Configuration prerequisites and guidelines
• Configure IP addresses for the switch and servers as shown in Figure 61 and make sure the
host, switch, and servers can reach each other.
• Configure the RADIUS server correctly 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:
{ Configure direct portal authentication on VLAN-interface 100, the interface to which the host
is connected.
{ Configure portal authentication server detection, so that the switch can detect the
reachability of the portal authentication server by cooperating with the portal server
heartbeat function.
{ Configure portal user synchronization, so that the switch can synchronize portal user
information with the portal authentication server by cooperating with the portal user
heartbeat function.
