Example for Configuring 802.1X Authentication to Control User Access

802.1X Authentication Overview

802.1X is a port-based network access control protocol and 802.1X authentication is one of NAC authentication modes. 802.1X authentication ensures security of enterprise intranets.

802.1X authentication ensures high security; however, it requires that 802.1X client software be installed on user terminals, resulting in inflexible network deployment. Another two NAC authentication methods have their advantages and disadvantages: MAC address authentication does not require client software installation, but MAC addresses must be registered on an authentication server. Portal authentication also does not require client software installation and provides flexible deployment, but it has low security.

As a result, 802.1X authentication is applied to scenarios with new networks, centralized user distribution, and strict information security requirements. In addition, 802.1X authentication supports MAC address bypass authentication so that the dumb terminals on 802.1X authentication networks can be connected after passing authentication.

Configuration Notes

This configuration example applies to all switches running all versions.

Networking Requirements

As shown in Figure 3-232, the terminals in an office are connected to the company's internal network through the Switch. Unauthorized access to the internal network can damage the company's service system and cause leakage of key information. Therefore, the administrator requires that the Switch should control the users' network access rights to ensure internal network security.

Figure 3-232 Networking diagram for configuring 802.1X authentication

Configuration Roadmap

The configuration roadmap is as follows:

  1. Create and configure a RADIUS server template, an AAA scheme, and an authentication domain. Bind the RADIUS server template and AAA scheme to the authentication domain so that the Switch can authenticate access users through the RADIUS server.
  2. Configure 802.1X authentication on the Switch.
    1. Enable 802.1X authentication to control network access rights of the employees in the office.
    2. Enable MAC address bypass authentication to authenticate terminals (such as printers) that cannot install 802.1X authentication client software.
    • Before configuring this example, ensure that devices can communicate with each other in the network.
    • In this example, the LAN switch exists between the access switch Switch and users. To ensure that users can pass 802.1X authentication, you must configure the EAP packet transparent transmission function on the LAN switch.
      • Method 1: The S5700-LI is used as an example of the LAN switch. Perform the following operations:
        1. Run the l2protocol-tunnel user-defined-protocol 802.1x protocol-mac 0180-c200-0003 group-mac 0100-0000-0002 command in the system view of the LAN switch to configure the LAN switch to transparently transmit EAP packets.
        2. Run the l2protocol-tunnel user-defined-protocol 802.1x enable command on the interface connecting to users and the interface connecting to the access switch to enable the Layer 2 protocol tunneling function.
      • Method 2: This method is recommended when a large number of users exist or high network performance is required. Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5731-S, S5731S-S, S6720-EI, S6720-HI, S6720S-EI, S5732-H, S6730-H, S6730S-H, S6730-S, and S6730S-S support this method.
        1. Run the following commands in the system view:
          • undo bpdu mac-address 0180-c200-0000 ffff-ffff-fff0
          • bpdu mac-address 0180-c200-0000 FFFF-FFFF-FFFE
          • bpdu mac-address 0180-c200-0002 FFFF-FFFF-FFFF
          • bpdu mac-address 0180-c200-0004 FFFF-FFFF-FFFC
          • bpdu mac-address 0180-c200-0008 FFFF-FFFF-FFF8
        2. (This step is mandatory when you switch from method 1 to method 2.) Run the undo l2protocol-tunnel user-defined-protocol 802.1x enable command in the interface view to delete the configuration of transparent transmission of 802.1x protocol packets.

Procedure

  1. Create VLANs and configure the VLAN allowed by the interface to ensure network communication.

    # Create VLAN 10 and VLAN 20.

    <HUAWEI> system-view
[HUAWEI] sysname Switch
[Switch] vlan batch 10 20

    # On the Switch, set GE1/0/1 connecting to users as an access interface, and add GE1/0/1 to VLAN 10.

    [Switch] interface gigabitethernet1/0/1
[Switch-GigabitEthernet1/0/1] port link-type access
[Switch-GigabitEthernet1/0/1] port default vlan 10 
[Switch-GigabitEthernet1/0/1] quit

    Configure the interface type and VLANs according to the actual situation. In this example, users are added to VLAN 10.

