What Is RFC1271-TRAPS?
RFC1271-TRAPS defines the notification (trap) companion for the original Remote Network Monitoring (RMON) MIB specified in RFC 1271, covering the alarm/event mechanism used by RMON probes. It defines the rising-threshold and falling-threshold trap notifications that an RMON agent sends when a monitored statistic crosses an administrator-configured boundary. Rather than exposing polled data itself, it is the alerting layer for RMON-based monitoring: it lets a network management station be proactively notified of software/traffic-level conditions -- such as an error-rate or utilization counter breaching a threshold -- without continuous polling, complementing the counters defined in the base RMON MIB rather than any hardware sensors. It is entirely dependent on, and only meaningful alongside, the base RMON MIB (RFC 1271) alarm and event tables that define the thresholds these traps report against. It is used wherever RMON probes or RMON-capable switch/router agents are deployed to provide threshold-crossing alerts for network traffic monitoring. Engineers implementing or auditing this functionality typically reference the RFC1271-TRAPS RFC/standard documentation for the authoritative specification.
IPNetwork Monitor allows you to monitor SNMP objects defined in RFC1271-TRAPS. 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.
What Can Be Monitored
- rising-threshold trap events
- falling-threshold trap events
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- RMON-capable switches, routers, and standalone RMON probes
Monitoring Examples
This module defines only the RMON rising-threshold and falling-threshold trap notifications themselves rather than data-bearing tables; an administrator who configures an RMON alarm entry against, for example, an interface error counter would receive one of these traps when the counter's value crosses the configured rising or falling threshold, but as a notifications-only module it has no pollable runtime data objects of its own to describe a polling scenario for.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| NTF risingAlarm | 1.3.6.1.2.1.16.0.1 | The SNMP trap that is generated when an alarm entry crosses its rising threshold and generates an event that is configured for sending SNMP traps. | ||
| NTF fallingAlarm | 1.3.6.1.2.1.16.0.2 | The SNMP trap that is generated when an alarm entry crosses its fallingthreshold and generates an event that is configured for sending SNMP traps. | ||
| NTF packetMatch | 1.3.6.1.2.1.16.0.3 | The SNMP trap that is generated when a packet is captured by a channel that is configured for sending SNMP traps. |
