Description: MIB defining SNMP trap notifications for KVM switch events including user sessions, power, and connectivity status changes.

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 KVMS3-TRAP-MIB?

KVMS3-TRAP-MIB is a vendor MIB (branded under the 'fsc' Fujitsu Siemens Computers prefix, built on an Avocent OID subtree) defining SNMP trap notifications for a KVM-over-IP switch, the KVM S3 series. It exposes trap payload objects covering user session activity, firmware image upgrade progress, and cascade-switch/server topology changes rather than a large table of polled counters. It is explicitly useful for monitoring software status such as firmware upgrade version and result, and connectivity/topology status such as which cascade switch or target server a session is attached to. It has a notable dependency on the Avocent enterprise OID structure (avocent, ds, dsManagement), reflecting that the KVM S3 hardware is Avocent-based technology rebranded by Fujitsu Siemens. It is deployed in data center environments where KVM-over-IP switches provide remote console access to racks of servers. Engineers can download the KVMS3-TRAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in KVMS3-TRAP-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

  • Fujitsu Siemens/Avocent KVM-over-IP switch (KVM S3 series)

Monitoring Examples

fscKvmS3TrapObjectImageCurrentVersion, fscKvmS3TrapObjectImageNewVersion, and fscKvmS3TrapObjectImageUpgradeResults are carried together in a firmware-upgrade trap so an admin is notified when a KVM switch completes or fails an upgrade. fscKvmS3TrapObjectSessionIdentifier and fscKvmS3TrapObjectUserName identify who opened or closed a KVM session, while fscKvmS3TrapObjectCascadeSwitchName/fscKvmS3TrapObjectOldCascadeSwitchName flag when a cascaded switch is added, removed, or renamed within the KVM chain.

What Can Be Monitored

  • user session start/end
  • firmware upgrade status and version
  • cascade switch topology changes
  • server connection/rename events
  • target server identity
