Description: Manages MPLS Label Switching Router (LSR) functions on H3C/3Com equipment, providing cross-connect table and label operation management.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is A3COM-HUAWEI-MPLS-LSR-MIB?

A3COM-HUAWEI-MPLS-LSR-MIB manages Multiprotocol Label Switching (MPLS) Label Switching Router functions on H3C/3Com routers and switches, covering per-interface label-space configuration and cross-connect/label operation as defined by the IETF MPLS architecture draft referenced in its module_desc. It exposes per-interface label range configuration (minimum/maximum inbound and outbound labels), bandwidth allocation and availability, and label-participation type, together with a performance table for interface-level MPLS statistics. This MIB supports monitoring of both configuration correctness and live performance of the MPLS control/forwarding plane: mplsInterfaceTotalBandwidth versus mplsInterfaceAvailableBandwidth reveals real-time bandwidth exhaustion on an LSR-facing interface, functioning as a performance/capacity health indicator for the routing software and underlying interface hardware. Dependency: it is explicitly derived from the IETF MPLS architecture Internet-Draft (draft-ietf-mpls-arch-06) and aligned with the standard MPLS-LSR object model. Deployment is on MPLS-enabled H3C/3Com core and edge routers in a service-provider or large enterprise MPLS backbone. Engineers can download the A3COM-HUAWEI-MPLS-LSR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-MPLS-LSR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

H3C/3Com MPLS-enabled routers and switches

Monitoring Examples

An admin would walk mplsInterfaceConfTable (indexed by mplsInterfaceConfIndex) to confirm the mplsInterfaceLabelMinIn/mplsInterfaceLabelMaxIn and mplsInterfaceLabelMinOut/mplsInterfaceLabelMaxOut label ranges are correctly provisioned on a given LSR-facing interface. Comparing mplsInterfaceAvailableBandwidth against mplsInterfaceTotalBandwidth in mplsInterfacePerfTable over time would reveal an MPLS interface approaching bandwidth exhaustion, prompting a capacity upgrade or traffic-engineering adjustment before label-switched paths start experiencing congestion.

What Can Be Monitored

How to Use in IPNetwork Monitor

Example using mplsInterfaceFailedLabelLookup OID:

Select an H3C/3Com MPLS router as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type mplsInterfaceFailedLabelLookup into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This object counts the number of labeled packets that have been received on this interface and were discarded because there was no matching cross-connect entry. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

If the value of the mplsInterfaceConfIndex for this entry is zero, then only the perPlatform(0) bit MUST be set and the perInterface(1) bit is meaningless. If the perInterface(1) bit is set then the value of mplsInterfaceLabelMinIn, mplsInterfaceLabelMaxIn, mplsInterfaceLabelMinOut, and mplsInterfaceLabelMaxOut for this entry reflect the label ranges for this interface. If only the perPlatform(0) bit is set, then the value of mplsInterfaceLabelMinIn, mplsInterfaceLabelMaxIn, mplsInterfaceLabelMinOut, and mplsInterfaceLabelMaxOut for this entry must be identical to the instance of these objects with index 0.
C32 mplsInterfaceOutFragments	1.3.6.1.4.1.43.45.1.5.12.1.1.2.1.4	Counter32	read-only	This object counts the number of outgoing MPLS packets that required fragmentation before transmission on this interface.

The value 0 indicates that no unassigned entries are available. To obtain an mplsLabelStackIndex value for a new entry, the manager issues a management protocol retrieval operation to obtain the current value of this object. After each retrieval operation, the agent should modify the value to reflect the next unassigned index. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.

If the number of unassigned entries is exhausted, this object will take on the value of 0. To obtain the mplsOutSegmentIndex value for a new entry, the manager must first issue a management protocol retrieval operation to obtain the current value of this object. The agent should modify the value to reflect the next unassigned index after each retrieval operation. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.

