What Is DES-3810-28-L3MGMT-MIB?

DES-3810-28-L3MGMT-MIB is a D-Link enterprise MIB for the DES-3810-28 switch, covering Layer 3 routing management including static routes, IP interfaces, and OSPF-related equal-cost multipath (ECMP) tuning. It exposes configuration objects controlling route preference, OSPF ECMP load-balancing behavior (such as hashing on TCP/UDP port), and OSPF link-state database management, alongside default information origination settings. Its monitoring relevance is mainly configuration/software status for the routing control plane: an operator can check swL3RoutePreference and swL3OspfECMPState to confirm how the switch is balancing traffic across equal-cost OSPF paths and verify default-route origination behavior via swL3OspfDefInfoOrigMgmt, which affects how traffic is forwarded when multiple paths exist. It layers vendor-specific OSPF ECMP extensions on top of the standard OSPF protocol (as defined in the IETF OSPF-MIB) that it depends on for base routing functionality. It is typically deployed on D-Link DES-3810-28 Layer 3 managed switches in campus or SMB networks running OSPF with multiple equal-cost paths. Engineers can download the DES-3810-28-L3MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DES-3810-28-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 DES-3810-28 Layer 3 managed switch

Monitoring Examples

An operator would check swL3OspfECMPState to confirm OSPF ECMP load balancing is enabled, and swL3OspfECMPTCPorUDPport / swL3OspfECMPCrcHigh (noted with a leading comment marker in this MIB, suggesting deprecated or vendor-internal objects) to understand the hashing method used to distribute flows across equal-cost paths. swL3RoutePreference would be checked when static and OSPF routes to the same destination coexist, to confirm which source wins, and swL3OspfDefInfoOrigMgmt would be checked to verify whether the switch is originating a default route into OSPF as intended.

What Can Be Monitored

  • OSPF ECMP load-balancing state and hash method
  • route preference between static and OSPF routes
  • OSPF default-route origination setting
  • OSPF link-state database management state

How to Use in IPNetwork Monitor

Example using swL3ospfVirtIfEvents OID:

Select a D-Link DES-3810-28 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.
