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

This proprietary D-Link MIB defines Layer 2 network management information for the DGS-3620-28SC-DC, a DC-powered 28-port SFP Gigabit switch aimed at telecom/central-office environments, covering VLAN, STP, and other L2 switching management features. It exposes L2 configuration and status data rather than raw traffic counters, focused on confirming the switch's switching-plane behavior. Because this model is DC-powered for carrier/telecom deployments, monitoring its L2 state (VLAN assignment, STP port state) alongside power-supply status from the base system MIB is important for verifying network topology integrity in facilities where AC power is unavailable or unreliable. It is a proprietary companion to D-Link's L3-management and resource-management MIBs for the DGS-3620 family, alongside standard bridge/STP MIB concepts. It is deployed on DGS-3620-28SC-DC switches in telecom central offices or DC-powered environments requiring fiber (SFP) uplinks and Layer 2 management. Engineers can download the DGS-3620-28SC-DC-L2MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3620-28SC-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.

Supported Devices

  • D-Link DGS-3620-28SC-DC DC-powered switch

Monitoring Examples

No sample object or table names were supplied for this module in the available excerpt, so a concrete OID example cannot be given. Conceptually an operator would poll VLAN and STP port-state tables (following the *VlanTable/*StpPortEntry naming convention typical of D-Link L2MGMT modules) to confirm the fiber uplinks and access ports maintain correct VLAN tagging and loop-free topology. This is inferred from the module's stated purpose since sample_objects were not provided.

What Can Be Monitored

  • VLAN membership state
  • spanning tree port state
  • L2 switching configuration status
