2-4Configuration procedureBefore enabling quick EAD deployment, be sure that:z The Web server is configured properly.z The default gateway of the user’s PC is configured as the IP address of the connected VLANinterface on the switch.# Configure the URL for HTTP redirection. system-view[Sysname] dot1x url http://192.168.0.111# Configure a free IP range.[Sysname] dot1x free-ip 192.168.0.111 24# Set the ACL timer to 10 minutes.[Sysname] dot1x timer acl-timeout 10# Enable dot1x globally.[Sysname] dot1x# Enable dot1x for GigabitEthernet 1/0/1.[Sysname] dot1x interface GigabitEthernet 1/0/1TroubleshootingSymptom: A user cannot be redirected to the specified URL server, no matter what URL the user entersin the IE address bar.Solution:z If a user enters an IP address in a format other than the dotted decimal notation, the user may notbe redirected. This is related with the operating system used on the PC. In this case, the PCconsiders the IP address string a name and tries to resolve the name. If the resolution fails, the PCwill 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 thisproblem, the user needs to enter an IP address that is not in the free IP range in dotted decimalnotation.z If a user enters an address in the free IP range, the user cannot be redirected. This is because theswitch considers that the user wants to access a host in the free IP range, unconcerned aboutwhether this PC exists or not. To solve this problem, the user needs to enter an address not in thefree IP range.z Check that you have configured an IP address in the free IP range for the Web server and a correctURL for redirection, and that the server provides Web services properly.
