| mplsLdpAtmMIB | 1.3.6.1.2.1.116 | | | Copyright (C) The Internet Society (2003). This
version of this MIB module is part of RFCXXX; see
the RFC itself for full legal notices.
This MIB contains managed object definitions for
configuring and monitoring the Multiprotocol Label
Switching (MPLS), Label Distribution Protocol (LDP),
utilizing Asynchronous Transfer Mode (ATM) as the Layer 2
media. |
| mplsLdpAtmObjects | 1.3.6.1.2.1.116.1 | | | |
| mplsLdpEntityAtmObjects | 1.3.6.1.2.1.116.1.1 | | | |
| mplsLdpEntityAtmTable | 1.3.6.1.2.1.116.1.1.1 | | not-accessible | This table contains information about the
ATM specific information which could be used
in the 'Optional Parameters' and other ATM specific
information.
This table 'extends' the mplsLdpEntityTable when
ATM as the Layer 2 media. |
| mplsLdpEntityAtmEntry | 1.3.6.1.2.1.116.1.1.1.1 | | not-accessible | An entry in this table represents the ATM parameters
and ATM information for this LDP entity. |
| NUM mplsLdpEntityAtmIfIndexOrZero | 1.3.6.1.2.1.116.1.1.1.1.1 | InterfaceIndexOrZero | read-create | This value represents either the InterfaceIndex of
the 'ifLayer' where the ATM Labels 'owned' by this
entry were created, or 0 (zero). The value of zero
means that the InterfaceIndex is not known. For example,
if the InterfaceIndex is created subsequent to the
ATM Label's creation, then it would not be known.
However, if the InterfaceIndex is known, then it must
be represented by this value.
If an InterfaceIndex becomes known, then the
network management entity (e.g. SNMP agent) responsible
for this object MUST change the value from 0 (zero) to the
value of the InterfaceIndex. If an ATM Label is
being used in forwarding data, then the value of this
object MUST be the InterfaceIndex. |
| INT mplsLdpEntityAtmMergeCap | 1.3.6.1.2.1.116.1.1.1.1.2 | INTEGER | read-create | Denotes the Merge Capability of this Entity.
This is the EXACT value for the ATM Session Parameter,
field M (for ATM Merge Capabilities). The ATM Session Parameter
is an optional parameter in the Initialization Message.
The description from rfc3036.txt is:
'M, ATM Merge Capabilities
Specifies the merge capabilities of an ATM switch. The
following values are supported in this version of the
specification:
Value Meaning
0 Merge not supported
1 VP Merge supported
2 VC Merge supported
3 VP & VC Merge supported
If the merge capabilities of the LSRs differ, then:
- Non-merge and VC-merge LSRs may freely interoperate.
- The interoperability of VP-merge-capable switches with non-
VP-merge-capable switches is a subject for future study.
When the LSRs differ on the use of VP-merge, the session is
established, but VP merge is not used.'

description of this feature. |
| U32 mplsLdpEntityAtmLRComponents | 1.3.6.1.2.1.116.1.1.1.1.3 | Unsigned32 | read-create | Number of Label Range Components in the Initialization
message. This also represents the number of entries
in the mplsLdpEntityAtmLRTable which correspond
to this entry.
This is the EXACT value for the ATM Session Parameter,
field N (for Number of label range components). The ATM
Session Parameter is an optional parameter in the Initialization
Message.
The description from rfc3036.txt is:
'N, Number of label range components
Specifies the number of ATM Label Range Components
included in the TLV.'

description of this feature. |
| INT mplsLdpEntityAtmVcDirectionality | 1.3.6.1.2.1.116.1.1.1.1.4 | INTEGER | read-create | If the value of this object is 'bidirectional(0)',
a given VCI, within a given VPI, is used as a
label for both directions independently.
If the value of this object is 'unidirectional(1)',
a given VCI within a VPI designates one direction.
This is the EXACT value for the ATM Session Parameter,
field D (for VC Directionality). The ATM Session Parameter
is an optional parameter in the Initialization Message.
The description from rfc3036.txt is:
'D, VC Directionality
A value of 0 specifies bidirectional VC capability, meaning the
LSR can (within a given VPI) support the use of a given VCI as
a label for both link directions independently. A value of 1
specifies unidirectional VC capability, meaning (within a given
VPI) a given VCI may appear in a label mapping for one
direction on the link only. When either or both of the peers
specifies unidirectional VC capability, both LSRs use
unidirectional VC label assignment for the link as follows.
The LSRs compare their LDP Identifiers as unsigned integers.
The LSR with the larger LDP Identifier may assign only odd-
numbered VCIs in the VPI/VCI range as labels. The system with
the smaller LDP Identifier may assign only even-numbered VCIs
in the VPI/VCI range as labels.'
