Description: Manages Rapid Spanning Tree Protocol (RSTP) port states, edge ports, and topology changes 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 HH3C-LswRSTP-MIB?

HH3C-LswRSTP-MIB is an H3C vendor MIB implementing management objects for Rapid Spanning Tree Protocol (RSTP) on H3C Layer 2 switches. It exposes per-port and per-bridge data such as port role, port state, edge-port designation, and topology-change event counts, extending the standard bridge/spanning-tree data model with H3C-specific detail. Operationally it is used to monitor the software health of the Layer 2 topology: a port stuck in a non-forwarding state, frequent topology-change notifications, or an edge port flapping all indicate network instability or a misconfigured/failing link. It works alongside the IETF BRIDGE-MIB and P-BRIDGE/Q-BRIDGE MIBs which define the base spanning-tree object model that RSTP extends. It is deployed on H3C campus and enterprise Layer 2 switches forming redundant Ethernet topologies where fast convergence after a link failure is required. Engineers can download the HH3C-LswRSTP-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

No specific object names were supplied in the source for this MIB, so concrete OIDs cannot be cited, but a network engineer would typically poll per-port RSTP role/state (root, designated, alternate, forwarding, discarding) and topology-change counters to verify the ring or tree has converged. A port that remains in discarding state longer than expected, or a rapidly incrementing topology-change counter, signals a flapping link or a spanning-tree misconfiguration.

What Can Be Monitored

per-port RSTP role and state
edge-port designation
topology-change count
port forwarding/discarding status

How to Use in IPNetwork Monitor

Example using hh3cdot1dStpRXStpBPDU OID:

Select an H3C Layer 2 switch (Rapid 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 hh3cdot1dStpRXStpBPDU 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.
