Configuration prerequisites
The portal feature provides a solution for user identity authentication and security check. To
complete user identity authentication, portal must cooperate with RADIUS.
The prerequisites for portal authentication configuration are as follows:
• 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."
• T
o implement extended portal functions, install and configure 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 insta
llation and configuration about the security policy
server, see IMC EAD Security Policy Help.
Configuring a portal authentication server
Configure this feature when user authentication uses an external portal authentication server.
Perform this task to configure the following portal authentication server parameters:
• IP address of the portal authentication server.
• VPN instance of the portal authentication server.
• Shared encryption key used between the device and the portal authentication server.
• Destination UDP port number used by the device to send unsolicited portal packets to the portal
authentication server.
• Portal authentication server type, which must be the same as the server type the device actually
uses.
The device supports multiple portal authentication servers.
