Service Requirements

Enterprise users can access the Internet through the WLAN to meet basic mobile office requirements. When roaming occurs in the coverage area, user services will not be interrupted.

Administrators want to deploy different SSIDs for WLAN access of guests and employees, and different authentication modes for them to ensure WLAN security.

Networking Requirements

AC networking mode: Layer 2 networking in bypass mode
DHCP deployment mode:
- The AC functions as a DHCP server to assign IP addresses to APs.
- The aggregation switch (SwitchB) functions as a DHCP server to assign IP addresses to STAs.
Service data forwarding mode: tunnel forwarding

Configuration Roadmap

Configure network interworking of the AC, APs, and other network devices.
Use the configuration wizard to configure system parameters for the AC.
Use the configuration wizard to configure the APs to go online on the AC.
Use the configuration wizard to configure WLAN services, 802.1X authentication, and MAC address-prioritized Portal authentication on the AC.
Configure authentication-free rules for an AP group.
Deliver WLAN services to the APs and verify the configuration.

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.

Procedure

Verify the configuration.
- An employee can use a STA to find the WLAN with SSID employee. After being associated with the WLAN, the STA is assigned an IP address. After the employee uses an 802.1X client on the STA for authentication and enter the correct user name and password, the STA is authenticated and can access the WLAN. The configuration method on the 802.1X client is as follows:
  - 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 employee. 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. 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.
- A guest can use a STA to find the WLAN with SSID guest. After being associated with the WLAN, the STA is assigned an IP address. When the STA accesses the Internet through a browser, the authentication page provided by the Portal server is automatically displayed. After the correct user name and password are entered on the page, the STA is authenticated and can access the WLAN. Assume that the MAC address configured on the Portal server is valid for 60 minutes. When the STA is disconnected from the WLAN for 5 minutes, the STA can access the Internet directly when reconnecting to the WLAN. When the STA is disconnected from the WLAN for 65 minutes, it will be redirected to the Portal authentication page when reconnecting to the WLAN.
