Description: Manages Rapid Spanning Tree Protocol (RSTP) port states, edge-port configuration, and topology on H3C 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 A3COM-HUAWEI-LswRSTP-MIB?

A3COM-HUAWEI-LswRSTP-MIB is a joint 3Com/Huawei ("H3C") switch MIB managing Rapid Spanning Tree Protocol (RSTP) on their LAN switch ("Lsw") product lines, covering per-port RSTP role/state, edge-port configuration, and overall spanning-tree topology per its short description. It belongs to the Layer-2 loop-prevention/spanning-tree management category. Its monitoring value is on software/protocol status: per-port RSTP state (for example discarding/learning/forwarding) and edge-port designation reveal whether the switch's topology is stable, while topology-change counters/events would indicate network instability such as flapping links or an unexpected root-bridge change. It builds on and extends the standard IEEE 802.1w RSTP concepts and typically complements the vendor-neutral IETF/IEEE BRIDGE-MIB and P-BRIDGE/Q-BRIDGE MIBs for full bridge management context. It is deployed on H3C (3Com/Huawei joint-venture, later HPE-owned H3C) LAN switches in enterprise campus networks requiring fast Layer-2 loop convergence, and an A3COM-HUAWEI-LswRSTP-MIB download is available for administrators who need to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-LswRSTP-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/Huawei) LAN switches

Monitoring Examples

No module description or sample object list is available for this specific entry, so exact object names cannot be confirmed. Based on its documented purpose, an administrator would typically poll per-port RSTP role/state and edge-port configuration objects to confirm a port has converged to the forwarding state, investigating a port stuck in discarding/learning as a likely topology-change or misconfiguration issue, but no concrete OIDs are available for this entry.

What Can Be Monitored

per-port RSTP role and state
edge-port configuration
spanning-tree topology-change events
root bridge identity

How to Use in IPNetwork Monitor

Example using hwdot1dStpRXStpBPDU OID:

Select an H3C/3Com LAN switch 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 hwdot1dStpRXStpBPDU 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. It reports the number of STP BPDU received. 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.
