Introduction to fxos-mibs-fp9k-fp4k.2.10.1.271.zip
The fxos-mibs-fp9k-fp4k.2.10.1.271.zip is Cisco’s standardized Management Information Base (MIB) package for Firepower 4100/9300 series appliances running Firepower eXtensible Operating System (FXOS). This software bundle provides SNMP monitoring capabilities for chassis health, hardware components, and system performance metrics, aligning with Cisco’s commitment to unified network management frameworks.
Released in Q1 2025, version 2.10.1.271 introduces updated MIB definitions to support newer FXOS features while maintaining backward compatibility with Cisco Secure Network Analytics and third-party monitoring tools like SolarWinds and PRTG. The package specifically targets:
- Firepower 4100 Series: 4110, 4120, 4140, 4150
- Firepower 9300 Series: All modular configurations
- FXOS Versions: 2.10.x and later
Key Features and Improvements
-
Enhanced SNMPv3 Security Profiles
Adds SHA-256 authentication and AES-256 encryption support for secure monitoring sessions, addressing CVE-2024-20351-related vulnerabilities in previous MIB implementations. -
Hardware Health Monitoring
- New OIDs for power supply load balancing (PSU-3K-MIB)
- Temperature thresholds for 100G network modules (FPR9K-NM-2X100G)
- SSD wear-leveling metrics (STORAGE-MIB)
-
Protocol Support Expansion
- LLDP-MIB extensions for VXLAN EVPN topologies
- ENTITY-MIB mappings for multi-instance ASA/FTD deployments
-
Performance Optimization
Reduces SNMP polling overhead by 40% through compressed MIB tree structures and optimized OID indexing.
