Description: Manages system-level operational parameters including reboot scheduling and management policies.

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 RADLAN-SYSMNG-MIB?

RADLAN-SYSMNG-MIB is a Marvell/RADLAN private enterprise MIB reporting on internal system-resource pools managed by the switch's System Manager component, such as hardware and software routing-table resources. It exposes a resource table, keyed by route type, reporting current and maximum usage for both software and hardware pools (routes, next-hops), including temporary maximum overrides and per-unit usage in a stack. This is a capacity/resource-health monitoring MIB: it detects when a switch approaches or exceeds a hardware resource limit (such as TCAM/FIB size for routes or next-hops), a common cause of silent packet drops or route-installation failures, distinct from CPU/memory of the control plane itself. It has no apparent dependency on other standard MIBs, being a self-contained RADLAN system-resource extension tied to the underlying switch silicon. It is typically deployed on RADLAN-based Layer 3 switches where admins monitor hardware forwarding-table (FIB/TCAM) exhaustion. Engineers can download the RADLAN-SYSMNG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-SYSMNG-MIB. 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.

OEM routing switches licensing the RADLAN software stack
Marvell (RADLAN) OEM switch platform — embedded in many rebranded switches (D-Link, Dell, etc.)

Monitoring Examples

An administrator investigating intermittent routing failures would poll rlSysmngResourceTable/rlSysmngResourceEntry for a given rlSysmngResourceRouteType, comparing rlSysmngResourceCurrentUseHw against rlSysmngResourceCurrentMaxHw to see if the hardware route table is nearly full. rlSysmngResourceCurrentNexthopUse versus rlSysmngResourceCurrentNexthopMaxHw reveals next-hop table exhaustion, a frequent cause of ECMP or tunnel routes silently failing to install. rlSysmngResourceTemporaryMaxHw shows whether a temporary resource-limit override is in effect, explaining a ceiling that differs from the documented hardware maximum.

What Can Be Monitored

hardware route table usage vs maximum
software route table usage vs maximum
next-hop table usage vs maximum
temporary resource limit overrides
per-stack-unit resource usage
