MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"A conceptual row in this table is created automatically by an
LSR for each interface that is both capable of supporting
GMPLS and configured to support GMPLS. Note that
support of GMPLS is not limited to control plane signaling,
but may include data-plane-only function configured through
SNMP SET commands performed on this MIB module.
A conceptual row in this table may also be created via SNMP
SET commands or automatically by the LSR to supplement a
conceptual row in the mplsInterfaceTable where the interface
is not capable of GMPLS but where the other objects carried
in this row provide useful additional information for an
MPLS interface.
A conceptual row in this table will exist if and only if a
corresponding entry in the mplsInterfaceTable exists, and a
corresponding entry in the ifTable exists with ifType = mpls(166).
If the associated entry in the ifTable is operationally disabled
(thus removing the GMPLS capabilities on the interface) or the
entry in the mplsInterfaceTable is deleted, the corresponding entry
in this table MUST be deleted shortly thereafter.
The indexes are the same as for the mplsInterfaceTable. Thus, the
entry with index 0 represents the per-platform label space and
contains parameters that apply to all interfaces that
participate in the per-platform label space."REFERENCE"1. Multiprotocol Label Switching (MPLS) Label Switching

of the more complex label forms required for GMPLS that cannot
be held within the TEXTUAL-CONVENTION MplsLabel; that is, labels
that cannot be encoded within 32 bits. It is, nevertheless, also
capable of holding 32-bit labels or regular MPLS Labels if
desired.
Each entry in this table represents an individual GMPLS Label
value. The representation of Labels in tables in other MIB
modules may be achieved by a referrence to an entry in this
table by means of a row pointer into this table. The indexing
of this table provides for arbitrary indexing and also for
concatenation of labels.
For an example of label concatenation, see RFC 3945, section 7.1.
In essence, a GMPLS Label may be composite in order to identify
a set of resources in the data plane. Practical examples are
timeslots and wavelength sets (which are not contiguous like
wavebands).
The indexing mechanism allows multiple entries in this table to
be seen as a sequence of labels that should be concatenated.
Ordering is potentially very sensitive for concatenation."REFERENCE"1. Generalized Multiprotocol Label Switching (GMPLS)

MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"An entry in this table represents a single label value. There
are three indexes into the table.
- The interface index may be helpful to distinguish which
labels are in use on which interfaces or to handle cases
where there are a very large number of labels in use in the
system. When label representation is desired to apply to the
whole system or when it is not important to distinguish
labels by their interfaces, this index MAY be set to zero.
- The label index provides a way of identifying the label.
- The label sub-index is only used for concatenated labels. It
identifies each component label. When non-concatenated labels
are used, this index SHOULD be set to zero.
A storage type object is supplied to control the storage type
for each entry, but implementations should note that the storage
type of conceptual rows in other tables that include row
pointers to an entry in this table SHOULD dictate the storage
type of the rows in this table where the row in the other table

agent MUST ensure that this object's value remains consistent
with the storage type of any rows in other tables that contain
pointers to this row. In particular, the storage type of this
row must be at least as permanent as that of any row that points
to it.
Conceptual rows having the value 'permanent' need not
allow write-access to any columnar objects in the row."REFERENCE"1. Textual Conventions for SMIv2, STD 58, RFC 2579, section 2."DEFVAL{ volatile }

STATUScurrentDESCRIPTION"This variable is used to create, modify, and/or delete a row in
this table. When a row in this table has a row in the active(1)
state, no objects in this row can be modified except the
gmplsLabelRowStatus and gmplsLabelStorageType.
The gmplsLabelType object does not have a default and must be
set before a row can become active. The corresponding label
objects (dependent on the value of gmplsLabelType) should also
be set unless they happen to need to use the specified default
values as follows:
