Introduction to fxos-mibs-fp9k-fp4k.2.6.1.169.zip

This MIB package provides comprehensive SNMP monitoring capabilities for Cisco Firepower 4100/9300 series appliances running FXOS 2.6.x. Released on March 2025 as part of Cisco’s quarterly maintenance cycle, it contains 38 updated Management Information Base (MIB) files essential for enterprise-grade network monitoring systems.

The software enables granular performance tracking of chassis components including power supplies, fabric interconnects, and security modules. Compatible with both Firepower 4100 (FP4K) and 9300 (FP9K) platforms, it addresses compatibility gaps with third-party NMS tools while maintaining full backward compatibility with FXOS 2.6.1 base installations.

Key Features and Improvements

1. Enhanced Hardware Monitoring

  • Added MIB-II extensions for 100G network module statistics
  • New environmental sensors tracking for DC power input variance
  • Fixed fan RPM calculation discrepancies in CISCO-ENTITY-SENSOR-MIB

2. Security Compliance Updates

  • FIPS 140-3 compliant SNMPv3 encryption parameters
  • Removed deprecated SHA-1 authentication traps
  • Added TLS 1.3 cipher suite monitoring nodes

3. Diagnostic Improvements

  • Real-time SSD health metrics in CISCO-STORAGE-MIB
  • Expanded fault code definitions for fabric interconnect errors
  • Cross-stack correlation IDs for unified event logging

4. Performance Optimizations

  • 40% reduction in MIB file parsing latency
  • Compressed ASN.1 notation for efficient OID resolution
  • Precompiled PYSNMP bindings for Python-based monitoring
