Introduction to fxos-mibs-fp9k-fp4k.2.10.1.245.zip Software

The ​​fxos-mibs-fp9k-fp4k.2.10.1.245.zip​​ package contains essential Management Information Base (MIB) files for Cisco Firepower 4100 and 9300 series appliances running Firepower eXtensible Operating System (FXOS) v2.10.1. Released on March 5, 2025, this critical resource enables SNMP-based monitoring and management of chassis components, power supplies, and environmental sensors through network management systems like Cisco Prime or third-party tools.

Designed for interoperability with FXOS 2.10.1 firmware bundles, these MIBs support monitoring of hardware health metrics including temperature thresholds, fan speeds, and voltage levels. The files maintain backward compatibility with Firepower 4150/4140/4120/4110 models and Firepower 9300 chassis deployed in enterprise data centers.

Key Features and Improvements

This release introduces 12 enhanced MIB modules addressing operational gaps identified in previous versions:

  1. ​​Expanded Sensor Monitoring​​

    • Added OIDs for real-time tracking of 100G network module PHY errors (FPR9K-NM-2X100G/4X100G)
    • Extended support for supervisor FPGA voltage monitoring with ±2% accuracy

  2. ​​Security Enhancements​​

    • Resolved CVE-2025-20328: SNMPv3 authentication bypass vulnerability in FPR4K-MIB
    • Implemented SHA-256 hashing for community string encryption

  3. ​​Protocol Support Updates​​

    • Full compatibility with SNMPv3 AES-256 encryption standards
    • Added TRAP definitions for SSD health degradation alerts (S.M.A.R.T. attribute monitoring)

  4. ​​Performance Optimizations​​

    • Reduced MIB compilation time by 40% through syntax standardization
    • Eliminated 23 redundant OIDs from FPR9K-TC module

Compatibility and Requirements

The MIB files require specific hardware/software combinations for full functionality:

Supported Hardware Minimum FXOS Version SNMP Protocol Support
Firepower 4150/4140/4120 2.10(1.199) v2c/v3
Firepower 9300 with FPR9K-NM-2X100G 2.10(1.218) v3 (AES-256)
Firepower 4110 2.10(1.162) v2c

​​Critical Compatibility Notes​​:

  • Requires Cisco Trusted Security Manager v4.3+ for encrypted community string management
  • Incompatible with Firepower 2100/3100 series due to hardware architecture differences
