Introduction to c8000aep-universalk9_noli.17.12.02.SPA.bin Software
The c8000aep-universalk9_noli.17.12.02.SPA.bin software package delivers Cisco IOS XE Cupertino 17.12.02 for the Catalyst 8000 Series Edge Platforms, designed for secure SD-WAN and hybrid cloud connectivity. This release focuses on operational resilience, with Cisco confirming 17.12.x as a long-term support (LTS) branch receiving extended maintenance until Q3 2026.
Compatible with Catalyst 8200/8300/8500 hardware platforms, this firmware enables enterprises to deploy high-performance edge routing with integrated threat defense. The “noli” designation confirms this build excludes cryptographic functionality for export-controlled regions.
Key Features and Improvements
1. Enhanced NAT Management
Implements CPU-based NAT translation limits through ip nat translation max-entries cpu commands, preventing resource exhaustion during traffic surges. This builds on the NAT redundancy optimizations introduced in earlier 17.12.x releases.
2. IPv6 Segment Routing Advancements
Expands data plane support for:
- Topology-Independent Loop-Free Alternate (TI-LFA) fast reroute
- Microloop avoidance during IS-IS convergence
- OAM traffic engineering capabilities
3. High Availability Reliability
Resolves critical FN74222 field notice issues where HA SSO pairs could experience configuration loss post-failover. The update introduces persistent-config file validation during synchronization.
4. Cisco SD-Routing Integration
Simplifies multi-WAN deployments with:
- Custom VRF creation for transport interfaces
- Enhanced path visibility through Network-Wide Path Insights (NWPI)
- Compatibility with Catalyst SD-WAN Manager 17.12.1+
Compatibility and Requirements
| Supported Hardware | Minimum DRAM | Software Dependencies |
|---|---|---|
| Catalyst 8200 Series | 8 GB | IOS XE 17.9.x or newer |
| Catalyst 8300 Series | 16 GB | Cisco DNA Center 2.3.5+ |
| Catalyst 8500 Series | 32 GB | SD-WAN vManage 20.12+ |
Critical Notes:
- Incompatible with legacy WAN modules using shared port adapters (SPA-8X1GE-V2)
- Requires Secure Boot validation for Trust Anchor Module (TAM) deployments
