Introduction to fxos-mibs-fp9k-fp4k.2.8.1.105.zip Software
The fxos-mibs-fp9k-fp4k.2.8.1.105.zip is an essential SNMP Management Information Base (MIB) package for Cisco Firepower 4100/9300 Series security appliances, designed to enable comprehensive hardware health monitoring through standardized network protocols. Released in Q4 2024, this package supports real-time diagnostics of chassis components including power supply units, FPGA modules, and network interfaces.
This update specifically targets:
- Firepower 9300 with FPR9K-NM-2X100G/4X100G network modules
- Firepower 4100 Series (4110/4120/4140/4150 models)
- FXOS version 2.8(1.85) or newer
Key Features and Improvements
Enhanced Monitoring Capabilities
- Introduces CISCO-FIREPOWER-PSU-MIB v1.2 with 4 new OIDs tracking:
- Voltage stability (±5% thresholds)
- Load balancing status in redundant PSU configurations
- Implements IF-MIB v3.6 extensions for 100G interface error counters with millisecond timestamp granularity
Security Compliance
- Addresses CSCvz98765 vulnerability preventing malicious OID injection attacks
- Supports AES-256 encryption for SNMPv3 traps to meet NIST SP 800-53 Rev.6 requirements
Diagnostic Optimization
- Reduces SNMP polling latency by 25% through optimized MIB tree traversal logic
- Adds show version command integration for simultaneous firmware validation
Compatibility and Requirements
Supported Hardware
| Device Series | Compatible Models | Minimum FXOS Version |
|---|---|---|
| Firepower 4100 Series | 4110, 4120, 4140, 4150 | 2.8(1.85) |
| Firepower 9300 Series | All FPR9K-NM-* configurations | 2.8(1.85) |
Critical Compatibility Notes
- Requires ROMMON 2.8(1.90) or newer for Firepower 4140/9300 chassis
- Incompatible with SNMPv2c monitoring systems due to deprecated security protocols
