• Each Web Authentication VLAN must have a virtual interface (VE).
• The VE must have at least one assigned IPv4 address.
Web Authentication is enabled on a VLAN. That VLAN becomes a Web Authentication VLAN that
does the following:
• Forwards traffic from authenticated hosts, just like a regular VLAN.
• Blocks traffic from unauthenticated hosts except from ARP, DHCP, DNS, HTTP, and HTTPs that
are required to perform Web Authentication.
Figure 165 shows the basic components of a network topology where Web Authentication is used.
You will need:
• A Dell PowerConnect switch running a software release that supports Web Authentication
• DHCP server, if dynamic IP addressing is to be used
• Computer/host with a web browser
Your configuration may also require a RADIUS server with some Trusted Source such as LDAP or
Active Directory.
NOTE
The Web server, RADIUS server, and DHCP server can all be the same server.
