A user can perform portal authentication through a Web page. Before passing the authentication, the
user can access only the authentication page http://2.2.2.1:2331/portal and all Web requests will be
redirected to the authentication page. After passing the authentication, the user can access other
network resources.
# After the user passes authentication, use the following command to display information about the
portal user.
[Switch] display portal user interface vlan-interface 100
Total portal users: 1

Troubleshooting portal
No portal authentication page is pushed for users
Symptom
When a user is redirected to the IMC portal authentication server, no portal authentication page or
error message is prompted for the user. The login page is blank.
Analysis
The key configured on the portal access device and that configured on the portal authentication
server are inconsistent. As a result, packet verification fails, and the portal authentication server
refuses to push the authentication page.
Solution
Use the display portal server command on the access device to check whether a key is configured
for the portal authentication server.
• If no key is configured, configure the right key.
• If a key is configured, use the ip or ipv6 command in the portal authentication server view to
correct the key, or correct the key configured for the access device on the portal authentication
server.
