Introduction to fxos-mibs-fp9k-fp4k.2.9.1.131.zip

This MIB (Management Information Base) package is a critical component for monitoring and managing Cisco Firepower 4100 and 9300 series security appliances through SNMP protocols. Released alongside FXOS 2.9.1 firmware updates, it contains standardized definitions for device status tracking, fault detection, and performance metrics collection.

The package specifically supports two SNMP traps documented in CISCO-FIREPOWER-AP-NOTIFS-MIB:

  • ​​cfprApFaultActiveNotif​​ (OID .1.3.6.1.4.1.9.9.826.2.0.1) for active system faults
  • ​​cfprApFaultClearNotif​​ (OID .1.3.6.1.4.1.9.9.826.2.0.2) for fault resolution alerts.

Cisco recommends installing this version after upgrading to FXOS 2.9.1 or later to ensure compatibility with network management systems like Cisco Prime or third-party monitoring tools.

Key Features and Improvements

  1. ​​Enhanced SNMP Monitoring​​
    Adds support for tracking hardware health metrics of Firepower 4100/9300 chassis components, including power supplies and fan modules.

  2. ​​Security Compliance Updates​​
    Aligns with latest IETF RFC standards for SNMPv3 encryption protocols, addressing potential vulnerabilities identified in previous MIB versions.

  3. ​​Trap Optimization​​
    Reduces false-positive alerts through refined threshold definitions for temperature sensors and memory utilization monitoring.

  4. ​​FPGA Compatibility​​
    Supports firmware packages containing critical hardware controller updates like fxos-k9-fpr4k-fpga.1.06.SPA and fxos-k9-fpr9k-fpga.1.06.SPA.

Compatibility and Requirements

Supported Hardware Minimum FXOS Version Supported NMS Platforms
Firepower 4115/4125/4145/4155 2.9.1 Cisco Prime 3.10+
Firepower 9300 (SM-36/44/56) 2.9.1 SolarWinds NPM 2020.2+
Firepower 4100 Series 2.9.1 Nagios XI 5.8+

​​Critical Notes​​:

  • Incompatible with Firepower 2100/3100 models requiring separate MIB packages
  • Requires SNMP service enabled on FXOS 2.9.1+ through CLI or Firepower Device Manager
  • MIB compilation errors may occur if paired with deprecated RFC MIBs older than 2018 revisions
