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 describes managed objects for the Multiprotocol
Label Switching, Label Distribution Protocol (LDP) [18].
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 [22].
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
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
Expires September 2000 [Page 3]
INTERNET-DRAFT MPLS LDP MIB March 2000
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. Structure of the MIB
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for the Multiprotocol
Label Switching, Label Distribution Protocol (LDP) as defined in
[18].
3.1. Overview
The MIB provides objects to configure/set-up potential LDP sessions
on a specific LSR. A table is used to configure potential LDP
Sessions, where each row in the table initiates an LDP Session. This
is the mplsLdpEntityTable.
Another table, the mplsLdpEntityPeerTable, is a read-only table which
records information learned via discovery or from the session
initialization message. Each row in the EntityPeer Table represents
a peer which is known to a specific Entity. This table carries
information which is specific to the Entity-Peer interactions but is
not appropriate for the mplsLdpSessionTable.
A third table is used to show the actual sessions which have been, or
are in the process of being established. Each row represents a
specific session between an Entity (on this LSR) and a peer.
3.2. Interface Indexing
Interface Indexes as specified in [29] are used in the MIB. The
descriptions of the ifIndexes denote which ifIndex is being used.
NOTE: the use of ifIndex is for actual existing connections.
3.3. Future Considerations
The following aspects are not addressed in this document: VPN issues
(i.e. potential MIB objects such as the VPN Identifier are not
included at this time), and lastly, multicast issues are not
discussed.
Some of these issues need further clarification before adding to the
MIB.
3.4. Discussion of MIB Groups
Currently, there are four groups: the MPLS LDP General Group, the
MPLS LDP ATM Group, the MPLS LDP Frame Relay Group and the MPLS LDP
Notifications Group. The MPLS LDP General Group and the MPLS LDP
Notifications Group should always be supported. The MPLS LDP ATM
Expires September 2000 [Page 5]
INTERNET-DRAFT MPLS LDP MIB March 2000
Group is specific to ATM and should be supported only if LDP is using
ATM. Likewise, the MPLS LDP Frame Relay group is specific to Frame
Relay and should be supported only if LDP is using Frame Relay.
3.5. The MPLS LDP General Group
This group contains information about the specific LDP Entities which
are associated with this agent. Each LSR must have one LDP Entity.
3.5.1. The Label Distribution Protocol's Entity Table
The LDP Entity Table provides a way to configure the LSR for using
LDP. There must be at least one LDP Entity for the LSR to support
LDP.
Each entry/row in this table represents a single LDP Entity.
3.5.2. Row Creation in the MplsLdpEntity and Associated Tables
It should be noted that special care should be taken if MIB objects
which are used in the MPLS LDP Session Initialization need to be
changed AFTER Session Initialization has occurred. For example,
currently there is no way to modify a Label Range once a session has
been established. Thus, in order to do this, the entire session with
the peer needs to be torn down. All information (LIB and FEC)
learned during this session needs to be removed from the MIB. Then
and only then is it save to modify a Label Range. After
modification, the LDP Entity will need to go through the Session
Initialization again, in order to communicate the new Label Ranges to
the Peer and establish new sessions.
Please see AdminStatus and RowStatus objects in these tables for more
details.
3.5.3. The Label Distribution Protocol's Entity ATM Objects
There exists two tables to configure LDP for using ATM. These tables
are the mplsLdpEntityAtmParmsTable and the
mplsLdpEntityConfAtmLabelRangeTable.
The mplsLdpEntityAtmParmsTable provides a way to configure
information which would be contained in the 'Optional Parameter'
portion of an LDP PDU Initialization Message.
The mplsLdpEntityConfAtmLabelRangeTable provides a way to configure
information which would be contained in the 'ATM Label Range
Expires September 2000 [Page 6]
INTERNET-DRAFT MPLS LDP MIB March 2000
Components' portion of an LDP PDU Intialization Message.
3.5.4. The Label Distribution Protocol's Entity Frame Relay Objects
There exists two tables to configure LDP for using Frame Relay.
These tables are the mplsLdpEntityFrameRelayParmsTable and the
mplsLdpEntityConfFrLabelRangeTable.
The mplsLdpEntityFrameRelayParmsTable provides a way to configure
information which would be contained in the 'Optional Parameter'
portion of an LDP PDU Initialization Message.
The mplsLdpEntityConfFrLabelRangeTable provides a way to configure
information which would be contained in the portion of an LDP PDU
Intialization Message.
3.5.5. The Label Distribution Protocol's Entity Statistics Table
The LDP Entity Statistics Table will maintain counters related to an
LDP Entity. This Table should be a read-only table which contains
statistical information.
