Abstract Abstract
This document defines three new RADIUS attributes. For devices that This document defines three new RADIUS attributes. For devices that
implementing IP port ranges, these attributes are used to communicate implementing IP port ranges, these attributes are used to communicate
with a RADIUS server in order to configure and report TCP/UDP ports with a RADIUS server in order to configure and report TCP/UDP ports
and ICMP identifiers, as well as mapping behavior for specific hosts. and ICMP identifiers, as well as mapping behavior for specific hosts.
