Description: Core system management MIB for 3Com SuperStack switching systems, covering chassis, module inventory, software versions, and system configuration.

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 A3COM-SWITCHING-SYSTEMS-MIB?

A3COM-SWITCHING-SYSTEMS-MIB is the core system-management MIB for 3Com SuperStack switching systems, exposing chassis identity, module inventory, hardware/software revision, and system configuration data. It covers general system categories such as system name and manufacturer, memory sizes (RAM, flash, NVRAM), hardware revision, software revision, and build time, plus SNMP agent mode configuration. This MIB is directly used to monitor hardware and software status: memory size fields help gauge available flash/RAM capacity for firmware images, and software/hardware revision objects let an administrator confirm a device is running the expected firmware version or identify outdated hardware needing replacement. It functions as the root MIB for the broader 3Com switching-systems MIB family (file-transfer and route-policy modules register beneath it), so it has an internal dependency relationship with those sibling MIBs. It is typically deployed for inventory and firmware-version auditing across fleets of 3Com SuperStack switches. Engineers can download the A3COM-SWITCHING-SYSTEMS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-SWITCHING-SYSTEMS-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.

Supported Devices

  • 3Com SuperStack switch

Monitoring Examples

An administrator would poll a3ComSysSystemSoftwareRevision and a3ComSysSystemHardwareRevision to audit which firmware and hardware revision a given switch is running, flagging units that need a firmware upgrade. Checking a3ComSysSystemMemorySize, a3ComSysSystemFlashMemorySize, and a3ComSysSystemNvMemorySize together reveals whether a switch has enough free flash to accept a new image before an upgrade is attempted, and a3ComSysSystemBuildTime helps correlate the installed image with a known release.

What Can Be Monitored

  • software revision/version
  • hardware revision
  • flash memory size
  • RAM memory size
  • system name/identity
