zThe Web server is configured properly.

zThe default gateway of the PC is configured as the IP address of the Layer-3 virtual interface of the VLAN to which the port that is directly connected with the PC belongs.

# Configure the URL for HTTP redirection.

<device> system-view

[device] dot1x url http://192.168.0.111

# Configure a free IP range.

[device] dot1x free-ip 192.168.0.111 24

Troubleshooting

If a user enters an IP address in a format other than the dotted decimal notation, the user may not be redirected. This is related with the operating system used on the PC. In this case, the PC considers the IP address string a name and tries to resolve the name. If the resolution fails, the PC will access a specific website. Generally, this address is not in dotted decimal notation. As a result, the PC cannot receive any ARP response and therefore cannot be redirected. To solve this problem, the user needs to enter an IP address that is not in the free IP range in dotted decimal notation.

If a user enters an address in the free IP range, the user cannot be redirected. This is because the device considers that the user wants to access a host in the free IP range. This is true even if no host with the IP address exists. To solve this problem, the user needs to enter an address not in the free IP range.

Check that you have configured an IP address in the free IP range for the Web server and a correct URL for redirection, and that the server provides Web services properly.
