​​Introduction to fxos-mibs-fp4200.2.14.1.167.zip​​

This SNMP MIB package enables granular hardware monitoring for Cisco Secure Firewall 4200 Series appliances running FXOS 2.14(x). Designed for enterprise network operations teams, it provides standardized telemetry for chassis health metrics critical to maintaining uptime in high-availability environments.

The package specifically supports:

  • ​​Firepower 4200 Models​​: 4215/4235/4245/4255
  • ​​FXOS Versions​​: 2.14(1) or newer
  • ​​SNMP Managers​​: Cisco Prime Infrastructure, SolarWinds, Zabbix

Cisco officially released this update on April 28, 2025, addressing SNMPv3 compatibility gaps identified in earlier MIB packages. It introduces enhanced monitoring capabilities for power distribution units (PDUs) and environmental sensors – essential for data center infrastructure management (DCIM).

​​Key Features and Improvements​​

​​Advanced Hardware Diagnostics​​

New OIDs monitor:

  • PSU load balancing efficiency (predictive capacity planning)
  • NVMe SSD endurance metrics (wear-level percentage)
  • Thermal margin thresholds for ASICs (adaptive cooling triggers)

​​SNMPv3 Security Enhancements​​

Implements SHA-512 authentication and AES-256-GCM encryption for SNMPv3 traps, exceeding FIPS 140-3 Level 2 requirements. This ensures secure telemetry transmission in regulated industries like healthcare and finance.

​​Validation Framework Integration​​

Supports automated MIB validation through FXOS CLI using:

show validate-task 2.14(1.167)

This command cross-checks package integrity against Cisco’s cryptographic manifest system, reducing deployment risks in zero-trust networks.

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​
Firepower Chassis 4200 Series (All variants)
FXOS Platform Bundle 2.14(1) minimum
SNMP Protocol v2c/v3 with 2048-bit RSA keys
Management Interface Cisco FMC 7.6+ or API Gateway

​​Critical Notes​​:

  1. Requires FXOS 2.14(1) baseline installation prior to deployment
  2. Incompatible with Firepower 3100 Series or ASA 5500-X legacy platforms
  3. MIB compilation requires Net-SNMP 5.9+ or equivalent toolchains
