Description: L2 management MIB for D-Link DGS-3627G Gigabit switch covering VLANs, STP, and L2 management features.

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 DGS3627G-L2MGMT-MIB?

This is a D-Link proprietary Layer 2 management MIB for the DGS-3627G, a Gigabit managed switch, covering VLANs, Spanning Tree Protocol, and other L2 switching features. It provides a particularly detailed VLAN table exposing membership, static and dynamic tagged/untagged port assignment, forbidden ports, current (learned) tagged/untagged ports, and GVRP advertisement state. As a monitoring module it is used to verify that VLAN membership actually matches the intended static configuration versus what has been dynamically learned, which is a common source of Layer 2 misconfiguration or unauthorized access on a switch. It depends on the switch's companion L3MGMT and system/product MIBs for a complete management picture, and directly parallels IEEE 802.1Q VLAN and GVRP standards. It is deployed in enterprise wiring closets where DGS-3627G Gigabit switches are managed via an SNMP-based NMS. Engineers can download the DGS3627G-L2MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS3627G-L2MGMT-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.

Monitoring Examples

An administrator polling swL2VlanTable entries -- swL2VlanIndex, swL2VlanName, and swL2VlanMemberPorts -- can enumerate configured VLANs and their expected port membership, while comparing swL2VlanStaticTaggedPorts and swL2VlanStaticUntaggedPorts-style static config against swL2VlanCurrentTaggedPorts and swL2VlanCurrentUntaggedPorts reveals any discrepancy introduced by dynamic (GVRP) learning. Checking swL2VlanForbiddenPorts confirms that ports meant to be excluded from a VLAN haven't somehow joined it, and swL2VlanAdvertisementState shows whether GVRP advertisement is enabled on a given VLAN -- useful when a port unexpectedly appears in a VLAN it shouldn't be part of.

What Can Be Monitored

  • VLAN membership (static vs. current/learned)
  • tagged vs. untagged port assignment
  • forbidden ports per VLAN
  • GVRP advertisement state
  • VLAN type (static/dynamic)

How to Use in IPNetwork Monitor

Example using swL2PortBufferFullDrops OID:

Select a D-Link DGS-3627G Gigabit 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 swL2PortBufferFullDrops 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 total number of packets discarded while buffer full. 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.
