Description: Covers Layer 3 management and routing protocols for the DC-powered D-Link DGS-3620-28SC switch.

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 DGS-3620-28SC-DC-L3MGMT-MIB?

This is a D-Link proprietary enterprise MIB module defining the Layer 3 management information structure for the DGS-3620-28SC, a DC-powered fiber (SC-port) managed switch in D-Link's DGS-3620 series. It exposes routing-related configuration and status data, including OSPF equal-cost multipath (ECMP) parameters, administrative route preference, and OSPF link-state database management objects. As a management/monitoring module it lets an administrator confirm that Layer 3 routing features such as OSPF ECMP are enabled and behaving as configured, complementing the switch's separate system MIB, which is where general hardware health (uptime, temperature, power, fans) is normally reported. It depends on the switch's companion L2 management and product/system MIBs, and conceptually parallels standard OSPF-MIB routing concepts, for a complete management picture. It is deployed in enterprise or carrier wiring closets where DC-powered DGS-3620-28SC switches provide Layer 3 routing/switching, polled via an SNMP-based network management system. Network engineers evaluating or troubleshooting this functionality can download the DGS-3620-28SC-DC-L3MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3620-28SC-DC-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-3620-28SC DC-powered Layer 3 managed switch

Monitoring Examples

An administrator polling swL3OspfECMPState can confirm whether OSPF equal-cost multipath load balancing is currently active on the switch, while swL3OspfECMPCrcHigh and swL3OspfECMPTCPorUDPport reveal the hashing parameters used to distribute flows across redundant paths. Checking swL3RoutePreference shows the administrative distance assigned to each route source, which helps explain unexpected route selection between OSPF, static, and other protocols. The swL3OspfLsdbMgmt branch groups objects for inspecting the OSPF link-state database, useful when diagnosing adjacency flaps or slow convergence.

What Can Be Monitored

  • OSPF ECMP enabled/state
  • OSPF ECMP hash parameters
  • route preference / administrative distance
  • OSPF link-state database entries

How to Use in IPNetwork Monitor

Example using swL3ospfVirtIfEvents OID:

Select a D-Link DGS-3620-28SC DC-powered Layer 3 managed switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type swL3ospfVirtIfEvents into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of state changes or error events on this Virtual Link. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
