MAC-based Authentication

This chapter describes how to configure MAC-based authentication on the Dell controller using the WebUI.

Use MAC-based authentication to authenticate devices based on their physical media access control (MAC) address. While not the most secure and scalable method, MAC-based authentication implicitly provides an addition layer of security authentication devices. MAC-based authentication is often used to authenticate and allow network access through certain devices while denying access to the rest. For example, if clients are allowed access to the network via station A, then one method of authenticating station A is MAC-based. Clients may be required to authenticate themselves using other methods depending on the network privileges required.

MAC-based authentication can also be used to authenticate Wi-Fi phones as an additional layer of security to prevent other devices from accessing the voice network using what is normally an insecure SSID.

This chapter describes the following topics:

Configuring MAC-Based Authentication

Before configuring MAC-based authentication, you must configure:

The user role that will be assigned as the default role for the MAC-based authenticated clients. (See Roles and Policies on page 296 for information on firewall policies to configure roles).

You configure the default user role for MAC-based authentication in the AAA profile. If derivation rules exist or if the client configuration in the internal database has a role assignment, these values take precedence over the default user role.

Authentication server group that the controller uses to validate the clients. The internal database can be used to configure the clients for MAC-based authentication. See "Configuring Clients" on page 190 for information on configuring the clients on the local database. For information on configuring authentication servers and server groups, see Authentication Servers on page 168

Configuring the MAC Authentication Profile

Table 58 describes the parameters you can configure for MAC-based authentication.
