Figure 10-13. Connecting to the Captive Portal
The CP feature blocks hosts connected to the switch from most network
access until user verification has been established. Access to 802.1X, DHCP,
ARP, NetBIOS, and DNS services is allowed. The network administrator can
configure CP verification to allow access for both guest and authenticated
users. Authenticated users must be validated against a database of authorized
CP users before access is granted. The database can be stored locally on the
switch or on a RADIUS server.