Please refer to the following reference for a complete
description of this feature. |
| INT mplsLdpEntityAtmLsrConnectivity | 1.3.6.1.2.1.116.1.1.1.1.5 | INTEGER | read-create | The peer LSR may be connected indirectly by means of an
ATM VP so that the VPI values may be different on either
endpoint so the label MUST be encoded entirely within the
VCI field. |
| OID mplsLdpEntityAtmDefaultControlVpi | 1.3.6.1.2.1.116.1.1.1.1.6 | AtmVpIdentifier | read-create | The default VPI value for the non-MPLS connection. The
default value of this is 0 (zero) but other values may
be configured. This object allows a different value
to be configured. |
| OID mplsLdpEntityAtmDefaultControlVci | 1.3.6.1.2.1.116.1.1.1.1.7 | MplsAtmVcIdentifier | read-create | The Default VCI value for a non-MPLS connection. The
default value of this is 32 but other values may be
configured. This object allows a different value to
be configured. |
| OID mplsLdpEntityAtmUnlabTrafVpi | 1.3.6.1.2.1.116.1.1.1.1.8 | AtmVpIdentifier | read-create | VPI value of the VCC supporting unlabeled traffic. This
non-MPLS connection is used to carry unlabeled (IP)
packets. The default value is the same as the default
value of the 'mplsLdpEntityAtmDefaultControlVpi', however
another value may be configured. |
| OID mplsLdpEntityAtmUnlabTrafVci | 1.3.6.1.2.1.116.1.1.1.1.9 | MplsAtmVcIdentifier | read-create | VCI value of the VCC supporting unlabeled traffic.
This non-MPLS connection is used to carry unlabeled (IP)
packets. The default value is the same as the default
value of the 'mplsLdpEntityAtmDefaultControlVci', however
another value may be configured. |
| STO mplsLdpEntityAtmStorageType | 1.3.6.1.2.1.116.1.1.1.1.10 | StorageType | read-create | The storage type for this conceptual row. Conceptual rows
having the value 'permanent(4)' MAY allow write-access to any
columnar objects in the row, except for setting the
mplsLdpEntityAtmRowStatus to 'destroy(6)'. |
| ROW mplsLdpEntityAtmRowStatus | 1.3.6.1.2.1.116.1.1.1.1.11 | RowStatus | read-create | The status of this conceptual row. All writable objects in this
row may be modified at any time, however, as described in
detail in the section entitled, 'Changing Values After Session
Establishment', and again described in the
DESCRIPTION clause of the mplsLdpEntityAdminStatus object,
if a session has been initiated with a Peer,
changing objects in this table will
wreak havoc with the session and interrupt traffic. To repeat again:
the recommended procedure is to set the mplsLdpEntityAdminStatus to
down, thereby explicitely causing a session to be torn down. Then,
change objects in this entry, then set the mplsLdpEntityAdminStatus
to enable which enables a NEW session to be initiated.
NOTE: This RowStatus object should
have the same value of the 'mplsLdpEntityRowStatus'
related to this entry. |
| mplsLdpEntityAtmLRTable | 1.3.6.1.2.1.116.1.1.2 | | not-accessible | The MPLS LDP Entity ATM Label Range (LR) Table.
The purpose of this table is to provide a mechanism
for configuring a contiguous range of vpi's
with a contiguous range of vci's, or a 'label range'
for LDP Entities.
LDP Entities which use ATM must have at least one
entry in this table. |
| mplsLdpEntityAtmLREntry | 1.3.6.1.2.1.116.1.1.2.1 | | not-accessible | A row in the LDP Entity ATM Label
Range Table. One entry in this table contains
information on a single range of labels
represented by the configured Upper and Lower
Bounds VPI/VCI pairs. These are the same
data used in the Initialization Message.
NOTE: The ranges for a specific LDP Entity
are UNIQUE and non-overlapping. For example,
for a specific LDP Entity index, there could
be one entry having LowerBound vpi/vci == 0/32, and
UpperBound vpi/vci == 0/100, and a second entry
for this same interface with LowerBound
vpi/vci == 0/101 and UpperBound vpi/vci == 0/200.
However, there could not be a third entry with
LowerBound vpi/vci == 0/200 and
UpperBound vpi/vci == 0/300 because this label
range overlaps with the second entry (i.e. both
entries now have 0/200).
A row will not be created unless a unique and
non-overlapping range is specified. Thus, row
creation implies a one-shot row creation of
LDP EntityID and LowerBound vpi/vci and
UpperBound vpi/vci. At least one label
range entry for a specific LDP Entity MUST
include the default VPI/VCI values denoted
in the LDP Entity Table. |
| OID mplsLdpEntityAtmLRMinVpi | 1.3.6.1.2.1.116.1.1.2.1.1 | AtmVpIdentifier | not-accessible | The minimum VPI number configured for this range.
