mplsOutSegmentTable

mplsOutSegmentTable

This table contains a representation of the outgoing segments from an LSR.

An entry in this table represents one outgoing segment. An entry can be created by a network administrator, an SNMP agent, or an MPLS signaling protocol. The object mplsOutSegmentOwner indicates the creator of this entry. The value of mplsOutSegmentRowStatus cannot be active (1) unless the ifTable entry corresponding to mplsOutSegmentInterface exists.

Note that the indexing of this table uses a single, arbitrary index (mplsOutSegmentIndex) to indicate which out-segment (for example: label) is being switched to from which in-segment (i.e: label) or in-segments. This is necessary because it is possible to have an equal-cost multi-path situation where two identical out-going labels are assigned to the same cross-connect (for example: they go to two different neighboring LSRs); thus, requiring two out-segments. In order to preserve the uniqueness of the references by the mplsXCEntry, an arbitrary integer must be used as the index for this table.

The index of this table is mplsOutSegmentIndex.

Implemented Specifications

1.3.6.1.2.1.10.166.2.1.7.1.1

mplsOutSegmentIndex

MplsIndexType

Not-accessible

This value contains a unique index for this row. While a value of a string containing the single octet 0x00 is not valid as an index for entries in this table, it can be supplied as a valid value to index the mplsXCTable to represent entries for which no out-segment has been configured or exists.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.10.166.2.1.7.1.2

mplsOutSegmentInterface

InterfaceIndexOrZero

Read-create

This value must contain the interface index of the outgoing interface. This object cannot be modified if mplsOutSegmentRowStatus is active(1). The mplsOutSegmentRowStatus cannot be set to active(1) until this object is set to a value corresponding to a valid ifEntry.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.2.1.7.1.3

mplsOutSegmentPushTopLabel

TruthValue

Read-create

This value indicates whether or not a top label should be pushed onto the outgoing packet's label stack. The value of this variable MUST be set to true(1) if the outgoing interface does not support pop-and-go (and no label stack remains).

For example, on ATM interface, or if the segment represents a tunnel origination. Note that it is considered an error in the case that mplsOutSegmentPushTopLabel is set to false, but the cross-connect entry which refers to this out-segment has a non-zero mplsLabelStackIndex. The LSR MUST ensure that this situation does not happen. This object cannot be modified if mplsOutSegmentRowStatus is active(1).

Get return false(2).

Currently, the maximum access is read-only; the return value false(2) is supported only.

1.3.6.1.2.1.10.166.2.1.7.1.4

mplsOutSegmentTopLabel

MplsLabel

Read-create

If mplsOutSegmentPushTopLabel is true then this represents the label that should be pushed onto the top of the outgoing packet's label stack. Otherwise this value SHOULD be set to 0 by the management station and MUST be ignored by the agent. This object cannot be modified if mplsOutSegmentRowStatus is active(1).

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.2.1.7.1.5

mplsOutSegmentTopLabelPtr

RowPointer

Read-create

If the label for this segment cannot be represented fully within the mplsOutSegmentLabel object, this object MUST point to the first accessible column of a conceptual row in an external table containing the label. In this case, the mplsOutSegmentTopLabel object SHOULD be set to 0 and ignored. This object MUST be set to zeroDotZero otherwise.

The default value is 0.0.

Currently, the maximum access is read-only; the return value 0 is supported only.

1.3.6.1.2.1.10.166.2.1.7.1.6

mplsOutSegmentNextHopAddrType

InetAddressType

Read-create

Indicates the next hop Internet address type. Only values unknown(0), ipv4(1) or ipv6(2) have to be supported.

A value of unknown(0) is allowed only when the outgoing interface is of type point-to-point. If any other unsupported values are attempted in a set operation, the agent MUST return an inconsistentValue error.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.2.1.7.1.7

mplsOutSegmentNextHopAddr

InetAddress

Read-create

The internet address of the next hop. The type of this address is determined by the value of the mplslOutSegmentNextHopAddrType object.

This object cannot be modified if mplsOutSegmentRowStatus is active(1).

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.2.1.7.1.8

mplsOutSegmentXCIndex

MplsIndexType

Read-only

Index into mplsXCTable which identifies which cross-connect entry this segment is part of. A value of the string containing the single octet 0x00 indicates that this entry is not referred to by any cross-connect entry.

When a cross-connect entry is created which this out-segment is a part of, this object MUST be updated by the agent to reflect the value of mplsXCIndex of that cross-connect entry.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.10.166.2.1.7.1.9

mplsOutSegmentOwner

MplsOwner

Read-only

Denotes the entity which created and is responsible for managing this segment.

Support 7 categories.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.10.166.2.1.7.1.10

mplsOutSegmentTrafficParamPtr

RowPointer

Read-create

This variable represents a pointer to the traffic parameter specification for this out-segment. This value may point at an entry in the MplsTunnelResourceEntry in the MPLS-TE-STD-MIB (RFC3812) RFC Editor: Please fill in RFC number. to indicate which traffic parameter settings for this segment if it represents an LSP used for a TE tunnel.

This value may optionally point at an externally defined traffic parameter specification table. A value of zeroDotZero indicates best-effort treatment.

By having the same value of this object, two or more segments can indicate resource sharing of such things as LSP queue space, and so on.

This object cannot be modified if mplsOutSegmentRowStatus is active(1).

For entries in this table that are preserved after a re-boot, the agent MUST ensure that their integrity be preserved, or this object should be set to 0.0 if it cannot.

The default value is 0.0.

Currently, the maximum access is read-only; the return value 0 is supported only.

1.3.6.1.2.1.10.166.2.1.7.1.11

mplsOutSegmentRowStatus

RowStatus

Read-create

For creating, modifying, and deleting this row. When a row in this table has a row in the active(1) state, no objects in this row can be modified except the mplsOutSegmentRowStatus or mplsOutSegmentStorageType.

Do not support Create, modify and Destroy.

Currently, the maximum access is read-only.

1.3.6.1.2.1.10.166.2.1.7.1.12

mplsOutSegmentStorageType

StorageType

Read-create

This variable indicates the storage type for this object. The agent MUST ensure that this object's value remains consistent with the associated mplsXCEntry. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row.Get return value nonvolatile(3).

Currently, the maximum access is read-only; the return value nonvolatile(3) is supported only.

Creation Restriction

The entries in this table cannot be created.

Modification Restriction

The entries in this table cannot be modified.

Deletion Restriction

The entries in this table cannot be deleted.

Access Restriction

This table is accessible after an LSP is established.
