Description: Huawei switch service resource trap MIB defining notifications for hardware resource exhaustion and table overflow events.
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 HUAWEI-SWITCH-SRV-RES-TRAP-MIB?
HUAWEI-SWITCH-SRV-RES-TRAP-MIB is a Huawei switch MIB dedicated to defining alarm notifications for forwarding-engine resource overload, per its module description covering 'alarm information of forwarding engine resource overload.' It is fault/notification-focused rather than a source of pollable runtime tables, defining traps rather than a set of counters an operator would periodically read. Its monitoring value is squarely hardware-capacity health: it alerts when a switch's forwarding-engine hardware resource, such as a MAC address table, ARP table, or route table, approaches or exceeds its physical capacity, a condition that otherwise causes silent packet drops or flooding. It complements Huawei's entity and forwarding-resource MIBs, which would expose the underlying table-size counters this module's traps are triggered by. It is deployed on Huawei switches, particularly in campus or data-center networks operating near forwarding-table scale limits, and administrators can download the HUAWEI-SWITCH-SRV-RES-TRAP-MIB file to load into their trap receiver or MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-SWITCH-SRV-RES-TRAP-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
- Huawei switches (campus and data-center)
Monitoring Examples
No sample object names were provided, and the module description indicates this MIB is primarily a trap/notification definition rather than a set of pollable counters. Rather than periodic polling, an operator would rely on receiving one of its defined traps, which fires when a switch's forwarding-engine resource (such as a MAC or routing table) approaches or hits capacity, indicating the switch needs additional table space freed up or a hardware/software limit has been reached.
What Can Be Monitored
- forwarding-engine resource overload alerts
- table (MAC/ARP/route) overflow notifications
- resource exhaustion severity
- affected board/card identification
