Information About RADIUS
The Remote Access Dial-In User Service (RADIUS) distributed client/server system allows you to secure
networks against unauthorized access. In the Cisco implementation, RADIUS clients run on Cisco Nexus
device and send authentication and accounting requests to a central RADIUS server that contains all user
authentication and network service access information.
RADIUS Network Environments
RADIUS can be implemented in a variety of network environments that require high levels of security while
maintaining network access for remote users.
You can use RADIUS in the following network environments that require access security:
• Networks with multiple-vendor network devices, each supporting RADIUS.
