Introduction to fxos-mibs-fp9k-fp4k.2.10.1.234.zip

The ​​fxos-mibs-fp9k-fp4k.2.10.1.234.zip​​ is a critical Management Information Base (MIB) package designed for Cisco Firepower 4100 and 9300 series security appliances running Firepower eXtensible Operating System (FXOS). This software bundle provides standardized SNMP monitoring and management capabilities, enabling network administrators to integrate these devices with enterprise Network Management Systems (NMS) for real-time health checks, fault detection, and performance analytics.

Released in Q1 2025, version 2.10.1.234 aligns with Cisco’s ongoing updates to enhance SNMP protocol support and data model coverage. It ensures full compatibility with FXOS 2.10.x deployments and addresses interoperability requirements for mixed-environment monitoring.

Key Features and Technical Improvements

This MIB package introduces several operational enhancements:

  1. ​​Extended Fault Event Tracking​​:

    • Supports new SNMP traps (cfprApFaultActiveNotif and cfprApFaultClearNotif) for granular hardware/software failure alerts, including chassis temperature thresholds and power supply anomalies.
    • Adds varbind extensions to IF-MIB linkUp/linkDown notifications for precise interface status diagnostics.

  2. ​​Enhanced Inventory Management​​:

    • Expands CISCO-FIREPOWER-AP-MIB to include FPGA firmware versions, network module serial numbers, and ROMMON details for Firepower 9300’s 100G modules.
    • Introduces read-only OID mappings for XML API data fields, ensuring parity between CLI/UI and SNMP-based monitoring.

  3. ​​Performance Optimization​​:

    • Reduces SNMP polling latency by 18% through optimized MIB tree indexing.
    • Adds cfprApEtherPauseStatsTable in CISCO-FIREPOWER-AP-ETHER-MIB for deep packet analysis on 100G interfaces.

Compatibility and System Requirements

This version is validated for the following configurations:

​​Component​​ ​​Supported Models/Software​​
Hardware Platforms Firepower 4100, 9300, 4150, 4140, 4120
FXOS Versions 2.10.1.x, 2.10.2.x
Network Modules FPR9K-NM-2X100G, FPR9K-NM-4X100G
NMS Compatibility SolarWinds, Nagios XI, Cisco Prime

​​Critical Notes​​:

  • Requires Cisco FXOS 2.10.1.58 or later for full MIB functionality.
  • Incompatible with third-party SNMP managers using non-standard OID traversal methods.
