Version Description
6.2.1.0 Introduced on the E-Series.
Usage
Information
By default, the Enable password is used. If you configure aaa authentication enable
default, Dell Networking OS uses the methods defined for Enable access instead.
Methods configured with the aaa authentication enable command are evaluated in the order
they are configured. If authentication fails using the primary method, Dell Networking 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.
