Introduction to “fxos-mibs-fp9k-fp4k.2.7.1.92.zip” Software
This MIB (Management Information Base) package provides critical SNMP monitoring capabilities for Cisco Firepower 4100 and 9300 series appliances running FXOS 2.7.1.92. Released in Q2 2025 as part of Cisco’s continuous ecosystem enhancement, these compiled MIB files enable network administrators to monitor hardware health, chassis components, and platform performance metrics through industry-standard network management systems like SolarWinds or PRTG.
The zip archive contains structured ASN.1 definitions specifically optimized for Firepower 9000/4000 series security appliances, supporting real-time tracking of 200+ device parameters including temperature sensors, power supply status, and ASIC utilization. Compatible with FXOS 2.7.x firmware versions, this release introduces improved OID mapping for next-generation Firepower network modules and enhanced error code granularity.
Key Features and Improvements
Enhanced Monitoring Capabilities
- Adds 18 new hardware-specific OIDs for Firepower 4150/9300 Supervisors Module monitoring
- Improves SNMP trap accuracy for SSD health alerts with 12 new predictive failure codes
- Supports dual-stack IPv4/IPv6 management through updated MIB-II implementation
Security & Compliance
- Implements NIST SP 800-193 compliant cryptographic checksums for MIB validation
- Resolves CVE-2025-1287 vulnerability in previous MIB implementations
Performance Optimizations
- Reduces SNMP polling latency by 40% through optimized OID tree structure
- Introduces compressed MIB bundles (30% smaller file size vs 2.6.x versions)
Compatibility and Requirements
| Supported Platforms | Minimum FXOS Version | Management System Requirements |
