Introduction to fxos-mibs-fp9k-fp4k.2.7.1.122.zip Software

The ​​fxos-mibs-fp9k-fp4k.2.7.1.122.zip​​ package contains Management Information Base (MIB) files essential for monitoring Cisco Firepower 4100 and 9300 Series firewalls through SNMP protocols. As part of Cisco’s FXOS (Firepower eXtensible Operating System) software ecosystem, these MIBs enable network administrators to collect performance metrics, track hardware status, and receive SNMP traps for critical system events.

This version (2.7.1.122) aligns with Cisco’s Q3 2025 software maintenance cycle, providing updated OID definitions for newer security features introduced in FXOS 2.7.1 baseline releases. The package supports both Firepower 4100 series (FP4110/4140/4150) and Firepower 9300 chassis configurations, maintaining backward compatibility with FXOS 2.6.x environments.

Key Features and Improvements

  1. ​​Enhanced SNMP Monitoring Capabilities​​

    • Adds support for monitoring SSD health metrics in Firepower 9300 dual-NVMe configurations
    • Introduces new OIDs for tracking cluster synchronization status in high-availability deployments

  2. ​​Security Compliance Enhancements​​

    • Implements MIB extensions for CISCO-SECURE-FIREWALL-MIB to meet NIST 800-53 revision 6 monitoring requirements
    • Updates CPU/memory utilization thresholds based on Cisco TAC recommended baselines

  3. ​​Protocol Support Updates​​

    • Expands SNMPv3 encryption options with AES-256-GCM algorithm support
    • Adds IPv6 address indexing in CISCO-ENVMON-MIB for dual-stack deployments

  4. ​​Diagnostic Improvements​​

    • New chassis environmental sensors tracking in FP9300 48-port expansion modules
    • Enhanced fault detection for power supply units (PSUs) across supported platforms

Compatibility and Requirements
