HOW TO WIRED 802.1x FreeRadius RHEL6 configuration for Dummies?

[lux xul]

All-

brand New to linux and freeradius, networking. Im winging it as best I can.

Linux: RHEL6

Linux System Admin Dropdown with INSTALLED filter shows: freeRadius
2.2.6-6.el6_7(x86_64)
Command line "radiusd -v" shows "freeRadius version 3.0.8"

Confused. I downloaded the RHEL6 compatible 2.2.6 RPM and installed it
using yum. That was what I THOUGHT I was working with. I also ran Yum and
updated the servers database, etc.

Question 1: Are freeradius RPM files labeled differently than freeRadius
installation versions? Meaning a 2.2.6.el6_7 RPM can actually be the binary
of a freeRadius version 3.0.8?

Then...

Following the Using radtest and the HOW-TOs on the freeRadius site I have
configured and was able to verify that the freeRadius Server authenticates
PAP and EAP-MD5. I have spent several days trying to locate how to
configure the freeRadius server and 802.1x Port Security in a LINUX ONLY
(no ms windows) and WIRED only test lab on one RHEL6 linux box. I want to
eventually enlarge upon that n/w setup to include at least one separate
client node. One step at a time.

I find many tutorials on how to configure "freeRadius/802.1x client/server"
on WIFI and in MSwindows environment, or a combination of linux and MS
Windows.

Now, it may be my lack of experience and lack of linux/networking
understanding, but I cannot confidently follow tutorials that are not in
sync with my linux/wired only limitations, especially when written with
certain assumptions of a knowledge / experience base/vocabulary that I do
not possess at this time.

Question 2: Is there any available how to guide that may prove more basic
and "for dummies" that I may use to step through a freeRadius/802.1x/Wired
only/RHEL linux Only process?

thank you for your suggestions in advance.
I spent many hours trying to answer this so I wouldnt have to ask.
