What Is RADLAN-rndMng?
RADLAN-rndMng is a RADLAN (an embedded switch-software company later acquired by Marvell) private MIB providing general research-and-development style management and action objects used across RADLAN-based network devices from many OEM vendors. It exposes system identity, a generic action/command trigger with an associated file name (useful for firmware or config file operations), SNMP version/MIB version reporting, and CPU utilization statistics. As a monitoring tool it directly supports hardware/software health checks: it lets an administrator read current CPU load over the last second, last minute, and last five minutes, and it also exposes controls like reboot delay, tying performance monitoring to operational device management. It is a foundational RADLAN MIB that many other RADLAN-derived MIBs (such as the ACL or interface MIBs) build upon, since RADLAN's embedded switch OS is licensed to numerous white-label switch vendors. It is typically deployed on OEM/white-box managed switches built on the RADLAN embedded switch software stack. Network engineers evaluating or troubleshooting this functionality can download the RADLAN-rndMng file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-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.
What Can Be Monitored
- CPU utilization (last second/minute/5 minutes)
- system/platform identity
- SNMP and MIB version support
- reboot delay setting
- device action/command triggers
Supported Devices
- OEM/white-label switches built on RADLAN embedded switch software
Monitoring Examples
An administrator would poll rlCpuUtilDuringLastSecond, rlCpuUtilDuringLastMinute, and rlCpuUtilDuringLast5Minutes (after confirming rlCpuUtilEnable is set) to track CPU load trends, and a sustained high value across all three intervals would indicate the switch's control-plane CPU is overloaded, possibly from a broadcast storm or a management-plane process runaway. The rndAction and rndFileName objects could be used to trigger a device action such as a firmware operation referencing a specific file, while rndSysId identifies the device platform being managed.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| rndMng | 1.3.6.1.4.1.89.1 | The private MIB module definition for RND general management MIB. | ||
| INT rndSysId | 1.3.6.1.4.1.89.1.1 | INTEGER | read-only | Identification of an RND device. The device type for each integer clarifies the sysObjectID in MIB - II. |
| INT rndAction | 1.3.6.1.4.1.89.1.2 | 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 | 1.3.6.1.4.1.89.1.3 | 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 | 1.3.6.1.4.1.89.1.4 | OCTET STRING | read-only | Indicates the snmp versions that are supported by this device. |
| INT rlSnmpMibVersion | 1.3.6.1.4.1.89.1.5 | INTEGER | read-only | Indicates the snmp support version that is supported by this device. |
| T/F rlCpuUtilEnable | 1.3.6.1.4.1.89.1.6 | 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 | 1.3.6.1.4.1.89.1.7 | 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 | 1.3.6.1.4.1.89.1.8 | 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 | 1.3.6.1.4.1.89.1.9 | 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 | 1.3.6.1.4.1.89.1.10 | 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 |
