Example for Configuring 802.1x Authentication (Web)

Introduction to 802.1x Authentication

802.1X authentication is a method used for Network Admission Control (NAC). It controls user access rights based on access ports to protect enterprise intranet security.

802.1X authentication is more secure than MAC address authentication and Portal authentication; however, it requires that 802.1X client software be installed on all user terminals, allowing low networking flexibility. In contrast, MAC address authentication does not need client software, but user terminals' MAC addresses must be registered on the authentication server. Network configuration and management are complex. Portal authentication also does not need client software, allowing flexible deployment. However, it does not provide high security. Therefore, 802.1X authentication is applicable to network construction scenarios where users are densely distributed and high information security is required.

When the AC is interconnected with the Cisco ISE, three authentication methods, that is, Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), and Extensible Authentication Protocol (EAP), can be used in 802.1X authentication. The configurations for the three authentication methods are similar. The following uses EAP as an example.

For details about how to configure 802.1x authentication on the AC, see Configure WLAN services.

For details about how to configure the authentication on the Cisco ISE server, see Configure the Cisco ISE.

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

  1. Configure network interworking of the AC, APs, and other network devices.
  2. Select Config Wizard to configure system parameters for the AC.
  3. Select Config Wizard to configure the APs to go online on the AC.
  4. Select Config Wizard to configure WLAN services on the AC. When configuring the security policy, select 802.1x and RADIUS authentication, and set the RADIUS server parameters.
  5. Configure the Cisco ISE server.

Configuration Notes

  • 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.

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

Procedure

  1. Configure the network devices.

  2. Configure a DHCP server to assign IP addresses to STAs.

    # On SwitchB, configure the VLANIF 101 to assign IP addresses to STAs.
    NOTE:
    Configure the DNS server as required. The common methods are as follows:
    • In interface address pool scenarios, run the dhcp server dns-list ip-address &<1-8> command in the VLANIF interface view.
    • In global address pool scenarios, run the dns-list ip-address &<1-8> command in the IP address pool view.
    [SwitchB] dhcp enable
    [SwitchB] interface vlanif 101
    [SwitchB-Vlanif101] ip address 10.23.101.1 24
    [SwitchB-Vlanif101] dhcp select interface
    [SwitchB-Vlanif101] quit
