What Is BPDU-TUNNELING-MIB?
BPDU-TUNNELING-MIB is a proprietary enterprise MIB for configuring 802.1D BPDU (Bridge Protocol Data Unit) tunneling, a feature that lets a provider network transparently carry customer spanning-tree PDUs across it without participating in the customer's spanning tree. No object list is available in this excerpt, but conceptually the module would expose per-port or per-VLAN enable/disable configuration for BPDU tunneling. Monitoring this feature is about network topology/configuration correctness rather than classic hardware health: confirming BPDU tunneling is enabled where expected on provider-edge ports helps avoid customer spanning-tree loops or unintended spanning-tree convergence events across the provider network. It directly depends on, and interacts with, the standard 802.1D bridge/spanning-tree MIB concepts, since it is specifically about tunneling those PDUs rather than processing them. It is typically deployed on provider-edge switches at the boundary between a service provider's network and customer sites using a transparent LAN/Ethernet service. Network engineers evaluating or troubleshooting this functionality can download the BPDU-TUNNELING-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in BPDU-TUNNELING-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
- provider-edge switches (vendor-specific, likely enterprise switch/bridge platforms)
Monitoring Examples
No sample objects were available for this module in the source, so specific object or table names cannot be confirmed. Based on its stated purpose, an administrator would check per-port BPDU-tunneling enable status to confirm STP frames from a customer site are being tunneled rather than processed locally, which matters when diagnosing an unexpected spanning-tree topology change on the provider network.
What Can Be Monitored
- per-port BPDU tunneling enable status
