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 needs to 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.
