NOTE: More than one authentication protocol can be run on the same physical server host but,
remember that TACACS/XTACACS/TACACS+ are separate entities and are not compatible
with each other.
Login Method Lists Settings
User-defined or default Login Method List of authentication techniques can be configured for users logging on to
the Switch. The sequence of techniques implemented in this command will affect the authentication result. For
example, if a user enters a sequence of techniques, for example TACACS - XTACACS- local, the Switch will send
an authentication request to the first TACACS host in the server group. If no response comes from the server host,
the Switch will send an authentication request to the second TACACS host in the server group and so on, until the
list is exhausted. At that point, the Switch will restart the same sequence with the following protocol listed,
XTACACS. If no authentication takes place using the XTACACS list, the local account database set in the Switch is
used to authenticate the user. When the local method is used, the privilege level will be dependent on the local
account privilege configured on the Switch.
Successful login using any of these techniques will give the user a "User" privilege only. If the user wishes to
upgrade his or her status to the administrator level, the user must use the Enable Admin window, in which the user
must enter a previously configured password, set by the administrator.
