   [Router] ip route-static 10.23.101.0 24 10.23.104.1
   

2. Configure the AC and SwitchB to function as DHCP servers to assign IP addresses to APs and STAs respectively.
   # On the AC, configure the VLANIF 100 to assign IP addresses to APs.

   [AC] dhcp enable
   [AC] interface vlanif 100
   [AC-Vlanif100] ip address 10.23.100.1 24
   [AC-Vlanif100] dhcp select interface
   [AC-Vlanif100] quit

   # 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

3. Configure APs to go online.

   # Create an AP group to which the APs with the same configuration can be added.

   [AC] wlan
   [AC-wlan-view] ap-group name ap-group1
   [AC-wlan-ap-group-ap-group1] quit
   

   # Create a regulatory domain profile, configure the AC country code in the profile, and bind the profile to the AP group.

   [AC-wlan-view] regulatory-domain-profile name default
   [AC-wlan-regulate-domain-default] country-code cn
   [AC-wlan-regulate-domain-default] quit
   [AC-wlan-view] ap-group name ap-group1
   [AC-wlan-ap-group-ap-group1] regulatory-domain-profile default
   Warning: Modifying the country code will clear channel, power and antenna gain configurations of the radio and reset the AP. Continu
   e?[Y/N]:y 
   [AC-wlan-ap-group-ap-group1] quit
   [AC-wlan-view] quit
   

   # Configure the AC's source interface.

   [AC] capwap source interface vlanif 100
   

   # Import the APs offline to the AC and add the APs to the AP group ap-group1. Configure names for the APs based on the AP locations, so that you can know where the APs are located. For example, if the AP with MAC address 60de-4476-e360 is deployed in area 1, name the AP area_1.

    NOTE:

   The default AP authentication mode is MAC address authentication. If the default settings are retained, you do not need to run the ap auth-mode mac-auth command.

   In this example, the AP5030DN is used and has two radios: radio 0 and radio 1. Radio 0 and radio 1 operate on the 2.4 GHz and 5 GHz bands respectively.

   [AC] wlan
   [AC-wlan-view] ap auth-mode mac-auth
   [AC-wlan-view] ap-id 0 ap-mac 60de-4476-e360
   [AC-wlan-ap-0] ap-name area_1
   [AC-wlan-ap-0] ap-group ap-group1
   Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configuration

   2. Configure an 802.1x access profile to manage 802.1x access control parameters.

      # Create the 802.1x access profile wlan-net.

      [AC] dot1x-access-profile name wlan-net
      

      # Configure EAP relay authentication.

      [AC-dot1x-access-profile-wlan-net] dot1x authentication-method eap
      [AC-dot1x-access-profile-wlan-net] quit
      

   3. Create the authentication profile wlan-net and bind it to the 802.1x access profile, authentication scheme, and RADIUS server template.

      [AC] authentication-profile name wlan-net
      [AC-authentication-profile-wlan-net] dot1x-access-profile wlan-net
      [AC-authentication-profile-wlan-net] authentication-scheme wlan-net
      [AC-authentication-profile-wlan-net] radius-server wlan-net
      [AC-authentication-profile-wlan-net] quit

   4. Configure WLAN service parameters.

      # Create the security profile wlan-net and set the security policy in the profile.

      [AC] wlan
      [AC-wlan-view] security-profile name wlan-net
      [AC-wlan-sec-prof-wlan-net] security wpa-wpa2 dot1x aes
      [AC-wlan-sec-prof-wlan-net] quit
      

      # Create the SSID profile wlan-net and set the SSID name to wlan-net.

      [AC-wlan-vap-prof-wlan-net] forward-mode direct-forward
      [AC-wlan-vap-prof-wlan-net] service-vlan vlan-id 101
      [AC-wlan-vap-prof-wlan-net] security-profile wlan-net
      [AC-wlan-vap-prof-wlan-net] authentication-profile wlan-net
      [AC-wlan-vap-prof-wlan-net] ssid-profile wlan-net
      [AC-wlan-vap-prof-wlan-net] quit
      

      # Bind the VAP profile wlan-net to the AP group and apply the profile to radio 0 and radio 1 of the AP.

      [AC-wlan-view] ap-group name ap-group1
      [AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 0
      [AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 1
      [AC-wlan-ap-group-ap-group1] quit
      [AC-wlan-view] quit
      

6. Configure the Cisco ISE.
   1. # Log in to the Cisco ISE server.

      # Enter the access address of the Cisco ISE server in the address box, which is in the format of https://Cisco ISE IP. Cisco ISE IP is the IP address of the Cisco ISE server.

      # On the displayed page, enter the user name and password to log in to the Cisco ISE server.

   2. Create a department and an account.

      # Choose Administration > Identity Management > Groups > User Identity Groups. In the pane on the right side, click Add and create a department named R&D. Then, click Submit.

      
      
      

      # Choose Administration > Identity Management > Identities > Users. In the pane on the right side, click Add to create the account with the user name of huawei and password of huawei123. Add the account to department R&D. Then, click Submit.

      
      
      

   3. Add the AC so that the Cisco ISE can interwork with the AC.

      # Choose Administration > Network Resources > Network Device Profiles. In the pane on the left side, click Add and create a device profile named Huawei. Then, click Submit.

      
      
      

      # Choose Administration > Network Resources > Network Devices. In the pane on the right side, click Add. Set the device name to AC6605, IP address to 10.23.102.2/32, and RADIUS shared key to huawei@123. Then, click Submit.

      
      
      

   4. Configure the authentication protocol.

      # Choose Policy > Policy Elements > Results > Authentication > Allowed Protocols. Select Default Network Access and click Edit.

      
      
      
      # Select Allow CHAP, Allow MS-CHAPv2, and Allow PEAP. For other parameters, use the default settings. Click Save.

       NOTE:

      By default, the Cisco ISE disables the CHAP authentication protocol. You need to select the CHAP authentication protocol on the server so that the CHAP protocol can be used to carry out the test-aaa test on the AC.

      
      
      

7. On the AC, check whether users can pass RADIUS authentication.

   Info: Account test succeed.
   

8. 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 XP operating system:

       1. On the Association tab page of the Wireless network properties dialog box, add SSID wlan-net, set the authentication mode to WPA2, and encryption algorithm to AES.
       2. On the Authentication tab page, set EAP type to PEAP and click Properties. 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.

     • 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.
