Example for Configuring MAC Address Authentication (AAA RADIUS Authentication Is Used)

Example for Configuring MAC Address Authentication (AAA RADIUS Authentication Is Used)

Networking Requirements

As shown in Figure 4-18, terminals in a company's 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 users' network access rights to ensure internal network security.

Because dumb terminals (such as printers) in the physical access control department cannot have the authentication client installed, MAC address authentication needs to be configured on the Switch. MAC addresses of terminals are used as user information and sent to the RADIUS server for authentication. When users connect to the network, authentication is not required.

Figure 4-18  Networking diagram for configuring MAC address authentication


  1. Configure AAA.

    # Create and configure the RADIUS server template rd1.

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

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

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

    # Check whether a user can pass RADIUS authentication. The test user test and password Huawei2012 have been configured on the RADIUS server.

    [Switch] test-aaa test Huawei2012 radius-template rd1
    Info: Account test succeed.

  2. Configure MAC address authentication.

    # Set the NAC mode to unified.

    By default, the unified mode is enabled. After the NAC mode is changed, the device automatically restarts.

    [Switch] authentication unified-mode

    # Configure the MAC access profile m1.


    In a MAC access profile, a MAC address without hyphens (-) is used as the user name and password for MAC address authentication. Ensure that the formats of the user name and password for MAC address authentication configured on the RADIUS server are the same as those configured on the access device.

    [Switch] mac-access-profile name m1
    [Switch-mac-access-profile-m1] quit

    # Configure the authentication profile p1, bind the MAC access profile m1 to the authentication profile, specify the domain as the forcible authentication domain in the authentication profile, set the user access mode to multi-authen, and set the maximum number of access users to 100.

    [Switch] authentication-profile name p1
    [Switch-authen-profile-p1] mac-access-profile m1
    [Switch-authen-profile-p1] access-domain force
    [Switch-authen-profile-p1] authentication mode multi-authen max-user 100
    [Switch-authen-profile-p1] quit

    # Bind the authentication profile p1 to GE1/0/1 and enable MAC address authentication on the interface.

    [Switch] interface gigabitethernet 1/0/1
    [Switch-GigabitEthernet1/0/1] authentication-profile p1
    [Switch-GigabitEthernet1/0/1] quit

    # (Recommended) Configure the source IP address and source MAC address for offline detection packets in a specified VLAN. You are advised to set the user gateway IP address and its corresponding MAC address as the source IP address and source MAC address of offline detection packets.

    [Switch] access-user arp-detect vlan 10 ip-address mac-address 2222-1111-1234

  3. Verify the configuration.

    1. After a user starts a terminal, the device automatically obtains the user terminal's MAC address as the user name and password for authentication.
    2. Users can access the network after being authenticated successfully.
    3. After users go online, you can run the display access-user access-type mac-authen command on the device to view information about online MAC address authentication users.
