Description: Huawei MPLS extensions MIB providing additional MPLS management objects beyond standard IETF MPLS MIBs.

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 HUAWEI-MPLS-EXTEND-MIB?

HUAWEI-MPLS-EXTEND-MIB is a Huawei vendor-specific MIB (OID 1.3.6.1.4.1.2011.5.25.121) that extends the IETF MPLS-TE-STD-MIB with Huawei-proprietary objects for managing and monitoring MPLS on Huawei routers. It defines tables such as hwMplsTunnelTable (uniquely identifying tunnels via hwMplsTunnelIndex, hwMplsTunnelInstance, and ingress/egress LSR IDs, and importing mplsTunnelAdminStatus/mplsTunnelOperStatus from MPLS-TE-STD-MIB), hwStaticLspTable/hwStaticLspTnlTable for static LSP-to-tunnel mapping, and a family of Fast Reroute tables (hwTunnelFrrBypassTable, hwTunnelFrrARHopTable, hwTunnelFrrRouteDBTable) for backup path and alternate-route information, plus traffic statistics tables for tunnels and static LSPs. This makes it a control-plane and traffic-accounting extension rather than a hardware-sensor MIB, letting an operator see tunnel administrative/operational state alongside Huawei-specific FRR bypass and traffic-volume detail that standard MPLS MIBs don't expose. It depends on the standard MPLS-TE-STD-MIB for the base tunnel objects it extends. It is deployed on Huawei MPLS-capable routers (NE/CX series running VRP) in service-provider or enterprise MPLS backbones, and engineers typically get a HUAWEI-MPLS-EXTEND-MIB download from Huawei's support site to load into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-MPLS-EXTEND-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

  • Huawei NE/CX series routers (MPLS-capable, Huawei VRP platform)

Monitoring Examples

An operator polls hwMplsTunnelTable for a given tunnel's mplsTunnelOperStatus and cross-references hwTunnelFrrBypassTable; an operational tunnel with no corresponding active bypass entry during a link failure would indicate FRR protection did not engage and traffic is at risk of being dropped.

What Can Be Monitored

  • MPLS tunnel table entries (admin/oper status)
  • static LSP and tunnel-to-static-LSP mapping table entries
  • FRR bypass tunnel and backup route table entries
  • per-tunnel/per-static-LSP traffic statistics counters
  • TE-class and TE-VPN QoS table entries
