Description: L2 management MIB for D-Link DGS-3620-28SC 28-port SFP switch covering VLANs, STP, and L2 management objects.

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-L2MGMT-MIB?

This proprietary D-Link MIB defines Layer 2 network management information for the DGS-3620-28SC, a 28-port SFP Gigabit switch, covering VLAN, Spanning Tree, and other L2 switching management objects. It exposes L2 configuration and status data rather than raw traffic counters, letting an operator confirm the switch's fiber-uplink and access-port switching behavior matches design. Its monitoring value is in catching L2 topology problems, such as unexpected STP state changes or VLAN misconfiguration, on a fiber-aggregation switch where such issues can silently affect many downstream devices. 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 switches in fiber-aggregation points within campus or metro networks. Engineers can download the DGS-3620-28SC-L2MGMT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3620-28SC-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 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 membership and STP port-state tables (following the *VlanTable/*StpPortEntry naming convention typical of D-Link L2MGMT modules) to confirm fiber uplinks 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
