RADIUS Operation
When a user attempts to log in and authenticate to a Switch that is access controlled by a RADIUS server,
these events occur:
1
The user is prompted to enter a username and password.
2
The username and encrypted password are sent over the network to the RADIUS server.
3
The user receives one of the following responses from the RADIUS server:
• ACCEPT—The user is authenticated.
• REJECT—The user is either not authenticated and is prompted to re-enter the username and password,
or access is denied.
• CHALLENGE—A challenge requires additional data from the user.
• CHALLENGE PASSWORD—A response requests the user to select a new password.
The ACCEPT or REJECT response is bundled with additional data that is used for privileged EXEC or
network authorization. The additional data included with the ACCEPT or REJECT packets includes these
items:
•
Telnet, SSH, rlogin, or privileged EXEC services
•
Connection parameters, including the host or client IP address, access list, and user timeouts
