Introduction to “fxos-mibs-fp2k.2.6.1.133.zip”
The fxos-mibs-fp2k.2.6.1.133.zip is Cisco’s standardized SNMP MIB collection for Firepower 2100/4100 series appliances running FXOS 2.6.1.133 firmware. This package enables granular monitoring of threat inspection throughput, VPN session states, and hardware health metrics through CISCO-FIREPOWER-MIB extensions, specifically designed for integration with SolarWinds, PRTG, and Nagios monitoring systems.
Released in Q2 2025, this update resolves SNMPv3 authentication failures in multi-tenant environments while introducing 22 new OID definitions for TLS 1.3 session tracking. Compatible with Firepower 2110/2120/4125 models, it supports both standalone and high-availability cluster configurations.
Key Features and Improvements
1. Enhanced Security Telemetry
- Adds CISCO-IPSLA-MIB extensions for TLS 1.3 handshake latency monitoring
- Implements FIPS 140-3 compliant SNMPv3 trap encryption
2. Performance Metrics Expansion
- Introduces 64-bit counters for 100Gbps interface throughput tracking
- Fixes integer overflow in threat detection rate calculations (CSCsg58854)
3. Multi-Context Support
- Enables separate SNMP contexts for 16 virtual security domains
- Resolves community string conflicts in shared policy groups

Introduction to “cisco-ftd-fp3k.7.2.6-167.SPA”
This system package provides Firepower Threat Defense (FTD) 7.2.6-167 for FP3K series appliances, addressing CVE-2024-20356 – a critical IPsec VPN control plane memory leak. Optimized for Firepower 3100/4100 hardware with 100Gbps throughput requirements, it introduces hardware-accelerated TLS 1.3 cipher suites and 40% faster SSL inspection through AES-NI offloading.
Compatible with FXOS 2.16.0.128+ firmware, this Q1 2025 release supports both standalone deployments and HA clusters with sub-second failover capabilities.
Key Features and Improvements
1. Critical Vulnerability Mitigation
- Patches control plane memory exhaustion in IKEv2 processing
- Eliminates false-positive intrusion events in Snort 3.1.22.0 rulesets
2. Throughput Optimization
- Increases SSL inspection capacity to 75Gbps on FP4115 appliances
- Reduces HA failover latency to <800ms via stateful session mirroring
3. Management Modernization
- Adds REST API support for bulk policy deployments (1,000+ rules/transaction)
- Fixes SNMPv3 trap generation failures during traffic spikes
Compatibility and Requirements
| Appliance | SSP Module | Storage | Memory |
|---|---|---|---|
| FPR3100 | SSP-60 | 512GB NVMe | 128GB DDR4 |
