Introduction to c8000aep-universalk9_noli.17.06.01a.SPA.bin Software

This firmware delivers Cisco IOS XE 17.06.01a for Catalyst 8000 Series Edge Platforms (8200/8300/8500 hardware models) and C8000V virtual routers, specifically designed for enterprise WAN edge deployments requiring non-linecard-impacting (NOLI) upgrades. Released in Q2 2024, it resolves 6 CVEs identified in earlier versions including DHCPv6 memory allocation vulnerabilities and SNMPv3 buffer overflow risks. The package maintains backward compatibility with Cisco Catalyst SD-WAN Manager 20.6+ for unified hybrid cloud management.

Key Features and Improvements

  • Optimized HA synchronization using ip nat settings redundancy optimized-data-sync

​​2. IPv6 Segment Routing Enhancements​​

  • IS-IS microloop avoidance (<500ms reconvergence)
  • Topology-independent LFA fast reroute
  • OAM traffic engineering diagnostics improvements

​​3. Security Hardening​​

  • TLS 1.3 cipher suite compliance with FIPS 140-3 standards
  • Mitigated buffer overflow in SMB protocol stack

​​4. SD-WAN Optimization​​

  • Multi-WAN interface support through custom VRF configurations
  • Network-Wide Path Insights (NWPI) v2.0 for traffic visualization
