Users Guide

Methods configured with the aaa authentication enable command are evaluated in the order
they are configured. If authentication fails using the primary method, the system employs the second
method (or third method, if necessary) automatically. For example, if the TACACS+ server is reachable,
but the server key is invalid, the system proceeds to the next authentication method. The TACACS+ is
incorrect, but the user is still authenticated by the secondary method.
