Configuration prerequisites
The portal feature provides a solution for user identity authentication and security check. However, 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 properly. Local portal
authentication requires no independent portal server be installed.
• 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 the chapter "AAA configuration."
• 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 the chapter "AAA
configuration."
