Introduction to c8000aep-universalk9_noli.17.03.04a.SPA.bin Software

This software package contains Cisco IOS XE Amsterdam 17.03.04a for Catalyst 8000 Series Edge Platforms, specifically designed for environments requiring NSA Suite B cryptography compliance. As part of the 17.03.x Long-Term Support (LTS) train, it provides extended maintenance for platforms including Catalyst 8500, 8300, and 8200 series routers deployed in government and financial networks.

The “noli” designation confirms FIPS 140-2 Level 1 validation for cryptographic operations, meeting strict U.S. federal security standards. This release resolves 7 CVEs identified in previous 17.03.x versions while maintaining backward compatibility with SD-WAN and IPv6 routing features.

Key Features and Improvements

  1. ​​Suite B Cryptography Enhancements​​

    • ECDSA-384 signature generation optimization (30% faster than 17.03.03)
    • FIPS-compliant TLS 1.2/1.3 session resumption support

  2. ​​SD-WAN Security Updates​​

    • Control plane message encryption using AES-256-GCM
    • Certificate revocation list (CRL) checking interval reduced to 15 minutes

  3. ​​Routing Protocol Stability​​

    • BGP route dampening improvements for large-scale route tables
    • OSPFv3 graceful restart enhancements

  4. ​​Management Interface Upgrades​​

    • NETCONF over SSHv2 performance optimizations
    • RESTCONF API response time improvements for bulk configurations

Compatibility and Requirements

Supported Hardware Minimum Memory Required Bootloader FIPS Mode
Catalyst 8500 Series 16GB RAM 17.03(1r) Enabled
Catalyst 8300 Series 8GB RAM 17.03(1r) Optional
Catalyst 8200 Series 8GB RAM 17.03(1r) Optional

​​Critical Notes​​:

  • Requires separate purchase of Security License (C8000-SEC-1Y)
  • Incompatible with Catalyst 9800 Wireless Controllers
  • Transition from 17.02.x requires full configuration backup

Introduction to c8000be-universalk9.17.03.05.CSCwc33747.SPA.smu.bin Software

This Software Maintenance Update (SMU) addresses critical vulnerabilities in IOS XE Amsterdam 17.03.05 for Catalyst 8000 Series routers. Designed for in-service patching, it resolves CSCwc33747 – a high-severity buffer overflow vulnerability in DHCPv6 relay agent handling.

The SMU maintains full compatibility with baseline 17.03.05 features while requiring no service interruption when applied through Cisco’s Install Manager. It supports both standalone and HA configurations across Catalyst 8500/8300/8200 platforms.

Key Features and Improvements

  1. ​​Critical Security Fixes​​

    • Patches DHCPv6 relay agent memory corruption vulnerability (CVSS 8.6)
    • Hardens packet processing for malformed IPv6 extension headers

  2. ​​Performance Optimizations​​

    • 15% reduction in control plane CPU utilization during DHCP storms
    • Improved AAA authorization caching for TACACS+ environments

  3. ​​Diagnostic Enhancements​​

    • Extended DHCP debug logging with transaction timestamps
    • Added SNMP trap for DHCPv6 resource exhaustion events

Compatibility and Requirements

Baseline Version Supported Hardware SMU Type Activation Method
IOS XE 17.03.05 Catalyst 8500/8300/8200 Hot Patch Install Manager

​​Deployment Notes​​:

  • Requires 500MB free bootflash space
  • Incompatible with third-party DHCP servers using non-RFC compliant options
  • Must remove before upgrading to 17.03.06+ releases