Each row in this table will be related to a single LDP Entity.
3.5.6. The LDP Entity Peer Table
The LDP Entity Peer Table is a read-only table which contains
information about LDP Peers known to LDP Entities. A row in this
table is related to one or more rows in the Hello Adjacency Table and
one or more rows in the Session Table. The information in the
Entity-Peer table is relevant to a Peer but is not the same
information that is used by the actual session(s) which are related
to this Peer. For example, the PathLimit information is gleaned from
the session initialization phase but is not part of a session if
there is a mismatch. In the event of a mismatch, then the session
will use the PathLimit set by the Entity (and not the Peer).
A separate table allows for a more comprehensive and coherent MIB
model.
3.5.7. The LDP Hello Adjacencies Table
This is a table of all adjacencies between all LPD Entities and all
LDP Peers. A Session may have one or more adjacencies.
Expires September 2000 [Page 7]
INTERNET-DRAFT MPLS LDP MIB March 2000
3.5.8. The LDP Session Table
The LDP Session Table is a read-only table. Each entry in this table
represents a single session between an LDP Entity and a Peer.
3.5.9. The LDP ATM Session Table
The MPLS LDP ATM Session Table is a read-only table which contains
session information specific to ATM.
3.5.10. The LDP Frame Relay Session Table
The MPLS LDP Frame Relay Session Table is a read-only table which
contains session information specific to Frame Relay.
3.5.11. The LDP Session Statistics Table
The MPLS LDP Session Stats Table is a read-only table which contains
statistical information on sessions.
3.5.12. The LDP Session Peer Address Table
The MPLS LDP Session Peer Address Table is a table which 'extends'
the mplsLdpSessionTable. This table is a read-only table which
stores Addresses learned after session initialization via "Address
Message" advertisement.
3.5.13. The LDP Label Information Base (LIB) Table
The MPLS LDP LIB Table is a read-only table which contains
information stored in the LIB. This table is indexed by a unique
number which could be used to represent the LSP segment related to
this LIB entry. The Lsp number corresponds to a FEC entry in the FEC
Table which is described next.
3.5.14. The LDP FEC Table
The FEC Table is a read-only table which contains FEC (Forwarding
Equivalence Class) information. Each entry/row represents a single
FEC Element.
Expires September 2000 [Page 8]
INTERNET-DRAFT MPLS LDP MIB March 2000
3.6. The LDP Notifications Group
3.6.1. LDP Notifications
Currently, there are two notifications:
mplsLdpFailedInitSessionThresholdExceeded and
mplsLdpPathVectorLimitMismatch.
mplsLdpFailedInitSessionThresholdExceeded is sent when the
'mplsLdpEntityFailedInitSessionThreshold' is exceeded. This
notification should indicate to the operator that there may be a
misconfigured mplsLdpEntityEntry because the session associated with
this Entity is not being established, and the Entity keeps trying to
establish the session. A side effect of this situation is that a row
in the mplsLdpSessionTable may not be reaching the operational state
as indicated by the
The mplsLdpPathVectorLimitMismatch notification is sent when the
Entity's Path Vector Limit and the Peer's Path Vector Limit do not
agree. In this situation a session could still be established
between the entity and the peer, using the Entity's Path Vector
Limit. For further details, please see Section 3.5.3 of the LDP
Specification [18].

DESCRIPTION
"An entry in this table provides a way to configure
a 'Generic Label' for LDP.
An entry in the 'mplsLdpEntityTable' will only have
associated entries in this Table if Generic Labels
are configured for a specific 'mplsLdpEntityEntry'.
Thus, not every 'mplsLdpEntityEntry' will have
associated entries in this table.
Expires September 2000 [Page 22]
INTERNET-DRAFT MPLS LDP MIB March 2000
The InterfaceIndex value for a Generic Label is
from the 'ifLayer' where the label is created. Likewise,
the ifType of the interface is the 'ifLayer' where the
label is created. For example, if an implementation
creates the generic label at the ifLayer which
has the 'ifType' of 'mpls', then the
'mplsLdpConfGenericIfIndexOrZero' object
should be set to the value of the InterfaceIndex
for this 'ifLayer'.
If the value of 'mplsLdpConfGenericIfIndexOrZero' is zero
then the InterfaceIndex value of this object is not known.
If this Generic Label is used, i.e. a session has been
established successfully and data is forwarded using this
label, then the value of the
'mplsLdpConfGenericIfIndexOrZero' object MUST be
updated by the network management entity
(e.g. SNMP agent) to reflect the InterfaceIndex
value for the 'ifLayer' that created the Generic Label.
