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 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 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.
Specifying the portal server for Layer 3 portal
authentication
Perform this task to specify portal server parameters for Layer 3 portal authentication, including the portal
server IP address, shared encryption key, server port, and the URL address for Web authentication.
According to the networking environment, you can configure a remote portal server or a local portal
server as needed.
• To configure a remote portal server, specify the IP address of the remote portal server.
