Abstract
This memo obsoletes RFC 2619 by deprecating the MIB table containing
IPv4-only address formats and defining a new table to add support for
version neutral IP address formats. The remaining MIB objects from
RFC 2619 are carried forward into this document.

Internet-Draft RADIUS Auth Server MIB (IPv6) October 2005
1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
This document uses terminology from RFC 2865 [RFC2865].
2. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
The objects defined within this memo relate to the Remote
Authentication Dial-In User Service (RADIUS) Authentication Server as
defined in RFC 2865 [RFC2865].
3. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
4. Scope of Changes
This document obsoletes RFC 2619 [RFC2619], RADIUS Authentication
Server MIB, by deprecating the radiusAuthClientTable table and adding
a new table, radiusAuthClientExtTable, containing
radiusAuthClientInetAddressType and radiusAuthClientInetAddress. The
purpose of these added MIB objects is to support version neutral IP
addressing formats. The existing table containing
radiusAuthClientAddress is deprecated. The remaining MIB objects
from RFC 2619 are carried forward into this document.
RFC 4001 [RFC4001], which defines the SMI Textual Conventions for
version neutral IP addresses, contains the following recommendation.
Nelson Expires April 21, 2006 [Page 3]
Internet-Draft RADIUS Auth Server MIB (IPv6) October 2005
'In particular, when revising a MIB module that contains IPv4
specific tables, it is suggested to define new tables using the
textual conventions defined in this memo [RFC 4001] that support all
versions of IP. The status of the new tables SHOULD be "current",
whereas the status of the old IP version specific tables SHOULD be
changed to "deprecated". The other approach, of having multiple
similar tables for different IP versions, is strongly discouraged.'
5. Structure of the MIB Module
The RADIUS authentication protocol, described in RFC 2865 [RFC2865],
distinguishes between the client function and the server function.
In RADIUS authentication, clients send Access-Requests, and servers
reply with Access-Accepts, Access-Rejects, and Access-Challenges.
Typically NAS devices implement the client function, and thus would
be expected to implement the RADIUS authentication client MIB, while
RADIUS authentication servers implement the server function, and thus
would be expected to implement the RADIUS authentication server MIB.
However, it is possible for a RADIUS authentication entity to perform
both client and server functions. For example, a RADIUS proxy may
act as a server to one or more RADIUS authentication clients, while
simultaneously acting as an authentication client to one or more
authentication servers. In such situations, it is expected that
RADIUS entities combining client and server functionality will
support both the client and server MIBs.
This MIB module contains fourteen scalars as well as a single table,
the RADIUS Authentication Client Table, which contains one row for
each RADIUS authentication client with which the server shares a
secret. Each entry in the RADIUS Authentication Client Table
includes thirteen columns presenting a view of the activity of the
RADIUS authentication server.
6. Deprecated Objects
The deprecated table in this MIB is carried forward from RFC 2619
[RFC2619]. There are two conditions under which it MAY be desirable
for managed entities to continue to support the deprecated table:
1. The managed entity only supports IPv4 address formats.
2. The managed entity supports both IPv4 and IPv6 address formats,
and the deprecated table is supported for backwards compatibility
with older management stations. This option SHOULD only be used
when the IP addresses in the new table are in IPv4 format and can
accurately be represented in both the new table and the
Nelson Expires April 21, 2006 [Page 4]
Internet-Draft RADIUS Auth Server MIB (IPv6) October 2005
deprecated table.
Managed entities SHOULD NOT instantiate the deprecated table
containing IPv4-only address objects when the RADIUS server address
represented in the table row is not an IPv4 address. Managed
entities SHOULD NOT return inaccurate values of IP address or SNMP
object access errors for IPv4-only address objects in otherwise
populated tables.

8. IANA Considerations
This document requires no new IANA assignments.
9. Security Considerations
There are no management objects defined in this MIB that have a MAX-
ACCESS clause of read-write and/or read-create. So, if this MIB is
implemented correctly, then there is no risk that an intruder can
alter or create any management objects of this MIB via direct SNMP
SET operations.
There are a number of managed objects in this MIB that may contain
sensitive information. These are:
radiusAuthClientIPAddress This can be used to determine the address
of the RADIUS authentication client with which the server is
communicating. This information could be useful in mounting an
attack on the authentication client.
radiusAuthClientInetAddress This can be used to determine the address
of the RADIUS authentication client with which the server is
communicating. This information could be useful in mounting an
attack on the authentication client.
It is thus important to control even GET access to these objects and
possibly to even encrypt the values of these object when sending them
over the network via SNMP. Not all versions of SNMP provide features
for such a secure environment.
SNMP versions prior to SNMPv3 do not provide a secure environment.
Even if the network itself is secure (for example by using IPSec),
there is no control as to who on the secure network is allowed to
access and GET/SET (read/change/create/delete) the objects in this
MIB.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model [RFC2574] and the View-based Access
Control Model [RFC2575] is recommended. Using these security
features, customer/users can give access to the objects only to those
principals (users) that have legitimate rights to GET or SET (change/
create/delete) them.
