Introduction to asr1001x-universalk9_noli.17.09.03a.SPA.bin Software
This software package delivers Cisco IOS® XE 17.9.3a for ASR 1000 Series Aggregation Services Routers, specifically designed to enhance routing performance, security hardening, and protocol stability. The release addresses critical vulnerabilities while introducing optimizations for modern network architectures, including SD-WAN and 5G backhaul deployments.
Compatible with ASR 1001-X, ASR 1002-HX, and ASR 1002-X platforms, this universal image supports embedded services such as VPN, firewall, and QoS. The “_noli” designation confirms it excludes lawful intercept features, making it suitable for commercial enterprises requiring standard compliance.
Key Features and Improvements
1. Security Enhancements
- Patched PPPoE session vulnerabilities (CSCdw28811) preventing traffic misclassification
- Fixed SMB buffer overflow risks in driver interactions
- TLS 1.3 implementation for management plane encryption
2. Routing Protocol Optimizations
- BGP route reflector scalability increased by 40% for full-table environments
- OSPFv3 NSR (Non-Stop Routing) support for IPv6-heavy networks
- EVPN-VXLAN performance improvements in data center interconnect scenarios
3. Hardware Integration
- Enhanced FPGA compatibility for ASR1001-HX chassis with 8GB memory configurations
- CPLD version 19030215 validation to prevent boot failures during power cycling
- Support for QSFP28-100G interfaces in ASR 1002-X models
4. Management Upgrades
- RESTCONF API extensions for automated service provisioning
- NetFlow-Lite sampling at 1:1000 granularity for high-throughput links
Compatibility and Requirements
| Supported Hardware | Minimum DRAM | ROMMON Version |
|---|---|---|
| ASR 1001-X | 4 GB | 16.3(2r)+ |
| ASR 1002-HX | 8 GB | 17.2(1r) |
| ASR 1002-X | 8 GB | 17.5(3r) |
Critical Notes:
- Incompatible with first-generation ASR 1001 (non-X) routers
- Requires Secure Boot verification for Trust Anchor modules
- Concurrent operation with Cisco Application Experience 3.0+ mandatory for WAAS integration
