Example of a Failed Authentication
To view the configuration, use the
show config
in LINE mode or the
show running-config
command in EXEC Privilege
mode.
If authentication fails using the primary method, Dell Networking OS employs the second method (or third method, if necessary)
automatically. The fallback to the second method would happen only if the authentication failure is due to a non-reachable server or invalid
TACACS server key. The fallback would not occur if the authentication failure is due to invalid credentials. For example, if the
server is reachable, but the server key is invalid, Dell Networking OS proceeds to the next authentication method. In the following example,
the is incorrect, but the user is still authenticated by the secondary method.
First bold line: Server key purposely changed to incorrect value.
Second bold line: User authenticated using the secondary method.

Remote Authentication
The system takes the access class from the server. Access class is the class of service that restricts Telnet access and packet
sizes.
If you have configured remote authorization, the system ignores the access class you have configured for the VTY line and gets this access
class information from the server. The system must know the username and password of the incoming user before it can fetch
