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

This MIB collection package provides essential Simple Network Management Protocol (SNMP) monitoring templates for Cisco Firepower 4100/9300 series appliances running Firepower eXtensible Operating System (FXOS) 2.7.1.122. Released in Q2 2025 as part of Cisco’s quarterly maintenance cycle, these Management Information Base (MIB) files enable granular performance monitoring of chassis components including power supplies, fan modules, and ASIC utilization.

The package supports automated health status reporting through SNMPv3 with SHA-256 authentication, particularly crucial for environments requiring FedRAMP Moderate compliance. Compatible with both Firepower 9000 and 4000 series hardware, this MIB collection ensures interoperability with enterprise monitoring systems like SolarWinds and Nagios Core.
