NE8000F1A - Does not respond Disconnect-Messages

Hi,

I'm trying to setup my NE8000F1A to serve as BRAS with Splynx. I can connect CPEs via PPPoE and assign rates without problem, but, when I send a disconnect-request, the router does not answer.

From the splynx server:

# echo "Framed-IP-Address = 170.233.117.254, NAS-IP-Address = 172.16.2.9" | /usr/bin/sudo /usr/bin/radclient 172.16.2.9:3799 disconnect hqk#g6RXondWSL*6

(0) No reply from server for ID 45 socket 3

On the NE8K I see the dyn-auth port open. Both appliances are in the same L2 network ( 172.16.2.0/24 )
