What Is DGS3427-L3MGMT-MIB?

DGS3427-L3MGMT-MIB is a vendor-specific D-Link MIB structuring Layer 3 network management information for the DGS-3427 switch, an enterprise Layer 3 switch supporting routing protocols such as OSPF and VRRP. It exposes routing-related configuration such as route preference values alongside the switch's broader routing, OSPF, and VRRP feature set, covering how routes are selected and how redundancy is managed. Its monitoring focus is on software/configuration status of the routing engine -- for example confirming route preference/administrative distance settings -- rather than physical hardware telemetry. As an L3 management umbrella MIB it depends on/parallels standard routing MIBs (OSPF-MIB, VRRP MIB conventions) for the actual protocol state. It is deployed by network administrators running D-Link DGS-3427 switches as Layer 3 distribution/core switches in enterprise campus networks. Engineers can download the DGS3427-L3MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS3427-L3MGMT-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

  • D-Link DGS-3427 Layer 3 switch

Monitoring Examples

An administrator would check swL3RoutePreference to confirm the administrative distance/preference assigned to a routing source (e.g., static vs OSPF vs VRRP-derived routes) on the DGS-3427, ensuring the switch prefers the intended route source when multiple paths are available. An unexpectedly changed preference value could reveal a misconfiguration causing the switch to select a suboptimal or backup route as primary.

What Can Be Monitored

  • route preference/administrative distance
  • OSPF routing status
  • VRRP redundancy status
  • Layer 3 routing configuration
