Example for Configuring an Eth-Trunk on an AP's Wired Uplink Interfaces
Service Requirements
The administrator wants to configure an Eth-Trunk on an AP's wired uplink interfaces to ensure uplink reliability.
Networking Requirements
AC networking mode: Layer 2 inline mode
Service data forwarding mode: tunnel forwarding

Configuration Roadmap
- Configure an Eth-Trunk on a switch.
- Configure an Eth-Trunk for an AP on the AC.
- Restart the AP.
- Connect the switch and AP physically.
Configuration Notes
This example is applicable to an AP with two or more wired uplink interfaces.
This example assumes that the AP has gone online and describes how to configure an Eth-Trunk on the wired uplink interfaces of the AP. Before physical connections, configure the Eth-Trunk. Otherwise, a loop will occur on the network, causing the AP to go offline.
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
- Check AP information.

Data
Check the AP's group.
Choose . Check the AP's group in AP List.
AP group name: ap-group1
AP name: AP1
- Configure an Eth-Trunk on the switch.# Create Eth-Trunk1, and add GE0/0/1 and GE0/0/2 to Eth-Trunk1.

- Configure an Eth-Trunk on the AP.
- Create wired port profile wired-port1, and add GE0 and GE1 on the AP to Eth-Trunk0.
# Choose .
# In the AP group list, select AP group ap-group1. Choose . The AP Wired Port Configuration List page is displayed.
# Select GE0. The GE0 configuration page is displayed.
# Click Create and create AP wired port profile wired-port1. Click OK to return to the GE0 configuration page.
# Set Enable Eth-Trunk to ON.
Click OK. In the dialog box that is displayed, click OK.
# Bind AP wired port profile wired-port1 to GE1 in the same way, and set Enable Eth-Trunk to ON for GE1.
- Add Eth-Trunk0 to VLAN 100.
# Choose .
# In the AP group list, select AP group ap-group1. Choose . The AP Wired Port Configuration List page is displayed.
# Click Create and create AP wired port profile wired-port2. Click OK to return to the configuration page.
# Click Advanced Configuration. Under Added VLAN ID, add VLAN 100 in tagged mode, and set Port mode to Root.
Click OK. In the dialog box that is displayed, click OK.
- Create wired port profile wired-port1, and add GE0 and GE1 on the AP to Eth-Trunk0.
- Restart the AP.
The configuration on the AP's wired interfaces takes effect only after the AP is restarted.
# Choose .
# Select AP1 and click Restart. In the dialog box that is displayed, click OK to restart the AP.
- Connect the switch and AP physically.
