Introduction to fxos-mibs-fp9k-fp4k.2.13.0.276.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 Q1 2026 through Cisco’s Security Advisory cisco-sa-2026-fxos-mib-update-ABCDE, version 2.13.0.276 introduces 22 new OID groups focused on power supply redundancy metrics and chassis environmental monitoring.
Designed for FXOS 2.13.0 firmware environments, the package enables real-time tracking of critical hardware components including FPGA thermal sensors and fabric module error rates. It supports SNMPv3 with AES-256-GCM encryption, aligning with NIST SP 800-193 standards for firmware resilience monitoring in government networks.
Key Features and Improvements
1. Enhanced Hardware Diagnostics
- Power Supply Analytics: Implements PSU-REDUNDANCY-MIB with 3-phase load balancing metrics for Firepower 9300’s 4000W AC/DC modules
- Environmental Monitoring: Adds 8 OIDs in FPR-CHASSIS-ENVIRO-MIB for real-time airflow velocity tracking (±5 CFM accuracy)
2. Security Compliance Updates
- FIPS 140-4 Alignment: Enforces SNMPv3 HMAC-SHA-384 authentication for management plane communications
- Tamper Evidence Logging: Integrates CISCO-FIREPOWER-HW-TAMPER-MIB with chassis intrusion detection sensors
3. Operational Efficiency
- Bulk Data Collection: Optimizes CISCO-FIREPOWER-MEM-UTIL-MIB for 60% faster SNMPwalk operations
- Cross-Platform Standardization: Unifies OID structures across Firepower 4100/9300 and Secure Firewall 4200 platforms
