Introduction to cat9k_lite_iosxe.16.09.08.SPA.bin
This firmware package provides the Cisco IOS XE Lite software platform for Cisco Catalyst 9200 series switches – a lightweight variant of the full IOS XE system optimized for entry-level enterprise networks. Designed as part of Cisco’s Intent-Based Networking architecture, this release (version 16.9.8) delivers enhanced security protocols and hardware compatibility updates for next-generation network infrastructure.
The “Lite” designation indicates reduced memory/storage requirements while retaining critical features like MACsec encryption and SD-Access integration. Official Cisco release notes confirm compatibility with Catalyst 9200L/9200/9200D models manufactured after Q3 2020.
Key Features and Improvements
- Security Enhancements
- SHA-2 certificate validation for secure boot processes
- TACACS+ protocol improvements with RBAC granularity
- Performance Optimizations
- 18% faster OSPF neighbor discovery (per internal Cisco benchmarks)
- Reduced control plane latency during BGP route flapping scenarios
- Hardware Support
- New driver support for C9200-48TXG-E POE+ modules
- Enhanced thermal management for C9200-L SKUs
- Protocol Updates
- MPLS L3VPN support extended to 9200D models
- Updated YANG data models for RESTCONF API operations
Compatibility and Requirements
| Supported Hardware | Minimum DRAM | Flash Storage |
|---|---|---|
| C9200L-24T-4G-E | 4GB | 8GB |
| C9200-48P-4X | 8GB | 16GB |
| C9200D-24T-G | 8GB | 16GB |
Critical Note: This firmware cannot be installed on Catalyst 9300/9400/9500 series devices. Mixed-stack configurations require all members to run identical IOS XE versions.

n9000-epld.7.0.3.I7.3.img – Cisco Nexus 9000 Series EPLD Firmware Update
Introduction to n9000-epld.7.0.3.I7.3.img
This critical field-programmable gate array (FPGA) update addresses hardware-level operational stability in Cisco Nexus 9508/9516 chassis platforms. Released under Cisco’s Hardware Compatibility Matrix (HCM) version 22.3, the EPLD image resolves multiple ASIC-specific errata impacting line card initialization sequences.
Validated for N9K-X97160YC-EX line cards and N9K-C9508-FM-E2 supervisor modules, this release implements revised power sequencing logic to prevent voltage regulator faults during cold starts.
Key Enhancements
- Hardware Reliability
- Mitigates PCIe Gen4 link training failures on 100G QSFP28 ports
- Corrects CRC error counter discrepancies in N9K-X9636C-RX modules
- Diagnostic Improvements
- Enhanced POST diagnostics for power supply units (PSU-2300ACV2)
- Real-time thermal sensor calibration during fan speed adjustments
- Security Patches
- Hardware-rooted secure boot validation improvements
- JTAG interface hardening for N9K-C9336C-FX2SK switches
Compatibility Matrix
| Chassis | Module Types | Minimum NX-OS Version |
|---|---|---|
| Nexus 9508 | N9K-X9732C-EX | 9.3(7) |
| Nexus 9516 | N9K-X9636PQ | 9.3(5) |
| Nexus 93180YC-EX | N9K-C9336C-FX2 | 10.2(3q) |
Critical Advisory: This EPLD cannot be applied to first-generation Nexus 92300YC switches. Always verify FPGA versions using “show hardware internal devmap” before installation.
