MAC Authentication Configuration Example
Network requirements
As illustrated in Figure 1-1, a supplicant is connected to the switch through port Ethernet 1/0/2.
z MAC authentication is required on port Ethernet 1/0/2 to control user access to the Internet.
z All users belong to domain aabbcc.net. The authentication performed is locally and the MAC
address of the PC (00-0d-88-f6-44-c1) is used as both the user name and password.

# Enable MAC authentication on port Ethernet 1/0/2.
<Sysname> system-view
[Sysname] mac-authentication interface Ethernet 1/0/2
# Set the user name in MAC address mode for MAC authentication, requiring hyphened lowercase
MAC addresses as the usernames and passwords.
[Sysname] mac-authentication authmode usernameasmacaddress usernameformat with-hyphen
lowercase
# Add a local user.
z Specify the user name and password.
[Sysname] local-user 00-0d-88-f6-44-c1
[Sysname-luser-00-0d-88-f6-44-c1] password simple 00-0d-88-f6-44-c1
z Set the service type to “lan-access”.
[Sysname-luser-00-0d-88-f6-44-c1] service-type lan-access
[Sysname-luser-00-0d-88-f6-44-c1] quit
# Add an ISP domain named aabbcc.net.
[Sysname] domain aabbcc.net
New Domain added.
# Specify to perform local authentication.
[Sysname-isp-aabbcc.net] scheme local
[Sysname-isp-aabbcc.net] quit
# Specify aabbcc.net as the ISP domain for MAC authentication
[Sysname] mac-authentication domain aabbcc.net
# Enable MAC authentication globally (This is usually the last step in configuring access control related
features. Otherwise, a user may be denied of access to the networks because of incomplete
configuaration.)