To summarize, not all implementations may assign ifIndices
at a label's creation time, thus, an ifIndex value
may not be known, until a subsequent time. However,
once that ifIndex value is known, the
'mplsLdpConfGenericIfIndexOrZero' object
should be changed to reflect the ifIndex value."

5. Revision History
This section should be removed when this document is published as an
RFC.
5.1. Changes from <draft-ietf-mpls-ldp-mib-04.txt>
Editorial changes, fixing typo's, fixing wrapping lines, etc.
Updated references for latest drafts, and added [33] and [34] to
Reference Section.
Added to the Acknowledgements Section.
Changed the SYNTAX and DESCRIPTION of the
'mplsLdpLsrLoopDetectionCapable' object, so that it will also support
the loop detection by hop count.
Combined the 'mplsLdpEntityLoopDetectionForPV' and
'mplsLdpEntityPathVectorLimit' objects. The functionality of the
'mplsLdpEntityLoopDectionForPV' is now denoted by the value of 0
(zero) in the 'mplsLdpEntityPathVectorLimit' object. This results in
one less object 'mplsLdpEntityLoopDectionForPV' but does not
sacrifice functionality.
Changed 'mplsLdpLibLabelType' into two objects:
'mplsLdpLibInLabelType' and differ from the egress label type. The
MIB now reflects this.
The following items were changed as a result of the Frame Relay Forum
dropping support for 17-bit DLCIs: the MplsLabel TC description has
been modified, and other Frame Relay Object descriptions were also
modified (as specified in this section).
The MplsLabel TC was also modified and reference 3. was added to the
REFERENCE Clause.
MplsLdpLabelTypes TC was modified to use an enum.
InterfaceIndex support was added to the Entity information. This was
specifically requested by several members of the working group. An
additional table, mplsLdpEntityConfGenericTable as a way to configure
Generic Labels, and an object, 'mplsLdpConfGenericIfIndexOrZero was
added to map the InterfaceIndex used by Generic Labels. Objects were
also added to the 'mplsLdpEntityAtmParmsTable' and the and
'mplsLdpEntityFrIfIndex', respectively.
Changed the name of the 'mplsLdpEntityMtu' object to be
'mplsLdpEntityMaxPduLength' which is more consistent with the LDP
Expires September 2000 [Page 63]
INTERNET-DRAFT MPLS LDP MIB March 2000
Specification. Also, the description and SYNTAX were changed.
Changed the SYNTAX of the 'mplsLdpSessionMaxPduLength' to unsigned32
and changed the Range from (0..65535) to (1..65535).
Added and improved the front section discussion on SNMP
Notifications.
Also, modified the DESCRIPTION clause of the
Added objects to enable/disable the sending of traps:
Added an object to enable/disable sending traps for Sessions changing
from Up to Down, or Down to Up.
Added notifications to generate traps from session changing from Up
to Down, or Down to up.
Added a StorageType object to the Entity and associated tables which
are configurable.
Added a Discontinuity Time object to the Entity Table,
Added discussion on row creation in the Entity and other associated
Entity tables. This is a new Section in the Front part of the
document called:
Removed the 'mplsLdpEntityControlMethod'.
Made 'mplsLdpFecLspId' as part of the INDEX for the FEC table. This
is to allow FECs to map to multiple LSPs. Also add a RowPointer to a
row in the Session Table.
Added an operation status object, 'mplsLdpLspOperationStatus' and a
last Change object, 'mplsLdpLspLastChangeto the LIB Table. This will
be used to detect whether an LSP has changed its status.
Changed the name of the mplsLdpPeerTable to the
mplsLdpEntityPeerTable. This table contains information relevant to
Peers which are known to specific Entities. The indexing of this
table has also changed to include the Row in the Entity Table that
this Peer is known by. The mplsLdpHelloAdjacencyTable and the
mplsLdpSessionTable have been moved under this table. Since Hello
Adjacencies are related to Entity-Peer information and Sessions are
related to Entity-Peer information this was seen as a comprehensive
and coherent modelling. Associated descriptions in the front section
and in the tables have been changed to reflect this change.
