I'm assuming Port 1813 is the "revised" RFC for RADIUS accounting? I'm glad to see these posted, as I haven't really come across them in any of my previous studying. Does anyone know, are they all TCP, both TCP/UDP, or UDP port services? Does it matter for the Sec+ exam?

Thanks for the post.

yes the 1813 is for the revised RFC accounting port.

Also the RADIUS are UDP protocols

The TACACS+ is a TCP protocol

you will probably want to study the port numbers and the difference between the RADIUS and TACACS+ for AAA (Authentication, authorization, and accounting) services
