Prerequisites for portal authentication
The portal feature provides a solution for user identity authentication and security check. To complete user identity authentication, portal must cooperate with RADIUS.
Before you configure portal, you must complete the following tasks:
The portal authentication server, portal Web server, and RADIUS server have been installed and configured correctly.
To use the re-DHCP portal authentication mode, make sure 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.
To use the remote RADIUS server, configure usernames and passwords on the RADIUS server, and configure the RADIUS client 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. Make sure the ACLs configured on the access device correspond to the isolation ACL and the security ACL 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.
