Configuring portal server detection and portal user
synchronization
Network requirements
As shown in Figure 52 , the host is directly connected to the switch (the access device). The host is
assigned with a public IP address either manually or through DHCP. A portal server serves as both a
portal authentication server and a portal Web server. A RADIUS server serves as the
authentication/accounting server.
Configure direct portal authentication on the switch, so the host can access only the portal server before
passing the authentication and access Internet resources after passing the authentication.
Configure the switch to do the following:
• Detect the reachability state of the portal authentication server.
• Send log messages upon state changes.
• Disable portal authentication when the authentication server is unreachable.
• Synchronize portal user information with the portal server periodically.

Configuration prerequisites and guidelines
• Configure IP addresses for the switch and servers as shown in Figure 52 and make sure the host,
switch, and servers can reach each other.
• Configure the RADIUS server properly to provide authentication and accounting functions.
• Configure the portal authentication server. Be sure to enable the server heartbeat function and the
user heartbeat function.
• Configure the switch (access device) as follows:
