What Is A3COM-HUAWEI-LswTRAP-MIB?
A3COM-HUAWEI-LswTRAP-MIB is a joint 3Com/Huawei (H3C) proprietary MIB defining SNMP trap notifications for LAN switch (Lsw) products from the former 3Com-Huawei joint venture. It focuses entirely on fault and event notification rather than polled configuration data, generating traps for events such as link state changes, port error conditions, and device-level alarm conditions. Its monitoring value is squarely in fault/status monitoring: it lets an NMS learn in near-real-time about port-level link flaps or errors and broader device alarms, which can reflect underlying hardware issues (e.g., a failing port or module) or software-detected fault conditions. It is a proprietary vendor MIB that complements standard trap conventions from SNMPv2-MIB and would typically accompany the vendor's own LAN switch object/config MIBs for the same device line. It is deployed on 3Com/H3C (and later HPE-branded) enterprise LAN switches to provide real-time fault alerting to network management systems. Network engineers evaluating or troubleshooting this functionality can download the A3COM-HUAWEI-LswTRAP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-LswTRAP-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
- 3Com/Huawei (H3C) enterprise LAN switches
Monitoring Examples
An NMS would register to receive the traps defined in this MIB to be alerted immediately when a monitored switch reports a link state change (up/down) on a port, a port error condition, or a device-level alarm, without needing to continuously poll port status. Such traps let operators react quickly to a flapping or failed port instead of discovering it only on the next scheduled poll, though the module itself defines no polled data objects to query interface counters directly.
What Can Be Monitored
- port link up/down events
- port error trap events
- device-level alarm conditions
