Usage Guidelines
MAC authentication profile configures authentication of devices based on their physical MAC address. MAC-based
authentication is often used to authenticate and allow network access through certain devices while denying access
to all other devices. Users may be required to authenticate themselves using other methods, depending upon the
network privileges.
Example
The following example configures a MAC authentication profile to blacklist client devices that fail to authenticate.
