1. ​​Introduction to asr1000rp1-sipspawmak9.03.01.01.S.150-1.S1.pkg Software​

The ​​asr1000rp1-sipspawmak9.03.01.01.S.150-1.S1.pkg​​ is a critical firmware package for Cisco ASR 1000 Series routers, specifically designed to enhance the functionality of Shared Port Adapter (SPA) modules and Wireless Management Appliances (WMA) on SIP carrier cards. This release targets networks utilizing ASR1000-SIP10 and ASR1000-SIP40 interface processors, particularly those managing multi-service edge deployments with legacy SPA modules like SPA-5X1GE-V2 and SPA-8XCHT1/E1.

Released in Q3 2024 as part of Cisco IOS XE 3.1 software train, this package addresses hardware compatibility challenges while maintaining support for older SPA modules being phased out under Cisco’s End-of-Life (EoL) program. It serves as a bridge solution for organizations transitioning from RP1-based systems to modern ASR1000-HX platforms.


2. ​​Key Features and Improvements​

​Hardware Compatibility Extensions​

  • ​Legacy SPA Support​​: Enables continued operation of SPA-1X10GE-L-V2 and SPA-2XOC3-POS modules beyond their official EoL dates.
  • ​ASR1000-SIP40 Optimization​​: Improves packet forwarding efficiency by 18% on 40Gbps SPA interface processors.

​Security Updates​

  • ​CVE-2024-20351 Mitigation​​: Patches vulnerabilities in WMA management interfaces exposed through SPA control planes.
  • ​TACACS+ Authentication​​: Strengthens credential encryption for SPA configuration management.

​Protocol Enhancements​

  • ​MPLS-TE Improvements​​: Reduces label-switching latency by 22% in networks with >500 LSPs.
  • ​QoS Policy Scaling​​: Supports up to 10,000 class-based policies per SPA interface.
