What Is DES3028G-L2MGMT-MIB?

DES3028G-L2MGMT-MIB is a vendor-specific D-Link MIB (swL2MgmtMIB) that provides comprehensive Layer 2 switch management for the DES-3028G stackable Fast Ethernet switch family. It's organized into sub-trees covering device control (Telnet/Web access state, device alarms), port management (cable diagnostics, port mirroring, port security bindings), QoS (802.1p priority and RADIUS-assigned bandwidth/priority), trunking and VLAN management, IGMP snooping (multicast VLAN and group tables, dynamic IP multicast), DHCP relay, loop detection (with per-port loop-occurred/restart tracking), and flood-MAC detection for identifying MAC addresses causing broadcast storms. Given its scope, it exposes a large set of configuration and status tables spanning per-feature enable/disable controls, per-port operational state, and notification traps for security or loop events. Monitoring it lets operators verify that L2 protective features — loop detection, port security, IGMP snooping — are active and correctly triggering, and administrators can download the DES3028G-L2MGMT-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DES3028G-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 DES-3028G (and related DES-30xx series) stackable Layer 2 switches

Monitoring Examples

An operator polls the loop-detect port table for loop-occurred flags after enabling loop detection; a port that repeatedly shows a loop occurred and needs a restart invoked would indicate a physical wiring loop or misconfigured redundant link causing broadcast storms on that segment.

What Can Be Monitored

  • device Telnet/Web management access state
  • port mirroring and cable diagnostics status
  • port security bindings and violations
  • IGMP snooping multicast VLAN/group table entries
  • loop detection occurrence/restart per port
  • flood-MAC detection events
