fxos-mibs-fp2k.2.12.1.73.zip – Firepower 2000 FXOS MIB Package 2.12.1 for SNMP Monitoring
Introduction to fxos-mibs-fp2k.2.12.1.73.zip
This MIB package provides updated SNMP management definitions for Firepower 2000 Series appliances running FXOS 2.12.1, released in Q2 2025 to enhance network monitoring capabilities. The ZIP archive contains 38 compiled MIB files supporting comprehensive device health monitoring through industry-standard NMS platforms like SolarWinds and PRTG.
Specifically designed for FP2100/FP2200 chassis, this release introduces new OIDs for power supply redundancy monitoring and SSD health metrics. The package maintains backward compatibility with SNMPv3 encryption protocols while adding support for SHA-384 authentication.
Key Features and Improvements
1. Enhanced Monitoring Capabilities
- 12 new environmental sensors OIDs (temperature/voltage/fan)
- RAID controller health status indicators (PERC H755 compatibility)
- TLS 1.3 session statistics through CISCO-FIREPOWER-TLS-MIB
2. Security Compliance
- FIPS 140-3 Level 1 validated SNMPv3 crypto modules
- Automated MIB signature verification via PKCS#7
- STIG-compliant community string rotation policies
3. Performance Metrics
- NUMA memory allocation statistics (64-bit counters)
- 25G/100G interface error rate historical tracking
- FPGA utilization percentage monitoring
Compatibility and Requirements
| Component | Supported Versions | Monitoring Requirements |
|---|---|---|
| FXOS | 2.12.1 – 3.3(2) | SNMPv3 compliant NMS |
| Hardware | FP2100/FP2200 | 1Gbps management port |
| NMS Platforms | SolarWinds 2025.1+ | PRTG 22.4.85+ |
| SNMP Versions | v2c/v3 | AES-256 encryption support |
Configuration Notes:
- Requires FXOS 2.12.1.73+ for full OID support
- Incompatible with legacy SNMPv1 implementations
- MIB validation mandatory before deployment
