Configuration prerequisites and guidelines

• Configure IP addresses for the router and servers as shown in Figure 99 and make sure the host,

router, and servers can reach each other.

• Configure the RADIUS server correctly to provide authentication/authorization functions.

• Configure the portal authentication server. Be sure to enable the server heartbeat function and the

user heartbeat function.

• Configure the router (access device) as follows:

{ Configure direct portal authentication on Ethernet 1/2, the interface to which the host is

connected.

{ Configure portal authentication server detection, so that the router can detect the reachability of

the portal authentication server by cooperating with the portal server heartbeat function.

{ Configure portal user synchronization, so that the router can synchronize portal user information

with the portal authentication server by cooperating with the portal user heartbeat function.

Configuring the portal authentication server

This example assumes that the portal server runs on IMC PLAT 5.1 SP1 (E0202P05) and IMC UAM 5.1

(E0301).

1. Configure the portal authentication server:

a. Log in to IMC and click the Service tab.

b. Select User Access Manager > Portal Service > Server from the navigation tree to enter the

portal server configuration page, as shown in Figure 100.

c. Configu

re the portal server heartbeat interval and user heartbeat interval.

d. Use the default settings for other parameters.

e. Click OK.
