Description: L2 management MIB for D-Link DGS-3620-28TC DC-powered 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 DGS-3620-28TC-DC-L2MGMT-MIB?

This is a D-Link proprietary Layer 2 management MIB for the DGS-3620-28TC, a DC-powered managed switch in the DGS-3620 series with copper (TC) ports. It structures management information for L2 features such as VLAN configuration, Spanning Tree Protocol state, and other switching-layer settings, following the swL2-prefixed object naming convention used across D-Link's DGS-3xxx L2MGMT MIBs. As a monitoring module it is used to verify software-configured state such as VLAN membership and spanning-tree topology rather than raw hardware sensors, complementing separate system MIBs that report chassis-level uptime, power, and fan health. It relies on the switch's parallel L3MGMT and system/product MIBs for a full management picture, and conceptually parallels IEEE 802.1Q/802.1D switching standards. It is typically deployed in enterprise wiring closets where DC-powered DGS-3620-28TC switches are polled by an SNMP-based network management system. Engineers can download the DGS-3620-28TC-DC-L2MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3620-28TC-DC-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

No specific object or table names were included in the available source excerpt for this module, so exact identifiers cannot be confirmed here; based on its short description and the swL2-prefixed naming convention used in sibling D-Link L2MGMT MIBs (e.g. swL2VlanTable in DGS3627G-L2MGMT-MIB), it would expose analogous VLAN membership and STP state tables. An administrator would typically poll such tables to confirm VLAN port assignments and spanning-tree port role/state, which would reveal misconfigured trunks or a port stuck in blocking state.

What Can Be Monitored

  • VLAN configuration
  • spanning tree protocol state
  • L2 switching feature configuration
