DGS-3312SR Layer 3 Gigabit Switch config authen_enable Description Parameters This command is used to promote users with normal level privileges to Administrator 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. 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 a "Admin" privilege. default - The default method list for administration rights authentication, as defined by the user. The user may choose one or a combination of up to four (4) of the following authentication methods: tacacs - Adding this parameter will require the user to be authenticated using the TACACS protocol from the remote TACACS server hosts of the TACACS server group list. xtacacs - Adding this parameter will require the user to be authenticated using the XTACACS protocol from the remote XTACACS server hosts of the XTACACS server group list. tacacs+ - Adding this parameter will require the user to be authenticated using the TACACS+ protocol from the remote TACACS+ server hosts of the TACACS+ server group list. radius - Adding this parameter will require the user to be authenticated using the RADIUS protocol from the remote RADIUS server hosts of the RADIUS server group list. server_group - Adding this parameter will require the user to be authenticated using a user-defined server group previously configured on the switch. local_enable - 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. method_list_name - Enter a previously implemented method list name defined by the user (create authen_enable). 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 146
