Introduction to asr1002x-universalk9_noli.17.03.06.SPA.bin Software
This Cisco IOS® XE 17.3.6 universal software image delivers critical updates for the ASR 1002-X Series Aggregation Services Routers, designed for high-performance enterprise WAN and service provider edge deployments. The “_noli” suffix confirms the exclusion of lawful intercept features, making it ideal for commercial networks requiring FIPS 140-3 compliance without government surveillance capabilities.
Released in Q1 2025, this version resolves FPGA initialization failures reported in earlier 17.3.x releases while supporting advanced features like 200Gbps throughput on ASR1002X-36G-HA-K9 models. Compatible hardware includes ASR1002X-5G-K9, ASR1002X-20G-SECK9, and ASR1002X-36G-HA-K9 variants with ESP40/ESP200 modules.
Key Features and Improvements
1. Security Hardening
- Patched CVE-2025-20180 XSS vulnerabilities in RESTCONF API interfaces
- Enhanced Secure Boot validation for FPGA/CPLD programmable logic images
- TLS 1.3 enforcement for all management plane communications
2. Routing Protocol Optimization
- 35% improvement in BGP convergence time (>800k IPv6 routes)
- EVPN-VXLAN gateway capacity expanded to 8,000 virtual networks
- OSPFv3 Non-Stop Routing (NSR) support for metro-core deployments
3. Hardware Integration
- Validated QSFP-40G interface compatibility on ASR1002X-20G models
- Enhanced error correction for ESP200 modules under 300Gbps throughput
- CPLD version 19030215 certification to prevent cold boot failures
4. Telemetry & Automation
- RESTCONF API extensions for zero-touch MPLS VRF provisioning
- Real-time FPGA temperature monitoring via NETCONF/YANG models
