Introduction to “fxos-mibs-fp9k-fp4k.2.7.1.122.zip” Software

This MIBs (Management Information Base) package is an essential monitoring component for Cisco Firepower 4100 and 9300 series security appliances running Firepower eXtensible Operating System (FXOS). Designed for network administrators, the file provides standardized SNMP data structures to facilitate device health monitoring through network management systems like Cisco Prime Infrastructure or third-party SNMP tools.

The version 2.7.1.122 release aligns with FXOS 2.7.1 platform requirements, offering updated OID definitions for chassis components including supervisor modules, network interfaces, and environmental sensors. Cisco officially recommends this package for all Firepower 4100/9300 deployments requiring SNMP-based infrastructure monitoring.
