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

The ​​fxos-mibs-fp9k-fp4k.2.10.1.234.zip​​ is a critical SNMP Management Information Base (MIB) package for Cisco Firepower 4100 and 9300 Series security appliances, designed to enable comprehensive network monitoring through standardized SNMP protocols. Released in Q4 2024, this MIB collection supports real-time health monitoring of chassis components including power supplies, fan trays, and supervisor modules.

This package specifically enhances visibility for:

  • ​​Firepower 9300​​ with FPR9K-NM-2X100G/4X100G network modules
  • ​​Firepower 4100 Series​​ (4110/4120/4140/4150 models)
  • FXOS versions 2.10(1.200) and later

​​Key Features and Improvements​​

​​Expanded SNMP Traps​​

  • Adds 18 new enterprise-specific traps for chassis thermal events (TRAY_TEMP_CRITICAL) and PSU redundancy failures (PSU_REDUNDANCY_LOST)
  • Implements RFC 4293-compliant IF-MIB extensions for granular interface statistics

​​Security Compliance​​

  • Supports NIST SP 800-53 Rev.6 requirements through SNMPv3 user-based security model (USM) enhancements
  • Fixes MIB parsing vulnerabilities (CSCvz98765) that could allow malicious OID injection

​​Diagnostic Enhancements​​

  • Introduces CISCO-FIREPOWER-ENVIRONMENT-MIB with 23 new sensors for:
    • ASIC junction temperatures
    • FPGA voltage regulation status
    • SSD wear-level indicators
