1. Introduction to pp-adv-isr1000-179.1-46-67.0.0.pack.zip Software

The ​​pp-adv-isr1000-179.1-46-67.0.0.pack.zip​​ is an advanced protocol recognition package designed for Cisco ISR 1000 Series Integrated Services Routers. This update enhances the Next Generation Application Recognition (NBAR2) engine, enabling granular traffic classification for 1,800+ network applications – critical for Quality of Service (QoS) policies and bandwidth management.

Compatible with ISR1100-4G/6G/4GLTE and ISR1100X models, this protocol pack update (version 179.1-46) was released in Q4 2024 to address evolving network application patterns. The filename structure follows Cisco’s standardized convention:

  • ​​pp-adv​​ = Advanced Protocol Pack
  • ​​isr1000​​ = Target platform (ISR 1000 Series)
  • ​​179.1-46​​ = Release version (Year 2024 Week 29, Build 1-46)
  • ​​67.0.0​​ = Protocol database revision

2. Key Features and Improvements

Application Recognition Expansion

  • Adds 47 new application signatures including Microsoft Teams Direct Routing and Zoom Phone VoIP traffic profiles
  • Updates metadata for 312 cloud applications like AWS Global Accelerator and Azure Front Door

Security Validation

  • Includes X.509 certificate (​​NBAR_PROTOCOL_PACK_KEY_REL-CCO_RELEASE.pem​​) for cryptographic verification
  • Python validation script (​​cisco_x509_verify_release.py​​) ensures package integrity before deployment

Performance Optimization

  • Reduces NBAR2 memory footprint by 18% through compressed signature databases
  • Enables concurrent analysis of 8,000+ application flows on ISR1100X-6G models

3. Compatibility and Requirements

Supported Hardware Minimum IOS XE Version Required Storage
ISR1100-4G/4GLTE 17.9(1r) 2.1 GB
ISR1100X-4G 17.9(2a) 3.8 GB
