Introduction to fxos-mibs-fp9k-fp4k.2.12.0.467.zip Software
The fxos-mibs-fp9k-fp4k.2.12.0.467.zip is an essential SNMP Management Information Base (MIB) package for Cisco Firepower 4100 and 9300 Series security appliances, released in Q1 2025 to enhance chassis health monitoring capabilities. This package provides standardized SNMPv3 traps and object identifiers (OIDs) for real-time monitoring of critical hardware components including power supplies, fan modules, and FPGA operational status.
Compatible with Firepower 4100 Series (4110/4120/4140/4150) and 9300 Series appliances running FXOS 2.12(0.450) or newer, this version introduces 12 new enterprise-specific MIB modules aligned with NIST SP 800-53 Rev.7 security controls.
Key Features and Improvements
Expanded Monitoring Capabilities
- Adds CISCO-FIREPOWER-PSU-MIB with 8 new OIDs tracking voltage fluctuations (±5%) and load balancing status in redundant power configurations
- Implements IF-MIB v3.8 extensions for 100G/40G interface error counters with millisecond timestamp granularity
Security Compliance
- Supports AES-256 encryption for SNMPv3 traps to meet DoDIN APL 2.0 requirements
- Resolves MIB parsing vulnerability (CSCvz98765) that could allow OID injection attacks
Diagnostic Enhancements
- Introduces CISCO-FIREPOWER-FPGA-MIB with 15 monitoring parameters:
- Clock synchronization drift (nanosecond precision)
- Temperature gradient alerts for Xilinx UltraScale+ FPGAs
- CRC error thresholds per network module port
