Description: A private MIB module for general management of Cisco Small Business switches, including CPU utilization metrics and system configuration.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CISCOSB-rndMng with a free 30-day trial of IPNetwork Monitor.

What Is CISCOSB-rndMng?

CISCOSB-rndMng is a broad, general-purpose Cisco Small Business private MIB for overall switch management, bundling system identification, file/firmware actions, SNMP version support, CPU utilization statistics, reboot control, and group-management/discovery settings. It spans configuration (system ID, file actions, reboot delay) and performance-monitoring categories (CPU load over multiple time windows). It is explicitly useful for monitoring software/hardware status: rlCpuUtilDuringLastSecond/LastMinute/Last5Minutes give a direct view of CPU load trends that reveal an overloaded control plane, while rndAction and rlRebootDelay relate to device reboot/software-management operations. It is a foundational CISCOSB private-tree MIB that many other CISCOSB MIBs are versioned and grouped alongside, without a strong dependency on external standard MIBs beyond general SNMPv2 conventions. It is used across the CISCOSB switch/router product line as the primary general system-health and management MIB. Network engineers evaluating or troubleshooting this functionality can download the CISCOSB-rndMng file directly to load it into their MIB browser.

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

  • Cisco Small Business switches and routers

Monitoring Examples

An administrator would poll rlCpuUtilDuringLastSecond, rlCpuUtilDuringLastMinute, and rlCpuUtilDuringLast5Minutes to build a CPU-load trend and detect a sustained spike suggesting a runaway process or attack traffic. Checking rndSysId and rlSnmpMibVersion confirms device identity and MIB compatibility during inventory audits, while rndAction and rndFileName are used to trigger and track firmware or configuration file operations. A CPU utilization value pinned near 100% across all three time windows, combined with rlRebootDelay being set, often indicates an administrator-initiated recovery reboot is pending due to a performance problem.

What Can Be Monitored

  • CPU utilization (1 sec/1 min/5 min)
  • system identifier
  • reboot delay/status
  • firmware/config file action
  • SNMP/MIB version support
  • group management discovery settings
