This document describes how Cisco Internetwork Operating System (IOS) choose Authentication, Authorization and Accounting (AAA) Server from the list of multiple AAA Servers configured, when a new style AAA Command Line Interpreter (CLI) "radius server <AAA Server name>" is used.
Cisco recommends that you meet this requirement before you attempt this configuration:
AAA Server is reachable from the IOS Device (referrred to as Client Router from here on)
Client Internet Protocol Address (IP Address) configured on AAA Server
User policies configured on AAA Server
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
"radius-server host <AAA Server IP address>" will be deprecated soon. Hence we need to migrate to new CLI "radius server <AAA Server name>". Refer the below example from a lab Router
Client(config)#radius-server host 192.168.10.1 Warning: This CLI will be deprecated soon. Please move to radius server <name> CLI.
