Description: H3C MIB for loopback detection managing loop detection and blocking to prevent broadcast storms in switched networks.
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 H3C-LPBKDT-MIB?
H3C-LPBKDT-MIB is an H3C Technologies Co., Ltd. proprietary MIB implementing loopback detection, which identifies and mitigates Layer 2 loops (a common cause of broadcast storms) on H3C switches. Its notifications cover port-loopback-detected and port-loopback-recovered events, and per-VLAN variants of the same, alongside a VLAN-ID varbind object. As a notification MIB it lets an administrator get alerted the moment a switch detects (and later clears) a Layer 2 loop, including which VLAN was affected. It is deployed on H3C Technologies managed switches. Engineers can download the H3C-LPBKDT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-LPBKDT-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 Technologies managed switches
Monitoring Examples
An administrator receives an h3cLpbkdtTrapPerVlanLoopbacked notification and reads h3cLpbkdtVlanID to identify which VLAN has a Layer 2 loop on an H3C switch.
What Can Be Monitored
- loopback detection and recovery events per port/VLAN
