Description: OS-level network bonding modes, carrier detection, MAC failover policy, and vNIC operational state for Cisco UCS host agents

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 CISCO-UNIFIED-COMPUTING-OS-MIB?

This Cisco UCS Managed Information Model package MIB covers host-OS-level networking settings applied through UCS service profiles, including NIC bonding modes, ARP-based link monitoring policies, carrier detection, and MAC failover behavior for virtual NICs. It exposes configuration objects for link-monitoring policies and target addresses, plus vNIC operational state. Monitoring-wise it is used to check the software/network-status health of a server's OS-level network stack, for instance verifying an ARP link monitoring policy's frequency and target list are correctly applied, or confirming vNIC operational state to catch a failed-over or down bonded interface. It depends on the umbrella CISCO-UNIFIED-COMPUTING-MIB and relates to the broader UCS network/vNIC MIBs for full picture of server connectivity. It is used within Cisco UCS blade/rack servers where OS-level bonding and failover policies are configured via service profiles. Network engineers evaluating or troubleshooting this functionality can download the CISCO-UNIFIED-COMPUTING-OS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-UNIFIED-COMPUTING-OS-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

  • Cisco UCS blade servers
  • Cisco UCS rack servers

Monitoring Examples

An administrator would check cucsOsARPLinkMonitoringPolicyTable / cucsOsARPLinkMonitoringPolicyEntry, examining cucsOsARPLinkMonitoringPolicyFrequency and cucsOsARPLinkMonitoringPolicyUseAllARPTargets to confirm link monitoring is correctly configured for a bonded interface. The related cucsOsARPTargetTable lists the specific ARP target IP addresses used to detect link failures; a failed ARP monitoring policy match could explain an unexpected NIC failover event. This helps correlate OS-level network health with the underlying UCS fabric connectivity.

What Can Be Monitored

  • ARP link monitoring policy frequency and targets
  • NIC bonding/failover configuration
  • vNIC operational state
  • carrier detection status
