Introduction to fxos-mibs-fp9k-fp4k.2.7.1.92.zip
The fxos-mibs-fp9k-fp4k.2.7.1.92.zip is Cisco’s Management Information Base (MIB) package for Firepower 4100/9300 Series appliances running FXOS 2.7.1. This essential monitoring component enables SNMP-based network management integration, providing structured telemetry data for chassis health, security module performance, and interface metrics. Designed to complement FXOS 2.7.1 firmware releases, the package contains updated object identifiers (OIDs) for comprehensive visibility into hardware components including power supplies, fan arrays, and security module throughput.
Cisco officially released this MIB collection in Q1 2025 to address monitoring gaps in multi-instance Firepower Threat Defense deployments. It supports both appliance mode (default) and legacy platform configurations, ensuring backward compatibility with Cisco Prime Infrastructure and third-party SNMP managers like SolarWinds and Zabbix.
