Description: Covers IP interface features and L3 routing on the D-Link DES-3200-52 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 DES3200-52-L3MGMT-MIB?

DES3200-52-L3MGMT-MIB is a D-Link enterprise MIB providing Layer 3 network management for the DES-3200-52 switch, covering routing protocol configuration and IP interface management, including DVMRP multicast routing and OSPF-related parameters. It exposes per-interface DVMRP configuration and counters (local address, metric, probe interval, neighbor timeout, bad packets/routes received) along with OSPF equal-cost multipath and route-preference settings. This MIB supports monitoring the software/routing-protocol health of the switch: rising DVMRP bad-packet or bad-route counters indicate multicast routing problems or misconfigured neighbors, while route-preference and ECMP settings reveal how the switch is making Layer 3 forwarding decisions, all without touching chassis hardware sensors. It layers D-Link-proprietary Layer 3 objects on top of standard routing concepts defined by DVMRP (RFC 1075) and OSPF (RFC 2328), rather than reusing the IETF's own OSPF-MIB/DVMRP-MIB directly. It is deployed on D-Link DES-3200-52 access/aggregation switches configured for Layer 3 multicast or dynamic routing in small-to-midsize enterprise networks. Engineers can download the DES3200-52-L3MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DES3200-52-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-3200-52 switch

Monitoring Examples

An admin would walk swL3dvmrpInterfaceTable/swL3dvmrpInterfaceEntry keyed by swL3dvmrpInterfaceIfIndex to check swL3dvmrpInterfaceRcvBadPkts and swL3dvmrpInterfaceRcvBadRoutes for signs of multicast routing trouble on an interface, alongside swL3dvmrpInterfaceNbrTimeout to confirm neighbor liveness detection is configured as expected. Checking swL3RoutePreference and swL3OspfECMPCrcHigh/swL3OspfECMPTCPorUDPport would reveal how the switch is load-balancing OSPF ECMP routes by transport port hash, useful when diagnosing uneven traffic distribution across equal-cost paths.

What Can Be Monitored

  • DVMRP interface configuration and neighbor timeout
  • DVMRP bad packet/route counters
  • OSPF ECMP hash settings
  • route preference configuration

How to Use in IPNetwork Monitor

Example using swL3ospfVirtIfEvents OID:

Select a D-Link DES-3200-52 switch (L3 routing) 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.
