Introduction to n9000-epld.10.2.6.M.img Software
This EPLD (Electrically Programmable Logic Device) firmware upgrades programmable logic components on Catalyst 9800-40/80 wireless controllers, resolving critical timing violations in 10GbE SFP+ interfaces first reported in Cisco Security Advisory cisco-sa-20250212-c9800. Certified for IOS XE 17.12.3+ deployments, it implements SHA-512 signature validation for FPGA configuration files to prevent unauthorized bitstream injection.
Compatible with hardware revisions C9800-CL-2.2+ and C9800-80-P2+, the firmware enables dynamic voltage scaling for power-constrained environments. Release notes dated March 2025 confirm backward compatibility with 10.2.5.L versions in mixed-stack deployments.
Key Features and Improvements
-
Multi-Threaded Programming
Enables parallel EPLD updates across 4 modules simultaneously, reducing maintenance windows by 62% compared to sequential flashing. -
FIPS 140-3 Compliance
Integrates NIST-certified AES-256-GCM encryption for JTAG configuration channels. -
Thermal Optimization
Implements adaptive clock throttling when chassis temperatures exceed 75°C, maintaining packet processing at 85% baseline performance. -
Error Correction
Adds SECDED (Single Error Correction, Double Error Detection) logic for configuration memory blocks.
Compatibility and Requirements
| Supported Hardware | Minimum IOS XE | FPGA Type |
|---|---|---|
| Catalyst 9800-40 | 17.12.3a | Xilinx XC7K325T |
| Catalyst 9800-80 | 17.12.4 | Xilinx XC7VX485T |
| Catalyst 9800-CL | 17.12.5 | Xilinx XC7A200T |
Critical Notes:
- Incompatible with legacy C9800-L-1.8 controllers
- Requires 8GB DRAM for error correction buffers

Introduction to n9000-epld.10.3.1.F.img Software
This EPLD update package addresses CRC miscalculations in Nexus 93180YC-FX3 fabric modules first identified in CSCwd98765. Validated with NX-OS 10.3(2)M releases, it introduces post-quantum Kyber-768 algorithms for secure FPGA authentication.
Designed for N9K-C93108TC-EX and N9K-C9336C-FX2 platforms, the firmware supports 400G-ZR coherent optics calibration through enhanced DSP clock synchronization. Release documentation confirms interoperability with 10.3.1.E versions in VDC configurations.
Key Features and Improvements
-
Optical Diagnostics
Enables real-time BER monitoring through integrated PRBS31 pattern generators. -
Power Optimization
Reduces idle power consumption by 18% through dynamic clock gating of unused SerDes lanes. -
Fabric Stability
Resolves multicast packet reordering issues in 64-node vPC+ topologies. -
Secure Boot
Implements Physically Unclonable Function (PUF) authentication for FPGA bitstreams.
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS | QSFP-DD Modules |
|---|---|---|
