Description: Provides core device management objects for configuration, status, and control of 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-rndMng?

This is the core general device-management MIB for D-Link 3100 series switches under the 'RND' private branch, covering fundamental system identity, action/control commands, file operations, SNMP version support, and CPU utilization. It exposes a broad mix of configuration objects (rndSysId, rndAction, rndFileName), protocol-support metadata (rlSnmpVersionSupported, rlSnmpMibVersion), and genuine performance data (rlCpuUtilDuringLastSecond/Minute/5Minutes). It is explicitly useful for monitoring hardware/software status because it directly reports CPU load over multiple time windows and supports controlled reboot operations (rlRebootDelay), making it a primary go-to MIB for basic health checks on these switches. It has no strong dependency on external standard MIBs, serving as the vendor's foundational private management MIB analogous in role to a mix of SNMPv2-MIB and a proprietary system MIB. It is typically deployed as a baseline health/performance monitoring MIB alongside the other DLINK-3100-* feature MIBs on the same switch family. Engineers can download the DLINK-3100-rndMng file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINK-3100-rndMng. 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 managed switch

Monitoring Examples

An administrator would poll rlCpuUtilDuringLastSecond, rlCpuUtilDuringLastMinute, and rlCpuUtilDuringLast5Minutes to track CPU load trends and detect a sustained spike suggesting a control-plane issue like a broadcast storm or software bug. rlRebootDelay and rndAction let an operator schedule or trigger a controlled switch reboot remotely, while rlGroupMngQuery and rlGroupMngQueryPeriod configure how the switch participates in group management discovery polling.

What Can Be Monitored

CPU utilization (1 sec/1 min/5 min)
CPU utilization monitoring enable state
system reboot delay/action
SNMP version and MIB version supported
group management query interval

OIDs

OID symbolic	OID numeric	Type	Access	Description
rndMng	1.3.6.1.4.1.171.10.94.89.89.1			The private MIB module definition for RND general management MIB.
INT rndSysId	1.3.6.1.4.1.171.10.94.89.89.1.1	INTEGER	read-only	Identification of an RND device. The device type for each integer clarifies the sysObjectID in MIB - II.
INT rndAction	1.3.6.1.4.1.171.10.94.89.89.1.2	INTEGER	read-write	This variable enables the operator to perform one of the specified actions on the tables maintained by the network device. Send actions require support of proprietery File exchange protocol.
OCT rndFileName	1.3.6.1.4.1.171.10.94.89.89.1.3	OCTET STRING	read-write	The name of the file used internally by RND for transferring tables maintained by network devices, using a prorietary File exchange protocol.
OCT rlSnmpVersionSupported	1.3.6.1.4.1.171.10.94.89.89.1.4	OCTET STRING	read-only	Indicates the snmp versions that are supported by this device.
INT rlSnmpMibVersion	1.3.6.1.4.1.171.10.94.89.89.1.5	INTEGER	read-only	Indicates the snmp support version that is supported by this device.
T/F rlCpuUtilEnable	1.3.6.1.4.1.171.10.94.89.89.1.6	TruthValue	read-write	Enables measurement of the device CPU utilization. In order to get real values for rlCpuUtilDuringLastSecond, rlCpuUtilDuringLastMinute and rlCpuUtilDuringLast5Minutes, the value of this object must be true.
INT rlCpuUtilDuringLastSecond	1.3.6.1.4.1.171.10.94.89.89.1.7	INTEGER	read-only	Percentage of the device CPU utilization during last second. The value 101 is a dummy value, indicating that the CPU utilization was not measured (since measurement is disabled or was disabled during last second).
INT rlCpuUtilDuringLastMinute	1.3.6.1.4.1.171.10.94.89.89.1.8	INTEGER	read-only	Percentage of the device CPU utilization during last minute. The value 101 is a dummy value, indicating that the CPU utilization was not measured (since measurement is disabled or was disabled during last minute).
INT rlCpuUtilDuringLast5Minutes	1.3.6.1.4.1.171.10.94.89.89.1.9	INTEGER	read-only	Percentage of the device CPU utilization during the last 5 minutes. The value 101 is a dummy value, indicating that the CPU utilization was not measured (since measurement is disabled or was disabled during last 5 minutes).
TIK rlRebootDelay	1.3.6.1.4.1.171.10.94.89.89.1.10	TimeTicks	read-write	Setting the variable will cause the device to reboot rlRebootDelay timeticks from the moment this variable was set. If not set, the variable will return a value of 4294967295. If set to 4294967295, reboot action is cancelled. The maximum delay is set by the host parameter: reboot_delay_max
rlGroupManagement	1.3.6.1.4.1.171.10.94.89.89.1.11
INT rlGroupMngQuery	1.3.6.1.4.1.171.10.94.89.89.1.11.1	INTEGER	read-write	Setting value query will cause the device to query for UPNP devices on the network. The device will always return value idle for GET.
INT rlGroupMngQueryPeriod	1.3.6.1.4.1.171.10.94.89.89.1.11.2	INTEGER	read-write	Sets desired interval between queries for UPNP devices on the network. Setting 0 will result in no such query. Note that the actual query interval might be less than the set value if another application running in the device requested a shorter interval. Likewise setting 0 will not necessarily stop periodic queries if another application is still interested in periodic polling.
TIK rlGroupMngLastUpdate	1.3.6.1.4.1.171.10.94.89.89.1.11.3	TimeTicks	read-only	The last time rlGroupMng MIB was updated.
rlGroupMngDevicesTable	1.3.6.1.4.1.171.10.94.89.89.1.11.4		not-accessible	The table showing the discovered devices.

IPt rlGroupMngDeviceIdType	1.3.6.1.4.1.171.10.94.89.89.1.11.4.1.1	InetAddressType	not-accessible	The IP address type of the discovered device
IP rlGroupMngDeviceId	1.3.6.1.4.1.171.10.94.89.89.1.11.4.1.2	InetAddress	not-accessible	The IP address of the discovered device
INT rlGroupMngSubdevice	1.3.6.1.4.1.171.10.94.89.89.1.11.4.1.3	INTEGER	not-accessible	A subdevice within the rlGroupMngDeviceId. Only subdevices with greatest specifity will be kept (specific UUID device is more specific than basic device which is in turn more specific than root device.
STR rlGroupMngDeviceDescription	1.3.6.1.4.1.171.10.94.89.89.1.11.4.1.4	DisplayString	read-only	The discovery protocol description of the device.
T/F rlGroupMngGroupMngEnabled	1.3.6.1.4.1.171.10.94.89.89.1.11.4.1.5	TruthValue	read-only	Indicates whether the device has Group Management enable.
STR rlGroupMngGroupLLDPDeviceId	1.3.6.1.4.1.171.10.94.89.89.1.11.4.1.6	DisplayString	read-only	The LLDP device id. If it is empty the device id is not known (either it is a non-MTS device or a non-LLDP supporting MTS device.
