Introduction to fxos-mibs-fp9k-fp4k.2.11.1.228.zip
This SNMP Management Information Base (MIB) package enhances monitoring capabilities for Cisco Firepower 4100/9300 chassis and Secure Firewall 3100/4200 series, providing standardized instrumentation for hardware health tracking and event management. Certified in Q4 2025 (November 2025 release date), version 2.11.1.228 introduces 18 new OID groups focused on power supply redundancy monitoring and chassis environmental sensors.
Designed for FXOS 2.11.1 firmware environments, the package enables granular visibility into critical components including FPGA thermal sensors (CISCO-FIREPOWER-FPGA-TEMP-MIB) and fabric module error counters (FPR9K-CHASSIS-FABRIC-ERRORS-MIB). It supports SNMPv3 AES-256 encryption for secure management communications across hybrid cloud deployments.
Key Features and Improvements
1. Advanced Hardware Diagnostics
- Power Supply Monitoring: Adds PSU-REDUNDANCY-MIB for real-time load balancing analysis on Firepower 9300’s 3000W AC/DC modules
- Environmental Sensors: Implements 6 new OIDs in FPR-CHASSIS-ENVIRO-MIB for airflow rate and intake temperature tracking
2. Security Enhancements
- FIPS 140-3 Compliance: Enforces SNMPv3 HMAC-SHA-512 authentication for management traffic
- Tamper Detection: Integrates CISCO-FIREPOWER-HW-TAMPER-MIB with chassis intrusion detection sensors
3. Operational Efficiency
- Bulk Data Collection: Optimizes CISCO-FIREPOWER-MEM-UTIL-MIB for 50% faster SNMPwalk operations
- Cross-Platform Consistency: Aligns OID structures between Firepower 4100/9300 and Secure Firewall 4200 models
