Introduction to “fxos-mibs.2.8.1.105.zip” Software
This MIB (Management Information Base) package provides comprehensive SNMP monitoring capabilities for Cisco FXOS-based security platforms, including Firepower 4100/9300 chassis and ASA 5500-X Series Firewalls. Released in Q1 2025 as part of Cisco’s quarterly maintenance cycle, version 2.8.1.105 introduces 14 new OID groups for enhanced hardware diagnostics and performance tracking. The ZIP archive contains 38 standardized and enterprise-specific MIB files compliant with SNMPv3 security frameworks.
Designed for network monitoring systems like SolarWinds and PRTG, this collection enables granular visibility into chassis components including power supplies, fan modules, and SSP (Security Services Processor) utilization. Compatible with FXOS 2.3(1.58) through 2.8(1.105), it serves as essential infrastructure for enterprises implementing ISO 27001-compliant network surveillance.