The value of zero is a valid value for the VPI portion
of the label. |
| OID mplsLdpEntityAtmLRMinVci | 1.3.6.1.2.1.116.1.1.2.1.2 | MplsAtmVcIdentifier | not-accessible | The minimum VCI number configured for this range. |
| OID mplsLdpEntityAtmLRMaxVpi | 1.3.6.1.2.1.116.1.1.2.1.3 | AtmVpIdentifier | read-create | The maximum VPI number configured for this range. |
| OID mplsLdpEntityAtmLRMaxVci | 1.3.6.1.2.1.116.1.1.2.1.4 | MplsAtmVcIdentifier | read-create | The maximum VCI number configured for this range. |
| STO mplsLdpEntityAtmLRStorageType | 1.3.6.1.2.1.116.1.1.2.1.5 | StorageType | read-create | The storage type for this conceptual row. Conceptual rows
having the value 'permanent(4)' need not allow write-access to any
columnar objects in the row. |
| ROW mplsLdpEntityAtmLRRowStatus | 1.3.6.1.2.1.116.1.1.2.1.6 | RowStatus | read-create | The status of this conceptual row. All writable objects in this
row may be modified at any time, however, as described in
detail in the section entitled, 'Changing Values After Session
Establishment', and again described in the
DESCRIPTION clause of the mplsLdpEntityAdminStatus object,
if a session has been initiated with a Peer,
changing objects in this table will
wreak havoc with the session and interrupt traffic. To repeat again:
the recommended procedure is to set the mplsLdpEntityAdminStatus to
down, thereby explicitely causing a session to be torn down. Then,
change objects in this entry, then set the mplsLdpEntityAdminStatus
to enable which enables a NEW session to be initiated.
There must exist at least one entry in this
table for every LDP Entity that has
'mplsLdpEntityOptionalParameters' object with
a value of 'atmSessionParameters'.
NOTE: This RowStatus object should
have the same value of the 'mplsLdpEntityRowStatus'
related to this entry. |
| mplsLdpAtmSesObjects | 1.3.6.1.2.1.116.1.2 | | | |
| mplsLdpAtmSesTable | 1.3.6.1.2.1.116.1.2.1 | | not-accessible | A table which relates Sessions in the
'mplsLdpSessionTable' and their label
range intersections. There could be one
or more label range intersections between an
LDP Entity and LDP Peer using ATM as the underlying
media. Each row represents a single label range
intersection.
NOTE: this table cannot use the 'AUGMENTS'
clause because there is not necessarily a one-to-one
mapping between this table and the mplsLdpSessionTable. |
| mplsLdpAtmSesEntry | 1.3.6.1.2.1.116.1.2.1.1 | | not-accessible | An entry in this table represents information on a
single label range intersection between an LDP Entity
and LDP Peer.
The information contained in a row is read-only. |
| OID mplsLdpSesAtmLRLowerBoundVpi | 1.3.6.1.2.1.116.1.2.1.1.1 | AtmVpIdentifier | not-accessible | The minimum VPI number for this range. |
| OID mplsLdpSesAtmLRLowerBoundVci | 1.3.6.1.2.1.116.1.2.1.1.2 | MplsAtmVcIdentifier | not-accessible | The minimum VCI number for this range. |
| OID mplsLdpSesAtmLRUpperBoundVpi | 1.3.6.1.2.1.116.1.2.1.1.3 | AtmVpIdentifier | read-only | The maximum VPI number for this range. |
| OID mplsLdpSesAtmLRUpperBoundVci | 1.3.6.1.2.1.116.1.2.1.1.4 | MplsAtmVcIdentifier | read-only | The maximum VCI number for this range. |

| mplsLdpAtmGroups | 1.3.6.1.2.1.116.2.1 | | | |
| mplsLdpAtmGroup | 1.3.6.1.2.1.116.2.1.1 | | | Objects that apply to all MPLS LDP implementations
using ATM as the Layer 2. |

| mplsLdpAtmModuleFullCompliance | 1.3.6.1.2.1.116.2.2.1 | | | The Module is implemented with support for
read-create and read-write. In other words,
both monitoring and configuration
are available when using this MODULE-COMPLIANCE. |
| mplsLdpAtmModuleReadOnlyCompliance | 1.3.6.1.2.1.116.2.2.2 | | | The Module is implemented with support for
read-only. In other words, only monitoring
is available by implementing this MODULE-COMPLIANCE. |
