Quick question, did you tried with this module ( Juniper EX 2200 Series)
because the CoA is there:

I’ve been watching this as we are starting to use Juniper EX series
switches and I hope this will also solve the same issues I’ve
encountered with EX3300 switches on 5.3.1.

Using the value of the acctsessionid column in the radacct table worked.
Here's the attributes I used.

Thanks for the help Louis. Let me know if you need anymore information
to create the patch.

So the switch rejects (NAKs) our disconnect request.
We need to find which attribute to send it to ask it to disconnect
you.
This is where it gets “fun”.
Each vendor seems to have it’s own idea about that.
If I read this correctly, we need the session id:
http://www.juniper.net/documentation/en_US/junos13.3/topics/concept/aaa-radius-coa-overview.html
You would find that in the accounting tables of the database.
Look in the “radacct” table, under acctsessionid using the mac
address of the device (lowercase and without any delimiter).
Then what you can do as a proof of concept is to manually send a
disconnect request using radclient.
Save the attributes and values to send into a file, like this:
User-Name=$USER-NAME
Acct-Session-ID=$sessionid
and then pipe the file into radclient:
# cat file | radclient -c1 -r1 -x 172.22.0.201 disconnect
$RADIUS_SHARED_SECRET
If you can get it to disconnect, I can get you a patch that would
fix the EX4220, probably tomorrow.
