Example: Configuring port security in macAddressElseUserLoginSecure mode
Network configuration
As shown in Figure 96, a client is connected to the device through HundredGigE 1/0/1. The device authenticates the client by a RADIUS server in ISP domain sun. If the authentication succeeds, the client is authorized to access the Internet.
Configure HundredGigE 1/0/1 of the device to meet the following requirements:
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 MAC address of each user as the username and password for authentication. A MAC address is in the hexadecimal notation with hyphens, and letters are in upper case.
Set the total number of MAC authenticated users and 802.1X authenticated users to 64.
Enable NTK (ntkonly mode) to prevent frames from being sent to unknown MAC addresses.

Procedure
Make sure the host and the RADIUS server can reach each other.
Configure RADIUS authentication/accounting and ISP domain settings. (See "Example: Configuring port security in userLoginWithOUI mode.")
Configure port security:
# Enable port security.
<Device> system-view [Device] port-security enable
# Use MAC-based accounts for MAC authentication. Each MAC address must be in the hexadecimal notation with hyphens, and letters are in upper case.
[Device] mac-authentication user-name-format mac-address with-hyphen uppercase
# Specify the MAC authentication domain.
[Device] mac-authentication domain sun
# Set the 802.1X authentication method to CHAP. By default, the authentication method for 802.1X is CHAP.
[Device] dot1x authentication-method chap
# Set port security's limit on the number of MAC addresses to 64 on the port.
[Device] interface hundredgige 1/0/1 [Device-HundredGigE1/0/1] port-security max-mac-count 64
# Set the port security mode to macAddressElseUserLoginSecure.
[Device-HundredGigE1/0/1] port-security port-mode mac-else-userlogin-secure
# Specify ISP domain sun as the mandatory authentication domain for 802.1X users.
[Device-HundredGigE1/0/1] dot1x mandatory-domain sun
# Set the NTK mode of the port to ntkonly.
[Device-HundredGigE1/0/1] port-security ntk-mode ntkonly [Device-HundredGigE1/0/1] quit
Verifying the configuration
# Verify the port security configuration.
