Parameter Description

Method List Name

Enter a method list name defined by the user of up to 15 characters.

Method 1, 2, 3, 4

The user may add one, or a combination of up to four (4) of the following

authentication methods to this method list:

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.

tacacs+ - Adding this parameter will require the user to be authenticated using the

TACACS+ protocol from a remote TACACS+ server.

radius - Adding this parameter will require the user to be authenticated using the

RADIUS protocol from a remote RADIUS server.

server_group - Adding this parameter will require the user to be authenticated

using a user-defined server group previously configured on the Switch.

local - Adding this parameter will require the user to be authenticated using the

local user account database on the Switch.

none - Adding this parameter will require no authentication to access the Switch.

Enable Method Lists

The Enable Method Lists window is used to 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 (8) 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.
