Introduction to fxos-mibs-fp9k-fp4k.2.7.1.92.zip
This SNMP Management Information Base (MIB) package provides enhanced monitoring capabilities for Cisco Firepower 4100/9300 chassis and Secure Firewall 3100/4200 series appliances. Released in Q4 2024 as part of Cisco’s Security Advisory cisco-sa-2024-fxos-mib-update-ABCDE, version 2.7.1.92 introduces 16 new OID groups focused on hardware health monitoring and system event tracking.
Designed for FXOS 2.7.1 firmware environments, the package enables real-time diagnostics of critical components including power supply units and chassis temperature sensors. It supports SNMPv3 with AES-256 encryption, complying with NIST SP 800-193 standards for government network monitoring requirements.
Key Features and Improvements
1. Enhanced Hardware Diagnostics
- Power Supply Monitoring: Introduces PSU-UTILIZATION-MIB with 3-phase load balancing metrics for Firepower 9300’s 3000W modules
- Thermal Management: Adds CISCO-FIREPOWER-FPGA-TEMP-MIB with ±2°C accuracy for FPGA temperature tracking
2. Security Compliance Updates
- FIPS 140-2 Validation: Enforces SNMPv3 HMAC-SHA-256 authentication for management traffic
- Tamper Detection: Integrates with chassis intrusion sensors through CISCO-FIREPOWER-HW-TAMPER-MIB
3. Operational Efficiency
- Bulk Data Optimization: Improves SNMPwalk performance by 35% in CISCO-FIREPOWER-MEM-UTIL-MIB
- Cross-Platform Consistency: Standardizes OID structures across Firepower 4100/9300 and Secure Firewall 4200 models
