Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.
9.3(0.0) Supported on the M I/O Aggregator.
Usage Information
By default, the Enable password is used. If you congure aaa authentication enable default, Dell
Networking Operating System (OS) uses the methods dened for Enable access instead.
Methods congured with the aaa authentication enable command are evaluated in the order they are
congured. If authentication fails using the primary method, Dell Networking Operating System (OS) employs the
second method (or third method, if necessary) automatically. For example, if the TACACS+ server is reachable, but
the server key is invalid, Dell Networking OS proceeds to the next authentication method. The TACACS+ is
incorrect, but the user is still authenticated by the secondary method.
