RADIUS-based MAC authentication configuration example

As shown in Figure 47, the device uses RADIUS servers to perform authentication, authorization, and accounting for users.

To control user access to the Internet by MAC authentication, perform the following tasks:

• Enable MAC authentication globally and on GigabitEthernet 1/0/1.

• Configure the device to detect whether a user has gone offline every 180 seconds.

• Configure the device to deny a user for 180 seconds if the user fails MAC authentication.

• Configure all users to belong to ISP domain bbb.

• Use a shared user account for all users, with username aaa and password 123456.

1. Make sure the RADIUS server and the access device can reach each other. (Details not shown.)

2. Configure the RADIUS servers:

   # Create a shared account for MAC authentication users. (Details not shown.)

   # Set username aaa and password 123456 for the account. (Details not shown.)

3. Configure RADIUS-based MAC authentication on the device:

   # Configure a RADIUS scheme.

   <Device> system-view
   [Device] radius scheme 2000
   [Device-radius-2000] primary authentication 10.1.1.1 1812
   [Device-radius-2000] primary accounting 10.1.1.2 1813
   [Device-radius-2000] key authentication simple abc
   [Device-radius-2000] key accounting simple abc
   [Device-radius-2000] user-name-format without-domain
   [Device-radius-2000] quit
   

   # Apply the RADIUS scheme to ISP domain bbb for authentication, authorization, and accounting.

   [Device] domain bbb
   [Device-isp-bbb] authentication default radius-scheme 2000
   [Device-isp-bbb] authorization default radius-scheme 2000
   [Device-isp-bbb] accounting default radius-scheme 2000
   [Device-isp-bbb] quit
   

   # Enable MAC authentication on GigabitEthernet 1/0/1.

   [Device] interface gigabitethernet 1/0/1
   [Device-GigabitEthernet1/0/1] mac-authentication
   [Device-GigabitEthernet1/0/1] quit
   

   # Specify the MAC authentication domain as ISP domain bbb.

   [Device] mac-authentication domain bbb
   

   # Set MAC authentication timers.

   [Device] mac-authentication timer offline-detect 180
   [Device] mac-authentication timer quiet 180
   

   # Specify username aaa and password 123456 in plain text for the account shared by MAC authentication users.

   [Device] mac-authentication user-name-format fixed account aaa password simple 123456
   

   # Enable MAC authentication globally.

   [Device] mac-authentication
   

# Verify the MAC authentication configuration.
