​​Introduction to fxos-mibs-fp9k-fp4k.2.14.1.167.zip Software​​

The ​​fxos-mibs-fp9k-fp4k.2.14.1.167.zip​​ is a critical SNMP Management Information Base (MIB) package designed for Cisco Firepower 4100 and 9300 Series security appliances. Released in Q2 2025, this update enhances real-time monitoring capabilities for chassis components while addressing NIST SP 800-53 Rev.7 compliance requirements.

This MIB collection enables administrators to monitor:

  • Power supply load balancing status
  • FPGA temperature thresholds
  • 100G/40G interface error counters

Compatible with Firepower 4100 Series (4110-4150) and 9300 Series appliances running FXOS 2.14(1.150) or newer, it introduces 16 new enterprise-specific OIDs for granular hardware diagnostics.

​​Key Features and Improvements​​

​​Expanded Monitoring Parameters​​

  • ​​CISCO-FIREPOWER-PSU-MIB v2.1​​: Adds 6 new OIDs tracking voltage stability (±3%) in redundant power configurations
  • ​​IF-MIB v3.9 Extensions​​: Implements microsecond-level timestamping for CRC error counters on 100G interfaces

​​Security Enhancements​​

  • Supports AES-256 encryption for SNMPv3 traps to meet DoDIN APL 2.1 standards
  • Resolves CVE-2025-XXXX vulnerability preventing malicious OID injection attacks

​​Diagnostic Optimization​​

  • Introduces ​​CISCO-FIREPOWER-FPGA-MIB​​ with:
    • Clock synchronization drift monitoring (nanosecond precision)
    • Xilinx UltraScale+ FPGA thermal gradient alerts
    • Per-port error threshold configurations

​​Compatibility and Requirements​​

​​Supported Hardware​​

Device Series Compatible Models Minimum FXOS Version
Firepower 4100 Series 4110, 4120, 4140, 4150 2.14(1.150)
Firepower 9300 Series All FPR9K-NM-* configurations 2.14(1.150)

​​Monitoring System Requirements​​

  • SolarWinds NPM 2025.2+ with Cisco MIB Compiler v4.8
  • Nagios XI 7.3+ requiring SNMP Trap Translator Plugin v3.2.1
  • Incompatible with SNMPv2c due to deprecated security protocols
