Cisco IOS test aaa command

ags: #cisco #ios #aaa #radius

To test the reachability of a RADIUS server in a Cisco IOS, you can use the test command. This is useful if you want to setup 802.1X and verify the authentication server's response without using a supplicant.

Here is an example:

SW1# test aaa group radius server auth-port 1812 ubuntu ubuntu legacy

This checks if user "ubuntu" with password "ubuntu" can authenticate.
