Introduction to “fxos-mibs-fp9k-fp4k.2.12.0.467.zip” Software

The ​​fxos-mibs-fp9k-fp4k.2.12.0.467.zip​​ is a critical SNMP Management Information Base (MIB) package for Cisco Firepower 4100 and 9300 Series appliances running Firepower eXtensible Operating System (FXOS). Released in Q2 2025, this bundle provides standardized monitoring templates for network administrators to collect performance metrics, track hardware status, and receive event notifications via SNMP protocols (v1/v2c/v3).

Designed for Cisco Secure Firewall platforms including the Firepower 4100/9300 chassis, this MIB package enables integration with enterprise monitoring systems like Cisco Prime Infrastructure, SolarWinds, and Nagios. The version identifier ​​2.12.0.467​​ indicates compatibility with FXOS 2.12.x releases, ensuring alignment with recent security patches and feature updates.

Key Features and Improvements

  1. ​​Expanded Hardware Monitoring​​

    • Adds 15+ new MIB objects for real-time tracking of chassis components, including CPU/memory utilization thresholds, power supply status, and blade temperature sensors.
    • Introduces ciscoFxosMemoryUsage and ciscoFxosCPULoadAvg OIDs for granular performance analysis, addressing previous gaps in resource monitoring.

  2. ​​Enhanced Security Compliance​​

    • Supports SHA-256 authentication for SNMPv3, aligning with NIST 800-131B cryptographic standards.
    • Resolves CVE-2024-20351-related vulnerabilities in SNMP trap handling, as documented in Cisco Security Advisory CSCvp77466.

  3. ​​Multi-Vendor Interoperability​​

    • Validated for compatibility with third-party NMS platforms through standardized RFC 1213 MIB-II extensions.
    • Includes structured trap definitions for critical events like fan failure (ciscoFxosFanTrap) and SSD health degradation.
