Parameter xStack DES-3500 Series Layer 2 Stackable Fast Ethernet Managed Switch User Manual 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 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 an authentication to access the Switch. Enable Method Lists The Enable Method List Settings 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. NOTE: To set the Local Enable Password, see the next section, entitled Local Enable Password. To view the following table, click Security Management > Access Authentication Control > Enable Method Lists: Figure 7- 16. Enable Method List Settings window To delete an Enable Method List defined by the user, click the X under the Delete heading corresponding to the entry desired to be deleted. To modify an Enable Method List, click on its hyperlinked Method List Name. To configure a Method List, click the Add button. Both actions will result in the same window to configure: 132
