HH3C-LPBKDT-MIB

Description: Manages loopback detection on H3C switch ports to identify and disable ports causing Layer 2 loops.

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.

HH3C-LPBKDT-MIB implements loopback detection on H3C switches, a feature that identifies Layer 2 loops on access ports (often caused by misconfigured cabling) and shuts them down to prevent broadcast storms. It exposes per-VLAN loopback-detection configuration and a notification framework signaling when a loop is detected on a port. Its monitoring value is fault-oriented: receiving traps when a port is identified as looped and consequently blocked, flagging a network-integrity fault rather than a raw performance metric. It works in conjunction with standard bridge/spanning-tree concepts (IEEE 802.1D) even though loopback detection itself is a proprietary H3C mechanism. It is deployed on H3C access-layer switches in enterprise LANs to catch accidental physical loops before they cause broadcast storms. Engineers can download the HH3C-LPBKDT-MIB file directly to load it into their MIB browser.

hh3cLpbkdtVlanID identifies which VLAN loopback detection is monitoring, and hh3cLpbkdtNotifications/hh3cLpbkdtObjects define the trap sent (prefixed by hh3cLpbkdtTrapPrefix) when a loop is detected on a port. An admin receiving one of these traps would immediately check the flagged port for a bad cable or unintended switch-to-switch loopback connection causing broadcast storm risk.

Detects network loops on interfaces and VLANs to prevent broadcast storms on H3C switches.