    # On the Switch, set GE1/0/2 connecting to the RADIUS server as an access interface, and add GE1/0/2 to VLAN 20.

    [Switch] interface gigabitethernet1/0/2
[Switch-GigabitEthernet1/0/2] port link-type access
[Switch-GigabitEthernet1/0/2] port default vlan 20
[Switch-GigabitEthernet1/0/2] quit

  2. Create and configure a RADIUS server template, an AAA scheme, and an authentication domain.

    # Create and configure the RADIUS server template rd1.

    [Switch] radius-server template rd1
[Switch-radius-rd1] radius-server authentication 192.168.2.30 1812
[Switch-radius-rd1] radius-server shared-key cipher Huawei@2012
[Switch-radius-rd1] quit

    # Create AAA scheme abc and set the authentication mode to RADIUS.

    [Switch] aaa
[Switch-aaa] authentication-scheme abc
[Switch-aaa-authen-abc] authentication-mode radius
[Switch-aaa-authen-abc] quit

    # Create authentication domain isp1, and bind AAA scheme abc and RADIUS server template rd1 to authentication domain isp1.

    [Switch-aaa] domain isp1
[Switch-aaa-domain-isp1] authentication-scheme abc
[Switch-aaa-domain-isp1] radius-server rd1
[Switch-aaa-domain-isp1] quit
[Switch-aaa] quit

    # Configure the default domain isp1 in the system view. When a user enters the user name in the format of user@isp1, the user is authenticated in the authentication domain isp1. If the user name does not carry the domain name or carries a nonexistent domain name, the user is authenticated in the default domain.

    [Switch] domain isp1

  3. Configure 802.1X authentication.

    # Switch the NAC mode to common mode. This step applies to only switches in V200R005C00 and later versions.

    [Switch] undo authentication unified-mode
Warning: Switching the authentication mode will take effect after system restart
. Some configurations are invalid after the mode is switched. For the invalid co
mmands, see the user manual. Save the configuration file and reboot now? [Y/N] y
    • By default, the NAC unified mode is used.
    • After the unified mode is switched to common mode, you must save the configuration and restart the device to make each function in the new configuration mode take effect. In versions earlier than V200R007C00, you need to manually run the commands for saving the configuration and restarting the device.

    # Enable 802.1X authentication globally and on an interface.

    <Switch> system-view
[Switch] dot1x enable
[Switch] interface gigabitethernet1/0/1
[Switch-GigabitEthernet1/0/1] dot1x enable
[Switch-GigabitEthernet1/0/1] dot1x authentication-method eap

    # Configure MAC address bypass authentication.

    [Switch-GigabitEthernet1/0/1] dot1x mac-bypass

  4. Verify the configuration.

    1. Run the display dot1x command to check the 802.1X authentication configuration. The command output (802.1x protocol is Enabled) shows that the 802.1X authentication has been enabled on the interface GE1/0/1.
    2. The user starts the 802.1X client on the terminal, and enters the user name and password for authentication.
    3. If the user name and password are correct, an authentication success message is displayed on the client page. The user can access the network.
    4. After the user goes online, you can run the display access-user command on the device to check the online 802.1X user information.

Example for Configuring MAC Address Authentication to Control User Access

MAC Address Authentication Overview

As one of NAC authentication modes, MAC address authentication controls a user's network access rights based on the user's interface and MAC address. The user does not need to install any client software. MAC address authentication ensures security of enterprise intranets.

In MAC address authentication, client software does not need to be installed on user terminals, but MAC addresses must be registered on servers, resulting in complex management. Another two NAC authentication methods have their advantages and disadvantages: 802.1X authentication ensures high security, but it requires that 802.1X client software be installed on user terminals, causing inflexible network deployment. Portal authentication also does not require client software installation and provides flexible deployment, but it has low security.

MAC address authentication is applied to access authentication scenarios of dumb terminals such as printers and fax machines.

Configuration Notes

This configuration example applies to all switches running all versions.

Networking Requirements

As shown in Figure 3-233, the terminals in the physical access control department are connected to the company's internal network through the Switch. Unauthorized access to the internal network can damage the company's service system and cause leakage of key information. Therefore, the administrator requires that the Switch should control the users' network access rights to ensure internal network security.

Example for Configuring Portal Authentication to Control User Access

Portal Authentication Overview

As one of NAC authentication modes, Portal authentication is also called web authentication. Generally, Portal authentication websites are also called Portal websites. When users go online, they must be authenticated on Portal websites. The users can use network resources only after they pass the authentication.

Portal authentication cannot ensure high security, but it does not require client software installation and provides flexible deployment. Another two NAC authentication methods have their advantages and disadvantages: 802.1X authentication ensures high security, but it requires that 802.1X client software be installed on user terminals, causing inflexible network deployment. MAC address authentication does not require client software installation, but MAC addresses must be registered on an authentication server, resulting in complex management.

