Description: Manages system-level hardware components including fans, power supplies, and temperature for Dell Networking.

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-NETWORKING-SYSTEM-COMPONENT-MIB?

DELL-NETWORKING-SYSTEM-COMPONENT-MIB is a Dell Networking OS private MIB covering system-level hardware component information on Dell Networking switches, with a particular focus on CAM (Content Addressable Memory) table usage on linecards, alongside broader system component health such as fans, power supplies, and temperature per its short description. It exposes CAM usage tables (camUsageTable/camUsageL2Table) keyed by slot and pipe number, reporting per-partition total versus used CAM entries (camUsageTotal/camUsageUsed) for L2, L3 ingress/egress, and L3-external tables on Broadcom-based S-series platforms. Its monitoring value spans both hardware capacity and platform status: administrators track CAM utilization to catch forwarding-table exhaustion before it causes packet drops or route/ACL programming failures, alongside the broader system-component objects for fan, power-supply, and temperature status that flag physical hardware faults. It is a Dell Networking OS-specific MIB, tied to underlying Broadcom silicon table structures on S-series switches, and complements the standard ENTITY-MIB for physical inventory. It is deployed in Dell Networking S-series data-center switch environments, and a DELL-NETWORKING-SYSTEM-COMPONENT-MIB download is a standard part of setting up CAM capacity planning and hardware status monitoring in those environments.

IPNetwork Monitor allows you to monitor SNMP objects defined in DELL-NETWORKING-SYSTEM-COMPONENT-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.

Monitoring Examples

A network engineer would poll camUsageTable (camUsageSlot/camUsagePipeNum/camUsagePartId) and compare camUsageUsed to camUsageTotal to detect a linecard approaching CAM exhaustion in a specific table partition, which would predict imminent route or ACL programming failures. camUsageL2Table's L2-specific entries (camUsageL2Slot/camUsageL2PipeId) let the engineer narrow down whether the pressure is coming from MAC-table (L2) versus L3 forwarding entries. dellNetSysComponentTrap would fire to alert on associated hardware component faults such as a failed fan or power supply.

What Can Be Monitored

CAM table usage vs total capacity
per-partition (L2/L3 ingress-egress) CAM usage
fan status
power supply status
temperature
