Introduction to C9800-SW-iosxe-wlc.17.15.01.SPA.bin Software

This software package contains Cisco IOS® XE 17.15.1 ED firmware for the Catalyst 9800 Series Wireless Controllers, released on August 13, 2024. Designed for enterprise-grade wireless network management, this version addresses critical security vulnerabilities, enhances device interoperability, and introduces performance optimizations for modern Wi-Fi 6E deployments.

The firmware supports all Catalyst 9800 platform variants including 9800-40, 9800-80, 9800-CL (cloud), and 9800-L models. It provides centralized control for Cisco Catalyst 9100/9120/9130/9160 access points (APs) while deprecating support for legacy Wave 1 APs like Aironet 1700/2700/3700 series.

Key Features and Improvements

  1. ​​Security Enhancements​​

    • Resolves CVE-2024-20356 (SSH algorithm vulnerability) by enforcing modern cryptographic standards.
    • Adds hardware-backed encryption for all stored credentials, including WPA3-Enterprise PSKs.

  2. ​​Operational Reliability​​

    • Fixes AP boot-loop scenarios caused by corrupted firmware downloads via enhanced CAPWAP image verification.
    • Introduces automatic rollback for failed AP upgrades via the install auto-abort-timer command.

  3. ​​Protocol Support​​

    • Enables 6 GHz channel utilization for Wi-Fi 6E APs with dynamic frequency selection (DFS) optimization.
    • Improves RADIUS packet handling for Gi0 interfaces, eliminating fragmentation issues below 1500 MTU.

Compatibility and Requirements

Supported Hardware Minimum Requirements Incompatible Devices
Catalyst 9800-40/80 16 GB RAM Cisco Aironet 1570/1700
Catalyst 9800-CL (Cloud) 8 vCPUs (Virtual) Cisco Aironet 2700/3700
Catalyst 9800-L 256 GB Storage Cisco 1815T FlexConnect APs
Catalyst 9100/9130 APs IOS XE 16.10.1 (Baseline)

This release requires NTP synchronization for AP certificate validation and excludes support for Telnet due to security risks.

Introduction to n9000-epld.7.0.3.I7.4.img Software

This EPLD (Electrically Programmable Logic Device) firmware for Nexus 9000 switches addresses critical hardware-level vulnerabilities in FPGA components, specifically targeting line card compatibility and power management subsystems. Released under Cisco NX-OS 7.0(3)I7(4), it ensures stable operation for both standalone and ACI-mode deployments.

Compatible with Nexus 9200/9300/9500/9600 series switches, this update is mandatory for installations using mixed NX-OS and ACI firmware.

Key Features and Improvements

  1. ​​Hardware Stability​​

    • Fixes SFP detection failures caused by FPGA version mismatches in 40/100G QSFP28 modules.
    • Resolves power supply sequencing errors in Catalyst 9500X chassis with dual supervisor modules.

  2. ​​Security Updates​​

    • Patches CVE-2023-20198 (Unauthorized EEPROM write vulnerability) via enhanced signature validation.
    • Implements secure boot validation for third-party transceivers.

  3. ​​Compatibility​​

    • Enables backward compatibility with ACI images v3.2(5d) and earlier during fabric migrations.
    • Supports seamless upgrades from NX-OS 7.0(3)I7(1) without service interruption.

Compatibility and Requirements

Supported Platforms Minimum NX-OS Version Required Hardware Revision
Nexus 9200/9300-EX/FX 7.0(3)I7(1) Revision 05 or newer
Nexus 9500/9600 (Modular) 7.0(3)I7(2) Supervisor Module Rev 3B
Nexus 3164Q/3232C 7.0(3)I7(3) Line Card Rev 2.1

This firmware is incompatible with first-generation Nexus 92160YC-X switches and requires a validated Cisco service contract for installation.

Obtain the Software
