Introduction to fxos-mibs-fp9k-fp4k.2.6.1.174.zip Software
The fxos-mibs-fp9k-fp4k.2.6.1.174.zip is Cisco’s official Management Information Base (MIB) package for Firepower 4100/9300 series appliances running FXOS 2.6(1). Released on April 25, 2025, this collection of SNMP MIB files enables granular monitoring of chassis components through network management systems like Cisco Prime Infrastructure or third-party SNMP tools.
Designed to complement FXOS 2.6.1.174 firmware bundles, these MIBs provide standardized access to hardware telemetry including power supply status, fan RPM metrics, and ASIC temperature readings. The package supports both Firepower 4100 (FP4K) and 9300 (FP9K) platforms, addressing monitoring gaps identified in earlier FXOS 2.5.x releases.
Key Features and Improvements
1. Enhanced Hardware Visibility
- Added CISCO-FIREPOWER-CHASSIS-MIB for real-time blade health monitoring
- New environmental sensors for 100G QSFP28 transceiver diagnostics
2. Security Compliance Updates
- SNMPv3 user-based security model (USM) compatibility enhancements
- Removed deprecated MIB objects affecting NIST 800-53 compliance
3. Performance Optimization
- Reduced SNMP polling latency by 22% through MIB structure optimization
- Added bulk counter support for high-density 40G/100G interface statistics
4. Diagnostic Enhancements
- New trap definitions for SSD wear-leveling alerts (CISCO-STORAGE-MIB)
- Expanded error code coverage in CISCO-FIREPOWER-FABRIC-MIB
5. Third-Party Integration
- Precompiled MIB modules for SolarWinds, PRTG, and Zabbix
- Resolved parsing conflicts with NET-SNMP 5.9.3+ implementations
