Description: L3 management MIB for D-Link DGS-3120-24SC 24-port SFP switch covering routing protocols, ACLs, and L3 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-3120-24SC-L3MGMT-MIB?

DGS-3120-24SC-L3MGMT-MIB is a D-Link enterprise MIB providing Layer 3 management for the DGS-3120-24SC 24-port SFP switch, rooted under swL3MgmtMIB (imported from the SWDGS3120PRIMGMT-MIB product tree). Its swL3IpCtrlTable exposes per-IP-interface configuration including IPv4/IPv6 admin state (swL3IpCtrlIpv4AdminState, swL3IpCtrlIpv6AdminState), proxy ARP and local proxy ARP settings, DHCPv6 client state, and DHCP option-12 host-name behavior, while swL3IpStaticRouteTable models static routing entries (destination, mask, next hop, metric, weight, backup state, and row status) for IPv4 routing on the switch. Together these tables reveal the device's Layer 3 interface and routing configuration state — whether IP interfaces are administratively up and whether static routes are active and correctly weighted — which is central to diagnosing routing and reachability problems on this switch. It depends on the vendor's broader SWDGS3120PRIMGMT-MIB OID tree for its module placement and is deployed specifically on DGS-3120-24SC hardware acting as a Layer 3 aggregation/access switch. Administrators managing this model typically keep the DGS-3120-24SC-L3MGMT-MIB MIB Browser tree open when auditing static routes.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS-3120-24SC-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

An operator polls swL3IpStaticRouteTable to review swL3IpStaticRouteNextHop and swL3IpStaticRouteMetric for a given swL3IpStaticRouteDest/Mask pair, checking swL3IpStaticRouteStatus and swL3IpStaticRouteBkupState; a route status other than active combined with an unreachable next hop would indicate a static route has failed over or is misconfigured, explaining a loss of reachability to that destination network.

What Can Be Monitored

IP interface admin state (IPv4/IPv6)
proxy ARP and DHCPv6 client configuration
static route destination/next-hop/metric entries
static route row status and backup state
DHCP option-12 host-name settings
