User account policies
User accounts are required for identifying clients. MAC authentication supports the following user account policies:
One MAC-based user account for each client. The authenticator uses the unknown source MAC addresses in packets as the usernames and passwords of clients for MAC authentication.
One shared user account for all clients. You specify one username and password, which are not necessarily a MAC address, for all MAC authentication clients on the authenticator. The username is a case-sensitive string of 1 to 55 characters which cannot include the at sign (@). The password can be a plaintext string of 1 to 63 characters or ciphertext string of 1 to 117 characters.
