Description: Manages Multiple Spanning Tree Protocol (MSTP) instances, port roles, and topology on H3C Layer 2 switches.

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 HH3C-LswMSTP-MIB?

This is an H3C (Hangzhou Huawei-3Com/New H3C) private MIB managing Multiple Spanning Tree Protocol (MSTP) instances, port roles, and Layer 2 topology on H3C switches, an IEEE 802.1s-based extension to spanning tree that allows multiple independent spanning tree instances mapped to VLAN groups. Although no sample objects were provided, an MSTP MIB of this kind would typically expose per-instance bridge/root priority, port role and state (e.g., designated, root, blocking, forwarding) per MST instance, and region configuration identifying which VLANs map to which instance. Its monitoring value is in Layer 2 topology software state—detecting port role/state changes that indicate a topology change, root bridge elections, or a spanning-tree loop-prevention event—rather than hardware sensor telemetry. While modeled conceptually on IEEE 802.1s MSTP and related bridge MIBs, it is implemented as an H3C private MIB rather than a direct standards MIB. It would be deployed on H3C (and rebadged HPE/3Com-lineage) Layer 2 switches in enterprise campus networks using MSTP for VLAN-aware loop prevention. Engineers can download the HH3C-LswMSTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-LswMSTP-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 Layer 2 switch

Monitoring Examples

No sample objects were provided for this MIB, so specific object names cannot be cited directly; however, based on its purpose, an operator would typically poll per-instance port state/role objects to confirm a port's expected role (e.g., root or designated) within a given MST instance, and watch for unexpected transitions to a blocking or discarding state that would indicate a topology change or physical link issue. Because MSTP maps VLAN groups to instances, monitoring here would focus on confirming the correct instance-to-VLAN mapping and stable port roles across the topology. Confirming exact object names would require consulting the actual MIB source.

What Can Be Monitored

  • MSTP instance port role/state
  • spanning tree topology changes
  • MST region/VLAN-to-instance mapping

How to Use in IPNetwork Monitor

Example using hh3cdot1sMstiStpRXStpBPDU OID:

Select an H3C Layer 2 switch (Multiple Spanning Tree Protocol) 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 hh3cdot1sMstiStpRXStpBPDU 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. The number of received Config BPDU. Effective in CIST. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
