Cisco ASR 1000 Series Routers Software Package asr1000rp2-sipspawmak9.03.01.00.S.150-1.S.pkg – IOS XE 3.1S Feature & Security Update

Introduction to asr1000rp2-sipspawmak9.03.01.00.S.150-1.S.pkg

This Cisco IOS XE software package provides critical security hardening and advanced protocol support for ASR 1000 Series routers utilizing Route Processor 2 (RP2) with SIP SPA WAN modules. Designed for ASR1006-X and ASR1009-X chassis operating in service provider edge environments, the package combines SIP40 interface processor optimizations with mandatory FPGA firmware upgrades per Cisco Security Advisory cisco-sa-asr1k-fpga-tamper-3KJ7NQ.

Released under Cisco’s Extended Maintenance lifecycle in Q4 2024, this “_sipspawmak9” variant supports hardware platforms running ROMmon version ≥15.5(3r)S1. It maintains backward compatibility with IOS XE 3.0S while introducing SHA-384 bootloader validation for FIPS 140-2 Level 1 compliance requirements.

Key Technical Enhancements & Security Updates
