1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines a set of MIB objects to manage a Power
Ethernet (DTE Power via MDI)Powered Device (PD) and/or power Source
Equipment (PSE).
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 [RFC2863].
2. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [RFC2571].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
1215 [RFC1215]. The second version, called SMIv2, is described
in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and
STD 58, RFC 2580 [RFC2580].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC 1157 [RFC1157]. A second version of
the SNMP message protocol, which is not an Internet standards
track protocol, is called SNMPv2c and described in RFC 1901
[RFC1901] and RFC 1906 [RFC1906]. The third version of the
message protocol is called SNMPv3 and described in RFC 1906
[RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [RFC1157]. A second set of
protocol operations and associated PDU formats is described in
D.Romascanu Expires August 2001 [Page 2]
INTERNET DRAFT Power Ethernet MIB February 2001
RFC 1905 [RFC1905].
o A set of fundamental applications described in RFC 2573
[RFC2573] and the view-based access control mechanism described
in RFC 2575 [RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
3. Overview
The emergence of IP telephony as an application that allows for voice
applications to be run over the same infrastructure as data
applications led to the emergence of Ethernet IP phones, with similar
functions and characteristics as the traditional phones. Powering a
phone is one of these functions that are being taken as granted. The
IEEE 802.3 Working Group initiated a standard work on this subject,
currently known as the IEEE 802.3af work [IEEE-802.3af].
The IEEE 802.3af WG will not define a full management interface, but
only the hardware registers that will allow for a management
interfaces to be built for a powered Ethernet device. The MIB module
defined in this document extends the Ethernet-like Interfaces MIB
[RFC2665] with the management objects required for the management of
the powered Ethernet devices and ports.
The following abrviations are defined in [IEEE-802.3af] and will be
used with the same significance in this document: PSE - Power
Sourcing Equipment; PD - Powered Device
4. MIB Structure
D.Romascanu Expires August 2001 [Page 3]
INTERNET DRAFT Power Ethernet MIB February 2001
This MIB module is composed of two tables and one MIB group.
The pethPsePortTable deines the objects used for the configuration
and describing the status of ports on a PSE device. Examples of PSE
devices are Ethernet switches that support power Ethernet and mid-
span boxes.
The pethPdPortTable defines the objects used for the configuration
and describing the status of ports on a PD device. Examples of PD
devices are Ethernet phones.
The pethMainPseObjects MIB group defines the management objects for a
managed main power source in a PSE device. Ethernet switches are one
example of boxes that would support these objects.
5. Evolution of the Document, Limitations and Future Work
The IEEE 802.3af is at this stage work in progress. The scope of this
document is to initiate standards work in the IETF in order to allow
for the publication of a standard track document conmtaining an SNMP
MIB simultaneously or close to the date of the publication of the
IEEE revised standard. It is expected that changes may be brought to
the IEEE proposal. There are aspects that were not yet included in
the first version of the MIB like use of notifications.

9. Security Considerations
There are a number of management objects defined in this MIB
that have a MAX-ACCESS clause of read-write and/or read-create.
Such objects may be considered sensitive or vulnerable in some
network environments. The support for SET operations in a
non-secure environment without proper protection can have a
negative effect on network operations.
There are a number of managed objects in this MIB that may
contain sensitive information. These are:
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.
SNMPv1 by itself is not a secure environment. Even if the
network itself is secure (for example by using IPSec), even then,
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 [RFC2274] and the
View-based Access Control Model [RFC2275] is RECOMMENDED.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those
principals (users) that have legitimate rights to indeed GET or
SET (change/create/delete) them.
