Using MAC Addresses to Exempt Traffic from
Authentication and Authorization
The ASA can exempt from authentication and authorization any traffic from specific MAC addresses.
For example, if the ASA authenticates TCP traffic originating on a particular network, but you want to
allow unauthenticated TCP connections from a specific server, you would use a MAC exempt rule to
exempt from authentication and authorization any traffic from the server specified by the rule.
This feature is particularly useful to exempt devices such as IP phones that cannot respond to
authentication prompts.
