Description: L3 management MIB for D-Link DGS-3650 switch covering routing protocols, ACLs, VRRP, and Layer 3 management.

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 DGS3650-SWL3MGMT-MIB?

DGS3650-SWL3MGMT-MIB is a D-Link vendor-specific MIB providing Layer 3 network management for the DGS-3650 switch family, registered under the dgs3650 enterprise subtree (SW36XXPRIMGMT-MIB). It covers protocol enable/disable state for RIP, OSPF, VRRP, and DVMRP via swL3DevCtrlRIPState/OSPFState/VRRPState/DVMRPState, DHCP and DNS relay configuration under swL3RelayDhcpMgmt and swL3RelayDnsMgmt (including DHCP Option 82 handling), and OSPF-specific tables such as swL3OspfHostTable and swL3ospfVirtIfTable for host routes and virtual-link interface parameters, built on textual conventions imported from OSPF-MIB (TOSType, AreaID, RouterID). It also defines VRRP operational objects under swL3VrrpOperMgmt for virtual router redundancy state. Because it spans multiple Layer 3 routing protocols and relay services in one module, monitoring it is useful for confirming which routing protocols and relay agents are active and correctly configured on the switch. It depends on OSPF-MIB and IF-MIB for shared types and ifIndex binding, and is deployed on D-Link DGS-3650 series Layer 3 switches. Network teams managing these switches often download the DGS3650-SWL3MGMT-MIB file to load it into their MIB browser alongside the standard OSPF-MIB.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS3650-SWL3MGMT-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-3650 series Layer 3 switches

Monitoring Examples

An operator polls swL3DevCtrlOSPFState and swL3DevCtrlVRRPState to confirm which Layer 3 protocols are enabled, then checks swL3ospfVirtIfState in swL3ospfVirtIfTable for a configured virtual link; a virtual interface stuck in a down state despite swL3DevCtrlOSPFState showing enabled would indicate an OSPF virtual-link misconfiguration between areas.

What Can Be Monitored

  • RIP/OSPF/VRRP/DVMRP protocol enable state
  • DHCP/DNS relay configuration and Option 82 settings
  • OSPF host route and virtual interface tables
  • VRRP virtual router operational state
  • ARP aging timer configuration

How to Use in IPNetwork Monitor

Example using swL3ospfVirtIfEvents OID:

Select a D-Link DGS-3650 series Layer 3 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.
