Authentication methods
You can perform MAC authentication on the access device (local authentication) or through a RADIUS server.
For more information about configuring local authentication and RADIUS authentication, see "Configuring AAA."
RADIUS authentication
If MAC-based accounts are used, the access device sends the source MAC address of the packet as the username and password to the RADIUS server for authentication.
If a shared account is used, the access device sends the shared account username and password to the RADIUS server for authentication.
Local authentication
If MAC-based accounts are used, the access device uses the source MAC address of the packet as the username and password to search the local account database for a match.
If a shared account is used, the access device uses the shared account username and password to search the local account database for a match.
