Introduction to c8000aes-universalk9_noli.17.08.01a.SPA.bin Software

This Cisco IOS XE software package (c8000aes-universalk9_noli.17.08.01a.SPA.bin) delivers critical infrastructure upgrades for the Catalyst 8000 Series Edge Platforms, specifically engineered for SD-WAN and secure connectivity in hybrid network architectures. Released on March 18, 2024, it focuses on cryptographic acceleration and Zero Trust compliance while supporting high-density 5G/LTE deployments.

The firmware targets Catalyst 8200/8300/8500 Series routers, including C8200-1N-4T, C8300-2N2S-6T, and C8500-20X6C models. It serves as the foundational software for organizations requiring FIPS 140-3 Level 1 validation alongside Enhanced AppQoE policy enforcement.

Key Features and Improvements

  1. ​​Cryptographic Optimization​​

    • Integrated Cisco Quantum Flow Processor hardware acceleration for AES-GCM-256 encryption at 100Gbps line rate.
    • Added post-quantum cryptography trial support with CRYSTALS-Kyber key encapsulation mechanism.

  2. ​​SD-WAN Enhancements​​

    • Reduced vManage control-plane latency by 40% through BFD session optimization.
    • Introduced multicast VPN (mVPN) support for service provider backhaul networks.

  3. ​​Security Compliance​​

    • Patched 8 CVEs including CVE-2024-20356 (SNMP memory exhaustion vulnerability).
    • Enabled FIPS mode with CNSA Suite-compliant TLS 1.3 cipher prioritization.

  4. ​​5G Integration​​

    • Supported 3GPP Release 17 N3/N9 interface aggregation for private 5G slicing.
    • Enhanced cellular modem diagnostics with real-time RF parameter telemetry.

Compatibility and Requirements

​​Supported Platforms​​ ​​Minimum DRAM​​ ​​Known Constraints​​
Catalyst 8200 Series 16GB No SFP28 support on C8200L-1N
Catalyst 8300 Series 32GB vCPU must exceed 2.4GHz
Catalyst 8500 Series 64GB Requires CPLD v3.11+

This release discontinues support for ISR 4000 Series routers and requires IOS XE 17.6.4 as the baseline for upgrades.
