Description: Manages IP layer configuration and statistics including routing, interfaces, and address management on D-Link 3100 series switches.

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 DLINK-3100-IP?

This is a D-Link enterprise MIB for the 3100 series switch that manages IP-layer configuration and statistics, including address assignment, routing, and related protocol references such as ICMP, RIPv2, and ARP. It exposes an IP address table describing each interface's IP address, subnet mask, broadcast handling, backup address, and administrative status, extending the standard IP MIB model with D-Link-specific fields. Its monitoring focus is IP-layer configuration and operational status: verifying which addresses are assigned to which interfaces, whether an interface is administratively up, and whether backup/failover addressing is configured, which helps detect IP misconfiguration or failover issues rather than deep hardware faults. It closely parallels and depends on the standard IETF IP-MIB address table model, while also referencing companion protocol MIBs for ICMP, RIPv2, and ARP. It is typically deployed on D-Link 3100 series switches functioning as Layer 3-capable devices where IP interface configuration and basic routing/ARP visibility are needed via SNMP. Engineers can download the DLINK-3100-IP file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINK-3100-IP. 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 3100 series switch

Monitoring Examples

An administrator can poll rsIpAddrTable/rsIpAddrEntry, keyed by rsIpAdEntAddr, to read rsIpAdEntIfIndex, rsIpAdEntNetMask, and rsIpAdEntAdminStatus for each configured IP address, confirming an interface is administratively up and correctly subnetted. rsIpAdEntBackupAddr and rsIpAdEntBcastAddr can be checked to verify failover addressing and broadcast handling are configured as intended, while rsIpAdEntArpServer indicates whether the interface is designated to answer ARP requests on behalf of the address, useful for diagnosing an ARP resolution failure.

What Can Be Monitored

IP address to interface mapping
subnet mask per address
interface administrative status
backup/failover IP address
ARP server designation per address

How to Use in IPNetwork Monitor

Example using rsArpRequestsSent OID:

Select a D-Link 3100 series switch (DES/DGS-3100), IP-layer configuration as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type rsArpRequestsSent into the Find box to locate it in the OID tree, then select it and click OK. Displays how many ARP requests have been sent out to an ARP server for address resolution. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
