Prerequisites for MAC authentication

Before you configure MAC authentication, complete the following tasks:

1. Make sure the port security feature is disabled. For more information about port security, see "Configuring port security."

2. Configure an ISP domain and specify an AAA method. For more information, see "Configuring AAA."

   • For local authentication, you must also create local user accounts (including usernames and passwords) and specify the lan-access service for local users.

   • For RADIUS authentication, make sure the device and the RADIUS server can reach each other and create user accounts on the RADIUS server. If you are using MAC-based accounts, make sure the username and password for each account are the same as the MAC address of each MAC authentication user.
