Displaying and Debugging Centralized MAC Address Authentication 237n ■ If the MAC address regular re-authentication function is enabled, when theReauth-period times out, the device initiates a re-authentication.■ When you configure to re-authenticate a user with the specified MAC address,each MAC address re-authentication configuration on the user will trigger are-authentication. If re-authentication succeeds, the user will be authorized;otherwise, the user will be made offline.■ When you configure to re-authenticate a specified MAC address, if the MACaddress has failed the MAC address authentication, the re-authenticationoperation will be ignored.Displaying andDebuggingCentralized MACAddressAuthenticationAfter the above configuration, you can execute the display command in any viewto display system running of centralized MAC address authenticationconfiguration, and to verify the effect of the configuration. You can execute thereset command in user view to clear the statistics of centralized MAC addressauthentication.Centralized MACAddressAuthenticationConfigurationExamplen Centralized MAC address authentication configuration is similar to that of 802.1x.In this example, the differences between the two lie in■ Centralized MAC address authentication needs to be enabled both globally andfor a port.■ In MAC address mode, MAC address of locally authenticated user is used asboth user name and password.Table 168 Configure the centralized MAC address re-authentication functionOperation Command DescriptionEnter system view system-view -Enable the MAC addressregular re-authenticationfunctionmac-authenticationre-authenticate enableOptionalBy default, the MAC addressregular re-authenticationfunction is disabled.Configure to re-authenticatea specified MAC addressmac-authenticationre-authenticatemac-address mac-addressOptionalTable 169 Display and debug centralized MAC address authenticationOperation Command DescriptionDisplay global or portinformation about centralizedMAC address authenticationdisplay mac-authentication[ interface interface-list ]This command can beexecuted in any view.Clear the statistics of global orport centralized MAC addressauthenticationreset mac-authenticationstatistics [ interfaceinterface-list ]This command is executed inuser view
