Configuring RADIUS Server Monitoring Parameters

Cisco MDS 9000 Family switches can use the RADIUS protocol to communicate with remote AAA
servers. You can configure multiple RADIUS servers and server groups and set timeout and retry counts.
RADIUS is a distributed client/server protocol that secures networks against unauthorized access. In the
Cisco implementation, RADIUS clients run on Cisco MDS 9000 Family switches and send
authentication requests to a central RADIUS server that contains all user authentication and network
service access information.
This section defines the RADIUS operation, identifies its network environments, and describes its
configuration possibilities.
