Configuration prerequisites
Although the portal feature provides a solution for user identity authentication and security check, the
portal feature cannot implement this solution by itself. RADIUS authentication must be configured on
the access device to cooperate with the portal feature to complete user authentication.
The prerequisites for portal authentication configuration are as follows:
• The portal server and the RADIUS server have been installed and configured correctly. Local
portal authentication requires no independent portal server be installed.
• With re-DHCP authentication, the IP address check function of the DHCP relay agent is
enabled on the access device, and the DHCP server is installed and configured correctly.
• The portal client, access device, and servers can reach each other.
• With RADIUS authentication, usernames and passwords of the users are configured on the
RADIUS server, and the RADIUS client configurations are performed on the access device. For
information about RADIUS client configuration, see "Configuring AAA."
• To implement extended portal functions, install and configure CAMS EAD or IMC EAD, and
make sure that the ACLs configured on the access device correspond to those specified for the
resources in the quarantined area and for the restricted resources on the security policy server.
For information about security policy server configuration on the access device, see
"Configuring AAA."
For installation and configuration about the security policy server, see CAMS EAD Security Policy
Component User Manual or IMC EAD Security Policy Help.
The ACL for resources in the quarantined area and that for restricted resources correspond to
isolation ACL and security ACL on the security policy server respectively.
You can modify the authorized ACLs on the access device. However, your changes take effect only
for portal users logging on after the modification.
For portal authentication to operate correctly, make sure the device name is no more than 16
characters.
