Juniper Questions (MX/ERX)

Hi there.. I'm trying to get an understanding on a FreeRadius installation how to enable the unisphere.dictionary. There are specific attributes in that file that we need such as "Unisphere-Ingress-Policy-Name". By default, this dictionary file is commented out due to "attribute conflicts". Can someone share a bit more info? I need unisphere attributes and also erx attributes to function on the same FreeRadius system ultimately .. We have a mixture of Juniper ERX equipment and Juniper MX equipment that needs to talk to FreeRadius. When I try to add a "Unisphere-Ingress-Policy-Name = 512k" for example in the users file I get "invalid integer" error. Thanks for any insight. Paul
