What Is DGS-3620-28PC-L3MGMT-MIB?

DGS-3620-28PC-L3MGMT-MIB is D-Link's vendor-specific Layer 3 management MIB for the DGS-3620-28PC PoE managed switch, covering Layer 3 routing features including OSPF, multicast, and route-preference configuration on top of the switch's base management framework. It exposes routing-protocol configuration and state data, including OSPF equal-cost multipath (ECMP) parameters, route preference settings, and related L3 routing objects, rather than hardware sensor data. Its monitoring value centers on software/routing status: objects like swL3OspfECMPState and swL3OspfECMPCrcHigh/TCPorUDPport let an operator confirm OSPF ECMP load-balancing is functioning as configured, and swL3RoutePreference reveals which routing source takes precedence, useful for diagnosing unexpected routing behavior. As an L3 management extension it builds on the switch's base L2/L3 MIB framework and standard OSPF concepts even though direct import is not shown in this excerpt. It is typically deployed in enterprise or campus network closets where DGS-3620-28PC PoE switches perform Layer 3 routing/OSPF alongside PoE-powered access-layer connectivity, and network engineers can download the DGS-3620-28PC-L3MGMT-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3620-28PC-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-3620-28PC PoE Layer 3 managed switch

Monitoring Examples

An admin would check swL3OspfECMPState to confirm OSPF equal-cost multipath is enabled and swL3OspfECMPCrcHigh/swL3OspfECMPTCPorUDPport to see how ECMP load-balancing hashes traffic across links, useful when troubleshooting uneven traffic distribution. swL3RoutePreference lets the operator verify which routing protocol's routes are preferred when multiple sources offer a route to the same destination, helpful when diagnosing an unexpected route selection. The commented-out swL3OspfLsdbMgmt object hints at an OSPF link-state database management capability present in this MIB branch.

What Can Be Monitored

  • OSPF ECMP state
  • OSPF ECMP hash parameters
  • L3 route preference/source

How to Use in IPNetwork Monitor

Example using swL3ospfVirtIfEvents OID:

Select a D-Link DGS-3620-28PC PoE 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.
