Configuration Example
Typical Configuration Examples of First-generation Web Authentication
Networking Requirements
The network is deployed with a Radius server, a Portal server (which may integrate the functions of
the Radius server), a DHCP server, a pass-through server (website), a DNS server, a core device, a
convergence device, and several access devices and user PCs.
The access devices support first-generation web authentication.
Networking Topology
Figure 2 Networking topology for web authentication solution
The user PCs are connected to the access devices, whose upstream ports are connected to the
convergence device. The convergence device is connected to the core device, which allows the
user PCs to access the Internet.
The servers are deployed in the server area and they are connected to the core device through an
internal network.
PC1 and PC2 obtain the IP addresses 192.168.4.11 and 192.168.4.12 from the DHCP server,
respectively. The IP address of the gateway serving PC1 and PC2 is 192.168.4.1.
The domain name of the Portal server is www.web_auth.com, which can be resolved by the internal
DNS server. The URL of the web authentication page is