Moved the 'mplsLdpConfFrLen' object from the
'mplsLdpEntityConfFrLabelRangeTable' to the
Expires September 2000 [Page 64]
INTERNET-DRAFT MPLS LDP MIB March 2000
'mplsLdpEntityFrameRelayParmsTable' since the Frame Relay
interface/port can only use one header length at a time, i.e. a
specific FR interface supports one address length for all VCs on that
interface. Also, changed the object so that it only supports 10 and
23 bit DLCI lengths. (The 17 bit length was dropped by the Frame
Relay Forum and thus, is no longer required.) The name of this
object was changed from 'mplsLdpConfFrLen' to 'mplsLdpEntityFrLen' to
fit in with the 'mplsLdpEntityFrameRelayParmsTable'.
Removed the seventeenDlciBits(1) value from the mplsLdpFrSessionLen
object. (The 17 bit length was dropped by the Frame Relay Forum and
thus, is no longer required.)
Corrected the range of the 'mplsLdpEntityIndexNext' object to include
0 (zero).
5.2. Changes from <draft-ietf-mpls-ldp-mib-03.txt>
Reworded the description of the mplsLdpAtmSessionTable to clarify
that one or MORE label range intersection(s) is/are represented in
this table.
Reworded the description of the mplsLdpFrameRelaySessionTable to
clarify that one or MORE label range intersection(s) is/are
represented in this table.
Added a new index, mplsLdpSessionPeerIndex, to the
mplsLdpSessionPeerAddressTable. This new index uniquely identifies
the entry within a given session. (Since adding
mplsLdpSessionPeerNextHopAddressType,
mplsLdpSessionPeerNextHopAddress to the INDEX clause of the
mplsLdpSessionPeerAddressTable leaves a table with only indices and
no objects, the work around was to add a new index which uniquely
differentiates an entry within a given session.)
Quite a few changes to the mplsLdpPeerTable. First, removed the
mplsLdpPeerIndex from the mplsLdpPeerTable and other tables. This
index served no purpose, so was removed. Second, removed the
objects: mplsLdpPeerInternetworkAddrType, and
mplsLdpPeerInternetworkAddr. Third, reworded the description of this
table to include information which is known during Session
Intialization attempts, the specific information has to do with Loop
Dection based on Path Vectors. Since Section 3.5.3 of the LDP Spec
when describing the PVLim says: "Although knowledge of a peer's path
vector limit will not change an LSR's behavior, it does enable the
LSR to alert an operator to a possible misconfiguration." and the
object mplsLdpPeerPathVectorLimit is sent as a varbind in the
mplsLdpPathVectorLimitMismatch notification.
Expires September 2000 [Page 65]
INTERNET-DRAFT MPLS LDP MIB March 2000
Removed the mplsLdpPeerIndex from the mplsLdpHelloAdjacencyTable.
Removed the "IANA Address Family Numbers MIB" section.
Updated the boiler.me from the ops web page dated Weds., Dec 22,
1999.
Updated the Security Section from the ops web page.
Added the following objects to the mplsLdpEntityTable:
mplsLdpEntityControlMethod, mplsLdpEntityLoopDectionForPV, and
mplsLdpEntityPathVectorLimit.
Removed mplsLdpSessionLabelAdvertisement,
mplsLdpSessionLoopDetectionForPV, and mplsLdpSessionPathVectorLimit
from the mplsLdpSessionTable.
Changed the mplsLdpPathVectorLimitMismatch Notification to send
mplsLdpEntityPathVectorLimit (instead of
mplsLdpSessionPathVectorLimit).
Copied the MplsLabel TC from draft-ietf-mpls-lsr-mib-00.txt and
replaced the MplsLdpGenAddr for mplsLdpLibInLabel and
mpslLdpLibOutLabel with MplsLabel.
The mplsLdpSessionIndex was removed throughout the MIB. This was
replaced by the object mplsLdpSessionDiscontinuityTime. The
motivation was to reduce the number of indices.
The descriptions for the objects in the mplsLdpSessionStatsTable,
mplsLdpSessionStatsUnknownMessageTypeErrors and
mplsLdpSessionStatsUnknownTlvErrors, have been updated to include a
reference to the mplsLdpSessionDiscontinuityTime object.
5.3. Changes from <draft-ietf-mpls-ldp-mib-02.txt>
Added Scalar Objects: mplsLdpLsrLoopDetectionPresent, and
mplsLdpEntityIndexNext.
Added the following objects to the mplsLdpEntityTable:
mplsLdpEntityProtocolVersion, mplsLdpEntityAdminStatus,
mplsLdpEntityOperStatus, mplsLdpEntityTargetedPeer,
mplsLdpEntityTargetedPeerAddrType, mplsLdpEntityTargetedPeerAddr, and
mplsLdpEntityHelloHoldTimer.
