​​Introduction to fxos-mibs-fp9k-fp4k.2.14.1.163.zip​​

This MIB (Management Information Base) package provides SNMP monitoring capabilities for Cisco Firepower 4100/9300 appliances running FXOS (Firepower Extensible Operating System). Released as part of Cisco’s ongoing network management optimization efforts, version 2.14(1.163) enhances SNMPv3 support and aligns with Cisco’s security-first approach for enterprise-grade threat defense platforms.

The package specifically supports:

  • ​​Firepower 4100 Series​​: 4110/4120/4140/4150
  • ​​Firepower 9300 Series​​: 9300/9300-20/9300-40/9300-80
  • ​​FXOS Versions​​: Compatible with FXOS 2.14(x) and later

Cisco officially published this update in Q2 2025 to address SNMP monitoring gaps identified in previous MIB packages. It enables granular tracking of chassis health metrics, including power supply status, fan performance, and thermal sensors – critical for maintaining 24/7 data center operations.

​​Key Features and Improvements​​

​​Enhanced SNMPv3 Security​​

Implements AES-256 encryption for SNMPv3 traps, aligning with NIST SP 800-90B standards. This prevents unauthorized access to device telemetry in multi-tenant environments.

​​Real-Time Hardware Monitoring​​

New OIDs (Object Identifiers) added for:

  • SSD wear-level monitoring (predictive failure analysis)
  • ASIC temperature thresholds (adaptive cooling control)
  • Line card CRC error tracking (preemptive fault detection)

​​Compatibility Validation​​

Integrated validation workflows ensure MIB consistency with FXOS platform bundles. Administrators can verify package integrity using the show validate-task 2.14(1.163) command in firmware mode.

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​
Firepower Chassis 4100/9300 (All SKUs)
FXOS Platform Bundle 2.14(1) or newer
SNMP Managers SolarWinds, Nagios, PRTG

​​Critical Notes​​:

  1. Requires FXOS 2.14(1) baseline installation before deployment
  2. Incompatible with Firepower 2100 Series or legacy ASA 5500-X platforms
  3. MIB compilation requires SNMPc 12.3+ or equivalent compiler tools
