Example for Configuring Portal Authentication on the Wireless Side
Portal Authentication on the Wireless Side Overview
Portal authentication, also known as web authentication, uses a Portal website to authenticate users when they go online. The users can use network resources only after they pass the authentication.
A user can access a known Portal authentication website and enter a user name and password for authentication. This mode is called active authentication. If a user attempts to access other external networks through HTTP, the device forcibly redirects the user to the Portal authentication website. This mode is called forcible authentication.
Configuration Notes
In tunnel forwarding mode, the management VLAN and service VLAN cannot be the same. If you set the forwarding mode to direct forwarding, you are not advised to configure the management VLAN and service VLAN to be the same.
In direct forwarding mode, configure port isolation on the interface directly connected to APs. If port isolation is not configured, many broadcast packets will be transmitted in the VLANs or WLAN users on different APs can directly communicate at Layer 2.
- Configure the management VLAN and service VLAN:
- In tunnel forwarding mode, service packets are encapsulated in a CAPWAP tunnel and forwarded to the AC. The AC then forwards the packets to the upper-layer network or APs. Service packets and management packets can be forwarded normally only if the network between the AC and APs is added to the management VLAN and the network between the AC and upper-layer network is added to the service VLAN.
- In direct forwarding mode, service packets are not encapsulated into a CAPWAP tunnel, but are directly forwarded to the upper-layer network or APs. Service packets and management packets can be forwarded normally only if the network between the AC and APs is added to the management VLAN and the network between APs and upper-layer network is added to the service VLAN.
- How to configure the source interface:
- In V200R005 and V200R006, run the wlan ac source interface { loopback loopback-number | vlanif vlan-id } command in the WLAN view.
- In V200R007 and V200R008, run the capwap source interface { loopback loopback-number | vlanif vlan-id } command in the system view.

For S7700, you are advised to deploy S7712 or S7706 switches for WLAN services. S7703 switches are not recommended.
For S9700, you are advised to deploy S9712 or S9706 switches for WLAN services. S9703 switches are not recommended.
Networking Requirements
As shown in Figure 3-145, the AC deployed in a public area connects to the egress gateway (Router), RADIUS server, and Portal server, and connects to the AP through SwitchA. Users can access network resources through the WLAN with the SSID of test. The gateway also functions as a DHCP server to assign IP addresses on the 10.10.10.0/24 network segment to STAs, which are managed by the AC.
Because the WLAN is too easy for users to access, there are potential security risks. To facilitate access to the WLAN, use the default security policy on the AC, in which STAs are not authenticated and data is not encrypted. To centrally manage STAs and allow only paid users to access the Internet, configure Portal authentication on the AC. Any user who attempts to access the Internet is redirected to the Portal authentication web page. A paying user connects to the Internet after entering the user name and password, and the RADIUS server starts accounting. A non-paying user must pay for the WLAN service and use the obtained user name and password to complete Portal authentication. Generally, the Portal authentication web page provides the paying function.

Configuration Roadmap
- Configure WLAN basic services so that STAs can access the WLAN. This example uses default configurations.
- Configure a RADIUS server template, apply it to an AAA domain, and use a RADIUS server to authenticate STAs' identities and perform accounting.
- Configure Portal authentication so that Hypertext Transfer Protocol (HTTP) request packets from a user are redirected to the web page of the Portal server. After the user enters identity information, the STA sends the user identity information to the RADIUS server.
Procedure
- Set the NAC mode to unified mode on the AC (default setting). Configure SwitchA and the AC to allow the AP and AC to transmit CAPWAP packets.
