Description: Provides core management and configuration objects for Dell RND (formerly Radlan) network devices.

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 Dell-rndMng?

Dell-rndMng is the core private management MIB for Dell's RND (formerly Radlan) network device platform, providing general system management, control-action, and performance objects shared across the Dell RND MIB family. It exposes configuration data (system ID, firmware/config file actions, SNMP version support) alongside genuine performance metrics such as CPU utilization. It is explicitly useful for monitoring hardware/software status: rlCpuUtilDuringLastSecond, rlCpuUtilDuringLastMinute, and rlCpuUtilDuringLast5Minutes give real-time and trending CPU load, while rlRebootDelay and rndAction expose reboot/maintenance controls relevant to device uptime and management operations. It underpins other Dell RND-family MIBs (such as Dell-UDP and Dell-TRACEROUTE-MIB) as the common management base and follows standard SNMPv2 SMI conventions. It is typically deployed on Dell PowerConnect/Networking switches as the foundational management module polled alongside more specific feature MIBs. Engineers can download the Dell-rndMng file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-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

  • Dell Networking / PowerConnect switches
  • Dell RND (Radlan)-based network devices

Monitoring Examples

An admin would poll rlCpuUtilDuringLastSecond, rlCpuUtilDuringLastMinute, and rlCpuUtilDuringLast5Minutes to track CPU load trends and detect a sustained spike indicating overload or a runaway process. rndSysId and rndFileName support identifying the device and managing firmware/configuration file operations via rndAction. rlGroupMngQuery and rlGroupMngQueryPeriod configure periodic group-management polling, useful for stack/cluster health checks across multiple RND-based switches.

What Can Be Monitored

  • CPU utilization (1 sec/1 min/5 min)
  • reboot/management actions
  • reboot delay
  • SNMP version support
  • group management polling
  • firmware/config file actions

How to Use in IPNetwork Monitor

Example using rlCpuUtilDuringLastSecond OID:

Select a Dell PowerConnect/Networking switch (core system management/CPU utilization) 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 rlCpuUtilDuringLastSecond into the Find box to locate it in the OID tree, then select it and click OK. It reports the percentage of the device CPU utilization during last second. 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 an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if utilization exceeds 85%, a common warning threshold before sustained high load affects performance. Click Finish to create the monitor; you can adjust any parameter later.
