       RADIUS Extensions for IP Port Configuration and Reporting
                draft-ietf-radext-ip-port-radius-ext-17

Abstract

   This document defines three new RADIUS attributes.  For devices that
   implement IP port ranges, these attributes are used to communicate
   with a RADIUS server in order to configure and report IP transport
   ports, as well as mapping behavior for specific hosts.  This
   mechanism can be used in various deployment scenarios such as
   Carrier-Grade NAT, IPv4/IPv6 translators, Provider WLAN Gateway, etc.
   This document defines a mapping between some RADIUS attributes and
   IPFIX Information Element Identifiers.
