Hello everyone,
Today I will share with you the example for configuring Layer 2 tunnel forwarding in bypass mode.
Networking Requirements
The customer must lay out a large number of network cables to deploy a wired network that does not support flexible user access. Deployment of network cables requires huge costs and human resources. The customer wants to use an AC and a Fit AP to deploy a WLAN network, which can reduce deployment costs, improve access flexibility, and enhance network maintainability.
As shown in Figure 18-1, the aggregation switch connects to the upper-layer network and an AC connects to the aggregation switch in bypass mode. An AP connects to the AC through the access switch and aggregation switch. The AP and AC communicate through a Layer 2 network and the AP and AC belong to the management VLAN 100. Tunnel forwarding is used to effectively manage data packets.

Data Preparation
Configuration Roadmap
The configuration roadmap is as follows:
1. Use the configuration wizard to configure the AP to go online on the AC.
2. Use the configuration wizard to configure the WLAN service on the AC.
3. Deliver the WLAN service to the AP and verify the configuration.
NOTE:
During AP deployment, you can manually specify the working channels of the APs according to network planning situations or configure the radio calibration function to enable the APs to automatically select the optimal channels.
If you use the radio calibration function, perform the following steps after delivering configurations to all APs:
1. Choose WLAN Service > Radio Profile. On the displayed Radio Profile List page, click Refresh and set the channel mode and power mode to auto.
2. Click Device Management > AP Management > Radio Calibration. The Radio Calibration page is displayed.
In Radio Calibration Settings, set Calibration mode to Manual and click Start. Manual radio calibration is triggered.
3. APs finish radio calibration one hour after the radio calibration is manually triggered. After that, you can perform either of the configurations:
(Recommended) change the radio calibration mode to scheduled calibration and configure the APs to perform radio calibration in off-peak hours, for example, between 00:00 am and 06:00 am.
Manually fix the working channels of APs: set the channel mode and power mode to Fixed mode in the radio profile. If a new AP gets online, repeat step 2.
Procedure
1. Configure the access switch, aggregation switch, and router.
# Add GE0/0/1 and GE0/0/2 on the access switch to VLAN 100 (the default VLAN of GE0/0/1).
# Add GE0/0/1 and GE0/0/2 on the aggregation switch to VLAN 100.
# Add GE0/0/2 and GE0/0/3 on the aggregation switch to VLAN 101.
# Configure an IP address 192.168.101.2/24 for GE1/0/0 on the router.
2. Configure the AP to go online on the AC.
a. Choose Configuration Wizard > Configuration Wizard > AP Online Configuration Wizard. The AP Online Configuration Wizard page is displayed.
b. Configure the Ethernet interface.
# On the Configure Ethernet Interface page, click
next to GigabitEthernet0/0/1 to add the interface to VLAN 100 and VLAN 101 in tagged mode.
c. Configure virtual interfaces.
# Click Create on the Configure Virtual Interface page. The Create Virtual Interface page is displayed.
# Configure an IP address 192.168.100.1/24 for VLANIF 100.
# Configure an IP address 192.168.101.1/24 for VLANIF101.
# Click Next.
d. Configure DHCP.
# Click Create on the Configure DHCP page. The Create IP Pool page is displayed.
# Configure an IP address pool for VLANIF 100.
# Configure an IP address pool for VLANIF 101. Specify that the IP address 192.168.101.2 in this address pool cannot be automatically assigned to STAs.
# Click Next.
e. Configure the AC.
f. Confirm the settings.
On the Confirm Settings page, confirm that the settings are correct and then click Finish.
3. Configure a static route.
# Choose IP Service > Route > Static Route Configuration to create a static route.
4. Configure the WLAN service.
a. Choose Configuration Wizard > Configuration Wizard > WLAN Configuration Wizard. The WLAN Configuration Wizard page is displayed.
b. Select Common WLAN Service and click Next.
c. Add the AP.
# Click Create on the Configure AP page. The Create AP page is displayed.
# Set AP type to AP6010DN-AGN and MAC address to 60de-4476-e360 on the Create AP page to add the AP.
Select the AP and click Next.
d. Configure the radio.
# Select 2.4 GHz.
# Create a radio profile named radio. Create a WMM profile named wmm and use the default settings in the profile.
# Click Next.
e. Configure the WLAN service.
# On the Configure WLAN Service page, click Create to create a service set.
# Create a traffic profile named traffic.
# Create a security profile named security.
# Create an ESS interface.
# Select the created security profile, traffic profile, ESS interface, click Advanced, and set Forwarding mode to Tunnel.
# Click OK and then click Next.
f. Confirm the settings.
# Confirm that the settings are correct, and then click Finish. In the message that is displayed, confirm that the configuration is to be delivered to the AP.
5. Enable radio calibration to allow APs to automatically select optimal channels.
# Click Device Management > AP Management > Radio Calibration. The Radio Calibration page is displayed.
In Radio Calibration Settings, set Calibration mode to Manual and click Start. Manual radio calibration is triggered.
# Click Real-Time Channel And Power List. The real-time channel and power list is displayed. Check the current working channel and the power of the radio. Assume that there are three online APs on the AC. The list shows that AP channels have been automatically assigned through the radio calibration function.
# APs finish radio calibration one hour after the radio calibration is manually triggered. Then, set Calibration mode to Periodic and Calibration time to 3:00 am.
# Click Apply. The configuration is complete.
6. Verify the configuration.
a. The WLAN with the SSID huawei is available for the STA.
b. The STA can associate with the WLAN and obtain an IP address 192.168.101.x/24 and its gateway address is 192.168.101.1.
c. Choose Terminal Management > Terminal Management > STA Management. You can see that the STA goes online successfully and obtains an IP address.
That is all I want to share with you! Thank you!
