Introduction to “fxos-mibs-fp9k-fp4k.2.12.0.31.zip” Software
This MIB (Management Information Base) package provides standardized SNMP monitoring templates for Cisco Firepower 4100/9300 Series appliances running FXOS 2.12.x. Released in Q1 2025, version 2.12.0.31 enhances compatibility with third-party network monitoring systems like SolarWinds and Nagios Core. The package contains 48 predefined OID groups covering chassis health, thermal metrics, and power supply status.
Officially curated by Cisco’s Firepower Management Center team, it supports real-time monitoring of critical components including supervisor modules, FPGA firmware revisions, and SSD wear-leveling statistics. The MIB definitions align with RFC 4293 standards for entity-based SNMP monitoring.
Key Features and Improvements
1. Enhanced Hardware Visibility
- Adds 12 new OIDs for monitoring Firepower 2100/3100 series expansion modules
- Supports dynamic tracking of dual supervisor failover events
2. Security Compliance Updates
- Implements SHA-256 authentication for SNMPv3 trap destinations
- Resolves CVE-2025-0317 (SNMP credential leakage during chassis reboots)
3. Protocol Optimization
- Reduces SNMP polling latency by 40% through OID tree restructuring
- Introduces bulk-data retrieval support for power metrics (RFC 3430)
