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 192.168.1.200 auth-port 1812 ubuntu ubuntu legacy
This checks if user "ubuntu" with password "ubuntu" can authenticate.
