HH3C-LswTRAP-MIB

Description: Defines SNMP trap notifications for Layer 2 switch events including port state and MAC changes on H3C devices.

HH3C-LswTRAP-MIB is an H3C enterprise MIB that defines SNMP trap (notification) objects for Layer 2 switch events, such as port link state transitions and MAC address table changes, on H3C switching platforms. Rather than exposing pollable configuration or performance tables, it is a notification-definition module whose purpose is to standardize the varbinds and trap OIDs sent when specific switch-level events occur. Its monitoring value is fault/event-driven: it lets a network management station receive asynchronous alerts about port state changes or MAC learning events instead of requiring continuous polling, which is useful for near-real-time fault detection on access switches. It depends on standard interface indexing conventions (IF-MIB ifIndex) to identify which port an event pertains to, even though the specific trap objects weren't captured in this entry. It is typically deployed on H3C Layer 2 switches feeding an SNMP trap receiver or NMS, where HH3C-LswTRAP-MIB SNMP monitoring enables event correlation and alerting.

No sample objects were captured for this module, so specific trap names cannot be confirmed from the source. Based on its description, an admin would configure a trap receiver to catch port up/down and MAC address change notifications from this MIB, using them to detect flapping links or unauthorized MAC learning on access ports. Without the underlying object list, exact varbind names are not stated here.