Changed the description of the mplsLdpEntityAtmParmsTable and added
the following objects to this table:
mplsLdpEntityAtmLsrConnectivity, mplsLdpEntityDefaultControlVpi,
mplsLdpEntityDefaultControlVci, mplsLdpEntityUnlabTrafVpi, and
Expires September 2000 [Page 66]
INTERNET-DRAFT MPLS LDP MIB March 2000
mplsLdpEntityUnlabTrafVci. NOTE: the last four objects were in
Version 01 of the MIB but were mistakenly omitted from Version 02.
Now, they are back.
Changed the indexing of the mplsLdpEntityConfAtmLabelRangeTable to
include the minimum VPI/VCI. This is to ensure that indices in this
table are unique.
Changed the indexing of the mplsLdpEntityConfFrLabelRangeTable, to
include the minimum DLCI value. This is to ensure that indices in
this table are unique.
Added [32] to Reference Section.
5.4. Changes from <draft-ietf-mpls-ldp-mib-01.txt>
The MIB was updated to correspond to draft-ietf-mpls-ldp-06.txt of
the LDP Specification [18].
The front section was updated.
The MIB was made to be less ATM-centric. Essentially, the ATM
specific objects where removed from the tables and placed in ATM
specific Tables. A "type" was added to the "base" tables and a row
is to be created in the ATM/FR/etc. "type" table. Apropos
compliance statements were added to reflect the separation of ATM and
Frame Relay objects into their respective tables.
Objects for Loop Detection were removed from describing the LDP
implementation (i.e. the scalars were removed) and Loop Dection
objects were added to the Session Table. (Although as the LDP
Specification indicates loop detection should be for an LSR within a
domain.)
The following tables were added: mplsLdpEntityAtmParmsTable,
mplsLdpEntityConfAtmLabelRangeTable, mplsLdpFrameRelayParmsTable,
mplsLdpConfFrLabelRangeTable, mplsLdpAtmSessionTable,
mpslLdpFrameRelaySessionTable, mplsLdpSessionPeerAddressTable,
mplsLdpLibTable, and the mplsLdpFecTable.
The following notifications were added: notification for Session
removal.
The following objects were removed from the Session Table:
mplsLdpSessionRole was removed (this can be determined by comparing
LSR Ids and does not need to be explicitely in the MIB.) ATM
specific objects (mplsLdpSessionAtmLabelRangeLowerBoundVpi
mplsLdpSessionAtmLabelRangeLowerBoundVci,
mplsLdpSessionAtmLabelRangeUpperBoundVpi
Expires September 2000 [Page 67]
INTERNET-DRAFT MPLS LDP MIB March 2000
mplsLdpSessionAtmLabelRangeUpperBoundVci) were removed and put into a
separate table. Frame Relay objects were added in a separate table.
Hello Adjacency Table was updated.
The objects, mplsLdpSessionRejectedParamErrors,
mplsLdpSessionRejectedNoHelloErrors, mplsLdpBadLdpIdentifierErrors,
mplsLdpBadPduLengthErrors, mplsLdpBadMessageLengthErrors,
mplsLdpBadTlvLengthErrors, mplsLdpMalformedTlvValueErrors,
mplsLdpKeepAliveTimerExpiredErrors, mplsLdpShutdownNotifReceived, and
mplsLdpShutdownNotifSent were added to the mplsLdpEntityStatsTable.
The mplsLdpSessionStatsTable was added to count statics based on a
per Session basis.
The mplLdpPeerConfAtmLabelRangeTable has been removed. There is no
need to configure information for a Peer. All information for a peer
is learned, thus peer information is read-only.
(Editorial) References were updated to reflect the documents which
this version was based on.
5.5. Changes from <draft-ietf-mpls-ldp-mib-00.txt>
Textual conventions were added for the LSR Identifier and the LDP
Identifier.
Top-level mib structure was added. The LDP MIB falls under a proposed
hierarchy of mpls.mplsProtocols.
The mib hierarchy within the LDP MIB was also changed. A new branch,
under mpls.mplsProtocols.mplsLdpMIB.mplsLdpObjects was added. This
branch is mplsLdpLsrObjects. Currently, this contains several new
scalar objects: mplsLdpLsrID, mplsLdpLsrLoopDetectionPresent,

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 contained in the mplsLdpEntityTable.
The objects contained in this table are responsible for setting up or
tearing down LSPs.
Expires September 2000 [Page 72]
INTERNET-DRAFT MPLS LDP MIB March 2000
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 RFC 2574 [RFC2574] and the View-
based Access Control Model RFC 2575 [RFC2575] 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.
