Enable Method Lists
Users can set up Method Lists to promote users with user level privileges to Administrator (Admin) level privileges using
authentication methods on the Switch. Once a user acquires normal user level privileges on the Switch, he or she must be
authenticated by a method on the Switch to gain administrator privileges on the Switch, which is defined by the Administrator. A
maximum of eight Enable Method Lists can be implemented on the Switch, one of which is a default Enable Method List. This
default Enable Method List cannot be deleted but can be configured.
The sequence of methods implemented in this command will affect the authentication result. For example, if a user enters a
sequence of methods like TACACS - XTACACS - Local Enable, the Switch will send an authentication request to the first
TACACS host in the server group. If no verification is found, 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 Enable
password set in the Switch is used to authenticate the user.
Successful authentication using any of these methods will give the user an "Admin" privilege.
NOTE: To set the Local Enable Password, see the next section, entitled Local Enable Password.

The user may add one, or a combination of up to four of the following authentication methods
to this method list:
local_enable - Adding this parameter will require the user to be authenticated using the local
enable password database on the Switch. The local enable password must be set by the user
in the next section entitled Local Enable Password.
none - Adding this parameter will require no authentication to access the Switch.
radius - Adding this parameter will require the user to be authenticated using the RADIUS
protocol from a remote RADIUS server.
tacacs - Adding this parameter will require the user to be authenticated using the TACACS
protocol from a remote TACACS server.
xtacacs - Adding this parameter will require the user to be authenticated using the XTACACS
protocol from a remote XTACACS server.
- Adding this parameter will require the user to be authenticated using the TACACS
protocol from a remote TACACS server.
