Configuring the macAddressElseUserLoginSecure mode
Network requirements
As shown in Figure 49, a client is connected to the Device through Ethernet 1/1. The Device authenticates
the client by a RADIUS server. If the authentication succeeds, the client is authorized to access the
Internet.
Restrict port Ethernet 1/1 of the Device:
• Allow more than one MAC authenticated user to log on.
• For 802.1X users, perform MAC authentication first and then, if MAC authentication fails, 802.1X
authentication. Allow only one 802.1X user to log on.
• Use the hyphenated, lowercased MAC address of a user as both the username and password for
MAC authentication of the user.
• Set the total number of MAC authenticated users and 802.1X authenticated users to 64.
• Enable NTK to prevent frames from being sent to unknown MAC addresses.
Configuration procedure
Configuration procedures for the host and RADIUS servers are not shown.
1. Configure the RADIUS protocol:
Configure the RADIUS authentication/accounting and ISP domain settings the same as in
"Configuring the userLoginWithOUI mode."
2. Conf
igure port security:
# Enable port security.
<Device> system-view
[Device] port-security enable
# Use MAC-based user accounts for MAC authentication users. Each MAC address must be
hyphenated and in lowercase.
[Device] mac-authentication user-name-format mac-address with-hyphen lowercase
[Device] interface ethernet 1/1
# Specify ISP domain sun for MAC authentication.
[Device] mac-authentication domain sun
# Set the 802.1X authentication method to CHAP. (This configuration is optional. By default, the
authentication method is CHAP for 802.1X.)
[Device] dot1x authentication-method chap
# Set port security's limit on the number of MAC addresses to 64 on the port.
[Device] interface ethernet 1/1
[Device-Ethernet1/1] port-security max-mac-count 64
# Set the port security mode to macAddressElseUserLoginSecure.
[Device-Ethernet1/1] port-security port-mode mac-else-userlogin-secure
# Set the NTK mode of the port to ntkonly.
[Device-Ethernet1/1] port-security ntk-mode ntkonly
Verifying the configuration
# Display the port security configuration.
<Device> display port-security interface ethernet 1/1
