Vantage RADIUS User’s Guide

Getting to Know Your Vantage RADIUS 1-7

Client usernames and passwords are forwarded from a wireless network to Vantage RADIUS, which then

validates them against its own list. This ensures that only individuals with valid accounts will be granted

network access.

The following gives an overview of Vantage RADIUS’ role in a network.

• Wireless station A attempts to communicate with B over the wireless network via C.

• C sends a “request identity” message to A for authentication.

• A replies with identity information, including username and password.

• C communicates with Vantage RADIUS, which checks the user information against its list of valid

accounts and determines whether or not to authenticate A.

• A is authenticated and can communicate with B over the wireless network.
