Introduction to fxos-mibs-fp9k-fp4k.2.14.1.131.zip

This SNMP MIB package provides critical monitoring extensions for Cisco Firepower 4100/9300 series appliances running Firepower eXtensible Operating System (FXOS). Designed for network administrators managing enterprise-grade security platforms, this ZIP archive contains Management Information Base (MIB) files that enable granular SNMP-based monitoring of hardware components, chassis health metrics, and system events.

Compatible with FXOS 2.14.1 and later, this release (version 2.14.1.131) ensures alignment with RFC 1213 MIB-II standards while introducing proprietary extensions for Firepower-specific telemetry. Though Cisco hasn’t publicly disclosed the exact release date, internal version tracking suggests Q1 2025 deployment cycles based on firmware validation timestamps observed in FXOS troubleshooting guides.

Key Features and Improvements

  1. ​​Enhanced Hardware Monitoring​​
    Adds OIDs for tracking power supply units, fan modules, and network interface errors on Firepower 4150/4140/4120/4110 chassis. Supports real-time alerts for critical thresholds like temperature anomalies.

  2. ​​Security Protocol Updates​​
    Implements SHA-256 authentication for SNMPv3 trap transmission, addressing vulnerabilities identified in Cisco Security Advisory cisco-sa-20190220-firpwr-dos.

  3. ​​Troubleshooting Optimization​​
    Introduces new MIB objects for:

    • Monitoring FXOS CLI command execution status
    • Tracking firmware validation tasks
    • Reporting SSD health metrics (wear-leveling, bad block counts)

  4. ​​Cross-Platform Compatibility​​
    Maintains backward compatibility with Firepower 9300’s dual 100G network modules (FPR9K-NM-2X100G) and 40G supervisor modules.

Compatibility and Requirements

Supported Hardware Minimum FXOS Version SNMP Protocol Support
Firepower 4150 2.14(1.131) v1/v2c/v3
Firepower 4140 2.14(1.131) v1/v2c/v3
Firepower 9300 2.14(1.131) v3 (recommended)
Firepower 4120 2.14(1.131) v2c/v3

​​Critical Notes​​:

  • Requires Cisco MIB Compiler 2.2.3+ for proper OID resolution
  • Incompatible with Firepower 1000/2100 series due to chassis architecture differences
  • Must disable SNMPv1 when deploying in FIPS 140-2 compliant environments
