expand Batch Modify. Set Interface type to Trunk and add GigabitEthernet0/0/1 to VLAN 100.
  
  If the central AP and RUs are directly connected, set the default VLAN of the interfaces connected to the RUs to the management VLAN (VLAN 100 in this example).
  
  In V200R019C10 and later versions, you need to set the default VLAN to the management VLAN 100 and allow packets from service VLAN 101 to pass through.
  
  # Click Apply. In the dialog box that is displayed, click OK.
  
  # Set Interface type of GigabitEthernet0/0/2 to Trunk and add the interface to VLAN 100 in the same way.
  
  # Click Next. The Network Interconnection Configuration page is displayed.
3. Configure network connectivity.
  # Click Create under Interface Configuration. The Create Interface Configuration page is displayed.
  
  # Set the IP address of VLANIF 100 to 10.23.100.1/24. Set DHCP status to ON and DHCP type to Interface address pool.
  
  # Click OK. Set the IP address of VLANIF 101 to 10.23.101.1/24 and configure the interface address pool on VLANIF 101 in the same way.
  
  Configure the DNS server address as required.
  
  # Click Next. The Central AP Source Address page is displayed.
4. Configure the central AP source address.
  # Set AP Manage VLAN to 100.
  
  # Set Central AP source address to VLANIF100. In V200R019C10 and later versions, you also need to configure the source IP address.
  
  # Click Next. The Confirm Settings page is displayed.
5. Confirm the configuration.
  # Confirm the configuration and click Continue With AP Online.
Configure APs to go online.
1. Configure APs to go online.
  # Click Batch Import. The Batch Import page is displayed. Click to download an AP template file to your local computer.
  # Fill in the template file with AP information according to the following example. To add multiple APs, fill in the file with information about the APs.
  - AP MAC address: fcb6-9897-c520
  - AP SN: 21500826402SF4900166
  - AP Name: area_1
  - AP Group: default
  If you set AP authentication mode to MAC address authentication, the AP's MAC address is mandatory and the AP's SN is optional.
  If you set AP authentication mode to SN authentication, the AP's SN is mandatory and the AP's MAC address is optional.
  
  You are advised to export the radio ID, AP channel, frequency bandwidth, and power planned on WLAN Planner to a .csv file, and then enter them in the template file. Set the longitude and latitude as required.
  # Click next to Import AP File, select the template file with AP information, and click Import.
  
  # On the page that displays the template import result, click OK.
  
  # Click Next. The Group APs page is displayed.
  
  # AP group information has been added in the template file. Click Next. The Confirm Configurations page is displayed.
2. Confirm the configuration.
  # Confirm the configuration and click Continue With Wireless Service Configuration.
Configure WLAN services.
# Click Create. The Basic Information page is displayed.

# Set the SSID name and service VLAN ID.

# Click Next. The Security Authentication page is displayed.

# Set Security settings to Key (applicable to personnel networks), select the AES mode, and set the key.

# Click Next. The Access Control page is displayed.

# Set Binding the AP group to default.

# Click Finish.
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. Choose Monitoring > User. In User Distribution, set the search criteria to AP Name, enter area_1, and click . You can see that the STA goes online successfully.
