Default Web-Based Authentication Configuration
Table 12-1 shows the default web-based authentication configuration.
Web-Based Authentication Configuration Guidelines and Restrictions
• Web-based authentication is an ingress-only feature.
• You can configure web-based authentication only on access ports. Web-based authentication is not
supported on trunk ports, EtherChannel member ports, or dynamic trunk ports.
• You must configure the default ACL on the interface before configuring web-based authentication.
Configure a port ACL for a Layer 2 interface or a Cisco IOS ACL for a Layer 3 interface.
• You cannot authenticate hosts on Layer 2 interfaces with static ARP cache assignment. These hosts
are not detected by the web-based authentication feature because they do not send ARP messages.
• By default, the IP device tracking feature is disabled on a switch. You must enable the IP device
tracking feature to use web-based authentication.
• You must configure at least one IP address to run the switch HTTP server. You must also configure
routes to reach each host IP address. The HTTP server sends the HTTP login page to the host.
