Introduction to fxos-mibs-fp3k.2.12.0.519.zip
This MIB (Management Information Base) package enhances SNMP monitoring capabilities for Cisco Firepower 9300 Series appliances running FXOS 2.12.0 firmware. Released in Q4 2024, version 2.12.0.519 introduces 9 new OIDs for chassis environmental monitoring and improves compatibility with Cisco DNA Center 2.3.5+. Designed for network operations teams managing multi-tenant environments, it provides granular visibility into ASIC buffer utilization and SSD health metrics while maintaining backward compatibility with FXOS 2.10.x deployments.
The package supports Firepower 9300 chassis with Security Module expansion cards, enabling real-time tracking of power supply load balancing and airflow sensor data. Cisco’s validation tools confirm compatibility with SNMPv3 encryption standards as documented in the FXOS Command Reference.
