Service Requirements

When users attempt to access the WLAN, they can use 802.1X clients for authentication. After entering the correct user names and passwords, users can connect to the Internet. Furthermore, users' services are not affected during roaming in the coverage area.

Networking Requirements

AC networking mode: Layer 2 bypass mode
DHCP deployment mode: The AC functions as the DHCP server to assign IP addresses to APs, and SwitchB functions as the DHCP server to assign IP addresses to STAs.
Service data forwarding mode: direct forwarding
WLAN authentication mode: WPA-WPA2+802.1X+AES

Configuration Roadmap

Configure network interworking.
Configure the AC and SwitchB to assign IP addresses to APs and STAs, respectively.
Configure APs to go online.
Configure 802.1X authentication on the AC.
Configure third-party server interconnection parameters.

The AC and server must have the same RADIUS shared key.

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 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.
- In direct forwarding mode, you are advised to configure multicast packet suppression on switch interfaces connected to APs.
- In tunnel forwarding mode, you are advised to configure multicast packet suppression in traffic profiles of the AC.
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?.
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.
In 802.1X authentication scenarios, EAP packets are forwarded to the AC through a CAPWAP tunnel. Therefore, ensure that service VLANs are created on the AC regardless of the data forwarding mode.

Procedure

Configure network interworking.

Configure third-party server interconnection parameters.
For the detailed configuration, see the related product documentation.
Verify the configuration.
- The WLAN with SSID wlan-net is available for STAs connected to the AP.
- The wireless PC obtains an IP address after it associates with the WLAN.
- Use the 802.1X authentication client on a STA and enter the correct user name and password. The STA is authenticated and can access the WLAN. You must configure the client for PEAP authentication.
  - Configuration on the Windows 7 operating system:
    1. Access the Manage wireless networks page, click Add, and select Manually create a network profile. Add SSID wlan-net. Set the authentication mode to WPA2-Enterprise, and encryption algorithm to AES. Click Next.
    2. Click Change connection settings. On the Wireless Network Properties page that is displayed, select the Security tab page and click Settings. In the Protected EAP Properties dialog box, deselect Validate server certificate and click Configure. In the displayed dialog box, deselect Automatically use my Windows logon name and password and click OK.
    3. Click OK. On the Wireless Network Properties page, click Advanced settings. On the Advanced settings page that is displayed, select Specify authentication mode, set the identity authentication mode to User authentication, and click OK.
- After wireless users connect to the network, run the display access-user access-type dot1x command on the AC to view users in 802.1X authentication mode. The user huawei has gone online successfully.