T/F mplsOutSegmentPushTopLabel	1.3.6.1.4.1.43.45.1.5.12.1.1.6.1.3	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 if the outgoing interface does not support pop- and-go (for example an ATM interface) or if it is 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

NUM mplsOutSegmentTrafficParamPtr	1.3.6.1.4.1.43.45.1.5.12.1.1.6.1.10	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 mplsTrafficParamTable to indicate which mplsTrafficParamEntry is to be assigned to this segment. This value may optionally point at an externally defined traffic parameter specification table. A value of zero-dot-zero indicates best- effort treatment. By having the same value of this object, two or more segments can indicate resource sharing.
I32 mplsOutSegmentXCIndex	1.3.6.1.4.1.43.45.1.5.12.1.1.6.1.8	Integer32	read-only	Index into mplsXCTable which identifies which cross- connect entry this segment is part of. A value of zero 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 is automatically updated to reflect the value of mplsXCIndex of that cross-connect entry.
mplsPerfGroup	1.3.6.1.4.1.43.45.1.5.12.1.3.1.6			Collection of objects providing performance information about an LSR.

mplsTrafficParamEntry	1.3.6.1.4.1.43.45.1.5.12.1.1.14.1		not-accessible	An entry in this table represents the TrafficParam objects for one or more in or out segments. A single entry can be pointed to by multiple segments indicating resource sharing.
mplsTrafficParamGroup	1.3.6.1.4.1.43.45.1.5.12.1.3.1.9			Object(s) required for supporting QoS resource reservation.
I32 mplsTrafficParamIndex	1.3.6.1.4.1.43.45.1.5.12.1.1.14.1.1	Integer32	not-accessible	Uniquely identifies this row of the table. Note that zero represents an invalid index.
I32 mplsTrafficParamIndexNext	1.3.6.1.4.1.43.45.1.5.12.1.1.13	Integer32	read-only	This object contains an appropriate value which will be used for mplsTrafficParamIndex when creating entries in the mplsTrafficParamTable. The value 0 indicates that no unassigned entries are available. To obtain the mplsTrafficParamIndex value for a new entry, the manager issues a management protocol retrieval operation to obtain the current value of this object. After each retrieval operation, the agent should modify the value to reflect the next unassigned index. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.

INT mplsXCAdminStatus	1.3.6.1.4.1.43.45.1.5.12.1.1.9.1.8	INTEGER	read-create	The desired operational status of this segment.
NTF mplsXCDown	1.3.6.1.4.1.43.45.1.5.12.1.2.0.2			This notification is generated when a mplsXCOperStatus object for one of the configured cross-connect entries is about to enter the down state from some other state (but not from the notPresent state). This other state is indicated by the included value of mplsXCOperStatus.
mplsXCEntry	1.3.6.1.4.1.43.45.1.5.12.1.1.9.1		not-accessible	A row in this table represents one cross-connect entry. The following objects index it: - cross-connect index mplsXCIndex that uniquely identifies a group of cross-connect entries - interface index of the in-segment, mplsInSegmentIfIndex - incoming label(s), mplsInSegmentLabel - out-segment index, mplsOutSegmentIndex Originating LSPs: These are represented by using the special combination of values mplsInSegmentIfIndex=0 and mplsInSegmentLabel=0 as indexes. In this case the mplsOutSegmentIndex MUST be non-zero. Terminating LSPs: These are represented by using the special value mplsOutSegmentIndex=0 as index. Special labels: Entries indexed by reserved MPLS label values 0 through 15 imply terminating LSPs and MUST have mplsOutSegmentIfIndex = 0. Note that situations where LSPs are terminated with incoming label equal to 0, should have mplsInSegmentIfIndex = 0 as well, but can be distinguished from originating LSPs because the mplsOutSegmentIfIndex = 0. The mplsOutSegmentIfIndex MUST only be set to 0 in cases of terminating LSPs. An entry can be created by a network administrator or by an SNMP agent as instructed by an MPLS signaling protocol.
mplsXCGroup	1.3.6.1.4.1.43.45.1.5.12.1.3.1.4			Collection of objects needed to implement a cross-connect entry.
