Introduction to fxos-mibs-fp9k-fp4k.2.12.0.498.zip
This essential SNMP Management Information Base (MIB) package provides standardized monitoring capabilities for Cisco Firepower 4100 and 9300 series security appliances running Firepower eXtensible Operating System (FXOS) 2.12.x. Released in Q2 2025, the MIB collection enables network administrators to implement comprehensive device monitoring through SNMP v1/v2c/v3 protocols, with enhanced security compliance for enterprise environments.
The fxos-mibs-fp9k-fp4k.2.12.0.498.zip archive contains 53 updated MIB definitions that align with Cisco’s 2025 Q2 FXOS platform updates. These standardized object identifiers (OIDs) facilitate real-time tracking of chassis health metrics, network module performance statistics, and hardware component statuses through monitoring platforms like SolarWinds or Nagios.
Key Features and Protocol Enhancements
1. Enhanced Monitoring Capabilities
- Introduces 15 new OIDs for SSD health monitoring (CISCO-FIREPOWER-STORAGE-MIB)
- Adds thermal threshold alerts for 9300MX blades (CISCO-ENVMON-MIB)
- Implements power supply load-balancing metrics (CISCO-POWER-ETHERNET-MIB)
2. Security Compliance Updates
- Implements SHA-512 hash validation for MIB package integrity
- Deprecates SNMPv1 community strings in legacy MIBs
