What Other Features Use Authentication? In addition to controlling access to the management interface, the switch can use RADIUS, IAS, or the local user database to provide port-based access control. Port-based access control specifies whether devices that are connected to the switch ports are allowed access to the network. The IEEE 802.1X feature (also known as Dot1X) and Captive Portal feature use RADIUS or the local user database to control network access. IEEE 802.1X can also use the IAS to authenticate users. For information about IEEE 802.1X, see "Configuring 802.1X and Port-Based Security" on page 509. For information about Captive Portal, see "Configuring a Captive Portal" on page 453. The RADIUS server can provide VLAN assignments to devices connected to the switch ports. For information about RADIUS-assigned VLANs, see "Dynamic VLAN Creation" on page 514. Default Management Security Values By default, the only management access to the switch is through the console port, and no authentication is required. Table 9-2 describes the default settings for the management access features. Table 9-2.
