Radius servers showing in config question

[ajwhite0]

Hello,

I'm just doing an audit of some old switches we still have running and looking at their configs, I see some have radius configs like this, all 3 seem to be working when I tested, but is/was the 3rd method showing as "DC3" the new way to configure this?  Also is there a show command to list the status of radius on a switch?

Thanks

radius-server host 192.168.14.10 key 7 074E114Dee3B490954
radius-server host 192.168.14.11 key 7 08607C4Fsd2B551B51

radius server DC3
 address ipv4 10.11.15.10 auth-port 1645 acct-port 1646
 key 7 15533Bs110187B286B

 - @ajwhite0    Yes the radius server defined as DC3 is using the new syntax in the particular running configuration.
                        For testing use the command : show  aaa servers 
                        On DC3 (configuration) you can for instance add : 
                                  

radius server DC3
 address ipv4 10.11.15.10 auth-port 1645 acct-port 1646
 key 7 15533Bs110187B286B

  automate-tester username testuser password testpass 

 This allows the switch to periodically send test authentication requests to verify server responsiveness without manual
 intervention ,

Hi 

1-For command to show server

Show aaa servers 

2- what difference between two way to config 

First method you can only specify IP/name of server and key and port 

Where second method you can additional add specific interface use to connect to server and vrf.
