Configuration procedure

1. Make sure the RADIUS server and the access device can reach each other.

2. Create a shared account for MAC authentication users on the RADIUS server, and set the

username aaa and password 123456 for the account.

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 2000 for authentication, authorization, and

accounting.

[Device] domain 2000

[Device-isp-2000] authentication default radius-scheme 2000

[Device-isp-2000] authorization default radius-scheme 2000

[Device-isp-2000] accounting default radius-scheme 2000

[Device-isp-2000] quit

# Enable MAC authentication globally.

[Device] mac-authentication

# Enable MAC authentication on port GigabitEthernet 1/1.

[Device] interface gigabitethernet 1/1

[Device-Gigabitethernet1/1] mac-authentication

[Device-Gigabitethernet1/1] quit

# Specify the MAC authentication domain as the ISP domain 2000.

[Device] mac-authentication domain 2000

# Set MAC authentication timers.

[Device] mac-authentication timer offline-detect 180

[Device] mac-authentication timer quiet 180
