Abstract Abstract
This memo defines a set of extensions which instrument RADIUS
authentication server functions. These extensions represent a
portion of the Management Information Base (MIB) for use with network
management protocols in the Internet community. Using these
extensions IP-based management stations can manage RADIUS
authentication servers.
This memo obsoletes RFC 2619 by deprecating the MIB table containing This memo obsoletes RFC 2619 by deprecating the MIB table containing
IPv4-only address formats and defining a new table to add support for IPv4-only address formats and defining a new table to add support for
version neutral IP address formats. The remaining MIB objects from version neutral IP address formats. The remaining MIB objects from
RFC 2619 are carried forward into this document. RFC 2619 are carried forward into this document. This memo also adds
UNITS and Reference clauses to selected objects.

This document uses terminology from RFC 2865 [RFC2865]. This document uses terminology from RFC 2865 [RFC2865].
This document uses the word "malformed" with respect to RADIUS
packets, particularly in the context of counters of "malformed
packets". While RFC 2865 does not provide an explicit definition of
"malformed", malformed generally means that the implementation has
determined the packet does not match the format defined in RFC 2865.
Some implementations may determine that packets are malformed when
the Vendor Specific Attribute (VSA) format does not follow the RFC
2865 recommendations for VSAs. Those implementations are used in
deployments today, and thus set the de-facto definition of
"malformed".

2. The managed entity supports both IPv4 and IPv6 address formats, 2. The managed entity supports both IPv4 and IPv6 address formats,
and the deprecated table is supported for backwards compatibility and the deprecated table is supported for backwards compatibility
with older management stations. This option SHOULD only be used with older management stations. This option SHOULD only be used
when the IP addresses in the new table are in IPv4 format and can when the IP addresses in the new table are in IPv4 format and can
