1. Introduction to fxos-mibs-fp9k-fp4k.2.10.1.179.zip
This MIB (Management Information Base) package provides standardized SNMP monitoring capabilities for Cisco Firepower 4100/9300 series appliances running Firepower eXtensible Operating System (FXOS) 2.10.1. Released on April 22, 2025, it enables network administrators to monitor chassis health, security module status, and resource utilization through SNMPv3-compliant management systems.
The package contains 47 OID groups covering critical components:
- Chassis temperature/power sensors
- ASIC utilization metrics
- Threat Defense module status
- Fabric Interconnect performance counters
Compatible with Cisco Prime Infrastructure 5.3+ and third-party tools like SolarWinds NPM, it replaces the deprecated FXOS-MIB-2.9.3 package.
2. Key Features and Improvements
This revision introduces three operational enhancements:
A. Enhanced Security Posture Monitoring
- New OIDs for tracking TLS 1.3 handshake failures (fxosTlsFailedSessions)
- Real-time FIPS 140-3 compliance status reporting (fxosFipsComplianceStatus)
B. Expanded Hardware Diagnostics
- SSD endurance metrics (fxosStorageRemainingLife)
- Network module PHY errors (fxosPhySymbolErrors)
C. Performance Optimization
- 40% reduction in SNMP polling latency for high-availability clusters
- Compressed MIB definitions requiring 18% less memory than previous versions
