Description: L3 management MIB for D-Link DGS-3120-24PC 24-port PoE switch covering routing, ACLs, QoS, and L3 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-3120-24PC-L3MGMT-MIB?

DGS-3120-24PC-L3MGMT-MIB is D-Link's Layer 3 management MIB for the DGS-3120-24PC, a 24-port Gigabit PoE switch, covering IP routing, access control lists (ACLs), QoS, and other Layer 3 management features for this PoE-capable model. It exposes routing configuration (IP interfaces, routing table entries), ACL rules, and QoS policy data layered on top of the switch's PoE port capabilities. For monitoring hardware/software status, this MIB is relevant for confirming routed interfaces remain up and correctly addressed, verifying ACL/QoS policies haven't drifted from intended configuration, and, in combination with the switch's PoE capability, tracking that powered endpoint devices continue receiving expected power alongside Layer 3 connectivity. It is a vendor-specific enterprise MIB built on standard IP routing/IP-MIB and ACL concepts. It is typically deployed in mid-sized enterprise networks as a PoE access/aggregation switch providing inter-VLAN routing to powered endpoints like IP phones or wireless access points, where DGS-3120-24PC-L3MGMT-MIB SNMP monitoring verifies both routed connectivity and applied ACL/QoS policy.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3120-24PC-L3MGMT-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 objects were captured for this module, but consistent with its Layer 3/PoE scope, an admin would typically poll IP interface tables to confirm each routed VLAN interface remains up with the expected address, and check ACL rule counters to confirm traffic filtering policies are being applied as intended. PoE port status objects (implied by the device's PC/PoE model designation, though not captured in the sample list) would typically be checked to confirm powered endpoints are receiving power correctly. A missing routed interface or unexpectedly dropped ACL match count would flag a Layer 3 or policy misconfiguration.

What Can Be Monitored

IP interface status and addressing
routing table entries
ACL rule configuration and hit counts
QoS policy configuration
PoE port power delivery
