Hello, I am trying to use my RADIUS server to designate user group memberships specifying QoS policies and monthly data caps. When authenticating, the server returns an AVP that tells what group a user is in, and the NAS will apply the associated QoS policies to his traffic. The RADIUS server checks if a user is over his data cap on every Access-Request and Interim-Update packet. When the user exceeds the data cap defined for his group, the RADIUS server originates a CoA and sends a new group assignment in which his traffic is throttled. Everything works fine now, but if the RADIUS server finds that a user is over his cap, it first returns its default group assignment taken from the radgroupreply table, then sends a CoA. Output from RADIUS: Sending Accounting-Response of id 122 to 127.0.0.1 port 33544 Access-Group = "Group1" WARNING: Empty pre-proxy section. Using default return values. Sending CoA-Request of id 223 to 127.0.0.1 port 3799 User-Name = "1907444" Access-Group = "ThrottledGroup" Finished request 8. So the NAS receives the default group assignment, then the throttled group assignment immediately after. To avoid confusion and transmitting unnecessary data, in the case when a data cap is exceeded, how to I prevent the RADIUS server from returning the default values from the radgroupreply table, and only send the CoA? Thank you, Amanda
