Windows Server NPS and Cisco Catalyst Login

Hello, I am attempting to configure a Windows Server with the NPS role to permit admins to log into our Catalyst switches using standard AD credentials.  I've got things setup per a few different guides I've looked over, but on each login attempt the Windows Server log simply states the following...

"A RADIUS message with the Code field set to 1, which is not valid, was received on port 1813 from RADIUS client spare0042960-01. Valid values of the RADIUS Code field are documented in RFC 2865."

The commands I ran on the test switch are as follows.  Anyone seen this before?

 

 

aaa group server radius groupName
 server name serverName

aaa authentication login default group groupName local

ip radius source-interface Vlan1 

radius-server attribute 6 on-for-login-auth

radius server serverName
 address ipv4 <ip redacted> auth-port 1813 acct-port 1812
 retransmit 2
 key <redacted>

I figured this out.  I had the auth and acct ports mixed up.  Auth needs to be on 1812.  Oops!