Portal authentication is applied to scenarios where a large number of scattered users such as company visitors move frequently.

This example applies to the following products:
  • V200R005C00SPC300 and later versions: S2750-EI, S5700-LI, S5700S-LI
  • S2720-EI, S3700-SI, S3700-EI, S3700-HI

Configuration Roadmap

The configuration roadmap is as follows:

  1. Create and configure a RADIUS server template, an AAA scheme, and an authentication domain. Bind the RADIUS server template and AAA scheme to the authentication domain so that the Switch can authenticate access users through the RADIUS server.
  2. Configure Portal authentication so that the device can control network access rights of the visitors in the visitor areas.
    1. Create and configure a Portal server template to ensure normal information exchange between the device and the Portal server.
    2. Enable Portal authentication to authenticate access users.
    3. Configure a shared key that the device uses to exchange information with the Portal server to improve communication security.

Before configuring this example, ensure that devices can communicate with each other in the network.

Procedure

  1. Create VLANs and configure the VLAN allowed by the interface to ensure network communication.

    # Create VLAN 10 and VLAN 20.

    <HUAWEI> system-view
[HUAWEI] sysname Switch
[Switch] vlan batch 10 20

    # On the Switch, set GE1/0/1 connecting to users as an access interface, and add GE1/0/1 to VLAN 10.

[Switch-GigabitEthernet1/0/1] port link-type access
[Switch-GigabitEthernet1/0/1] port default vlan 10 
[Switch-GigabitEthernet1/0/1] quit

    Configure the interface type and VLANs according to the actual situation. In this example, users are added to VLAN 10.

    # On the Switch, set GE1/0/2 connecting to the RADIUS server as an access interface, and add GE1/0/2 to VLAN 20.

    [Switch] interface gigabitethernet1/0/2
[Switch-GigabitEthernet1/0/2] port link-type access
[Switch-GigabitEthernet1/0/2] port default vlan 20
[Switch-GigabitEthernet1/0/2] quit

  2. Create and configure a RADIUS server template, an AAA scheme, and an authentication domain.

    # Create and configure the RADIUS server template rd1.

    [Switch] radius-server template rd1

    [Switch] undo authentication unified-mode
Warning: Switching the authentication mode will take effect after system restart
. Some configurations are invalid after the mode is switched. For the invalid co
mmands, see the user manual. Save the configuration file and reboot now? [Y/N] y
    • By default, the NAC unified mode is used.
    • After the unified mode is switched to common mode, you must save the configuration and restart the device to make each function in the new configuration mode take effect. In versions earlier than V200R007C00, you need to manually run the commands for saving the configuration and restarting the device.

    # Create and configure a Portal server template abc.

    <Switch> system-view
[Switch] web-auth-server abc
[Switch-web-auth-server-abc] server-ip 192.168.2.20
[Switch-web-auth-server-abc] port 50200
[Switch-web-auth-server-abc] url http://192.168.2.20:8080/webagent
[Switch-web-auth-server-abc] quit

    Ensure that the port number configured on the device is the same as that used by the Portal server.

    # Enable Portal authentication.

    [Switch] interface vlanif 10 
[Switch-Vlanif10] web-auth-server abc direct
[Switch-Vlanif10] quit

    # Set the shared key in cipher text to YsHsjx_202206.

    [Switch] web-auth-server abc
[Switch-web-auth-server-abc] shared-key cipher YsHsjx_202206
[Switch-web-auth-server-abc] quit

    In this example, users are allocated static IP addresses. If the users obtain IP addresses through DHCP and the DHCP server is upstream connected to Switch, use the portal free-rule command to create authentication-free rules and ensure that the DHCP server is included in the authentication-free rules.

    In versions earlier than V200R012C00, if the URL of Portal server needs to be analyzed by DNS and the DNS server is on the upstream network of the NAS device, you also need to create authentication-free rules and ensure that the DNS server is included in the authentication-free rules. In V200R012C00 and later versions, the NAS device automatically allows DNS packets to pass through and no authentication-free rule is required in Portal authentication.

  4. Verify the configuration.

    1. Run the display portal and display web-auth-server configuration commands to check the Portal authentication configuration. The command output (web-auth-server layer2(direct)) shows that the Portal server template has been bound to the interface vlanif10.
    2. After starting the browser and entering any network address, the user is redirected to the Portal authentication page. The user then enters the user name and password for authentication.
    3. If the user name and password are correct, an authentication success message is displayed on the Portal authentication page. The user can access the network.
    4. After the user goes online, you can run the display access-user command on the device to check the online Portal authentication user information.
