802.1x Configuration Commands 349 Parameter macbased: Configures the 802.1x authentication system to perform authentication on the supplicant based on MAC address. portbased: Configures the 802.1x authentication system to perform authentication on the supplicant based on interface number. interface interface-list: Ethernet interface list including several Ethernet interfaces, expressed in the format interface-list = { interface-num [ to interface-num ] } & < 1-10 >. interface-num specifies a single Ethernet interface in the format interface-num = { interface-type interface-num | interface-name }, where interface-type specifies the interface type, interface-num specifies the interface number and interface-name specifies the interface name. For the respective meanings and value ranges, see the parameters in the Port Command chapter. Description Use the dot1x port-method command to configure the base for 802.1x to perform access control on the specified interface. Use the undo dot1x port-method command to restore the default access control base. By default, the value is macbased. This command is used to set the base for 802.1x to perform access control, namely authenticate the users, on the specified interface. When macbased is used, the users accessing this interface must be authenticated independently, and as such will be able to access the network as long as they independently require. When portbased is used, only the first user on that port needs to be authenticated. Subsequent users accessing the network through this port are considered authenticated. However if the original user terminates his connection, the other users will need to be re-authenicated. This command has an effect on the interface specified by the parameter interface-list when executed in System View. It has an effect on all the interfaces when no interface is specified. The parameter interface-list cannot be input when the command is executed in Ethernet Port View and it has an effect only on the current interface. Related command: display dot1x. Example To authenticate the supplicant based on the interface number on Gigabitethernet 1/0/1, enter the following: system-view System View: return to User View with Ctrl-Z [SW5500]dot1x port-method portbased interface gigabitethernet 1/0/1 dot1x quiet-period Command dot1x quiet-period undo dot1x quiet-period
