Troubleshooting - H3C S5100-SI Operation Manual

Configuration procedure
Before enabling quick EAD deployment, be sure that:
The Web server is configured properly.
The default gateway of the user's PC is configured as the IP address of the connected
VLAN interface on the switch.
# Configure the URL for HTTP redirection.
<Sysname> 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 1/0/1

Troubleshooting

Symptom: A user cannot be redirected to the specified URL server, no matter what URL the
user enters in the IE address bar.
Solution:
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 switch considers that the user wants to access a host in the free IP range,
unconcerned about whether this PC exists or not. 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.
