Description: L3 management MIB for D-Link DGS-3426 switch covering routing protocols, ACLs, VRRP, and Layer 3 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 DGS3426-L3MGMT-MIB?

DGS3426-L3MGMT-MIB is a vendor-specific MIB from D-Link scoped to Layer 3 management on the DGS-3426 switch, covering routing-protocol control, IP interface configuration, ARP/FDB information, static routing, and IPv6 interface settings. Its swL3IpCtrlTable configures per-interface objects such as swL3IpCtrlIpAddr/IpSubnetMask, swL3IpCtrlVlanName, swL3IpCtrlProxyArp, and swL3IpCtrlAdminState, with a parallel swL3Ipv6CtrlTable and swL3Ipv6AddressCtrlTable handling IPv6 router-advertisement timers and address lifetimes, plus DHCPv6 prefix-delegation objects. A swL3IpFdbInfoTable exposes the Layer 3 forwarding-database entries (IP address, subnet mask, port, entry type) learned or configured on the switch, and swL3IpStaticRouteTable manages static routes with destination, mask, next hop, metric, and RowStatus-based lifecycle control, alongside a top-level swL3DevCtrlRIPState scalar for enabling RIP. This makes it a broad Layer 3 configuration/state MIB useful for confirming IP interface, static-route, and RIP configuration match intent on a routing-capable D-Link switch. The DGS3426-L3MGMT-MIB MIB is deployed on D-Link DGS-3426 Layer 3 switches in campus/enterprise networks.

IPNetwork Monitor allows you to monitor SNMP objects defined in DGS3426-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.

Supported Devices

  • D-Link DGS-3426 Layer 3 switches

Monitoring Examples

An operator walks swL3IpStaticRouteTable to confirm a critical static route's swL3IpStaticRouteStatus is active and its swL3IpStaticRouteNextHop matches the intended gateway; a route present with swL3IpStaticRouteStatus showing notInService would explain traffic silently falling back to a default route or being blackholed.

What Can Be Monitored

  • per-interface IP address/subnet/VLAN configuration
  • IPv6 interface and address lifetime configuration
  • Layer 3 forwarding-database (ARP/FDB) entries
  • static route table entries and status
  • RIP protocol admin state
