xStack® DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch Figure 6 - 51 Login Method List - Add window To define a Login Method List, set the following parameters and click Apply: Parameter Description Method List Name Method 1, 2, 3, 4 Enter a method list name defined by the user of up to 15 characters. The user may add one, or a combination of up to four 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 userdefined 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. Click Apply to implement the changes. To return to the Login Method Lists window, click the Show All Authentication Login Method List Entries link. Enable Method Lists This 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 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. 319
