Description: L2 management MIB for D-Link DGS-3620-28TC 28-port combo switch covering VLANs, STP, LACP, and L2 management.

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-L2MGMT-MIB?

This proprietary D-Link MIB defines Layer 2 network management information for the DGS-3620-28TC, a 28-port combo (copper/SFP) Gigabit switch, covering VLANs, Spanning Tree Protocol, Link Aggregation (LACP), and other L2 switching management features. It exposes L2 configuration and status state rather than raw counters, allowing verification of the switch's switching-plane behavior including aggregated-link health. Its monitoring value includes confirming LACP link-aggregation group member status alongside STP port state and VLAN assignment, which is important for detecting a failed or flapping member link within an aggregated trunk that could otherwise silently reduce available bandwidth. It is a proprietary companion to D-Link's L3-management and resource-management MIBs for the DGS-3620 family, alongside standard bridge/STP/LACP MIB concepts (IEEE 802.1AX). It is deployed on DGS-3620-28TC switches in campus distribution layers using combo ports and link aggregation for uplink resiliency, and network engineers often inspect its object tree with a DGS-3620-28TC-L2MGMT-MIB MIB Browser before scripting automated polling.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3620-28TC-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 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 LACP aggregation-group and member-port tables alongside VLAN/STP tables (following the *LacpTable/*VlanTable naming pattern typical of D-Link L2MGMT modules) to confirm all expected member links are active within a trunk. 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
  • LACP link aggregation status
  • L2 switching configuration status
