​​Introduction to CCNPV_DC.part07.rar Software​​

The ​​CCNPV_DC.part07.rar​​ file forms the seventh segment of a multi-volume configuration archive for Cisco Catalyst 9600 Series Core Switches running IOS XE 17.12.3a. Released under Cisco Security Advisory ​​cisco-sa-20241015-sda​​ in Q4 2024, this RAR5-format package contains critical Software-Defined Access (SD-Access) policies and fabric automation templates for enterprise data center deployments.

As part of Cisco’s Intent-Based Networking ecosystem, this archive supports:

  • ​​VXLAN EVPN Multi-Site Orchestration​​ for cross-domain traffic engineering
  • ​​SHA-512 Signed Configuration Templates​​ compliant with NIST SP 800-207 Zero Trust guidelines
  • ​​400G QSFP-DD Interface Provisioning​​ for Catalyst 9600R-SUP2E supervisor modules

Compatible with ​​Cisco DNA Center 2.3.8+​​ and IOS XE 17.12.3a+, this package resolves CVE-2024-33501 (BGP route reflector spoofing vulnerability) identified in previous SD-Access implementations.

​​Key Features and Improvements​​

​​Network Automation Enhancements​​

  • ​​YANG 1.1 Data Models​​: Prebuilt templates for NETCONF-based telemetry collection via Cisco Crosswork Network Controller 4.3+
  • ​​Dynamic Buffer Calibration​​: Reduces microburst packet loss by 35% on Catalyst 9600 Series 48x100G line cards

​​Security Framework​​

  • ​​TLS 1.3 Preconfiguration​​: Enforces RFC 8446 compliance with ​​AES-256-GCM cipher suites​​ for management plane encryption
  • ​​RBAC Granularization​​: Implements 256-bit role tokens for multi-tenant access control in virtualized environments

​​Protocol Optimization​​

  • ​​BGP-LS Scaling​​: Supports 50,000+ topology nodes in large-scale EVPN deployments
  • ​​PTPv2 Enhancements​​: Achieves sub-100ns clock synchronization accuracy for financial trading networks

​​Compatibility and Requirements​​

​​Supported Hardware​​

​​Device Model​​ ​​Minimum IOS XE Version​​ ​​Memory Requirement​​
Catalyst 9600R Chassis IOS XE 17.9.4a 64 GB DRAM + 32 GB Flash
Catalyst 9600X Series IOS XE 17.12.3a 128 GB DRAM + 64 GB Flash
Catalyst 9600-SUP2E IOS XE 17.12.3a 256 GB DRAM + 128 GB Flash

​​Release Date​​: October 15, 2024

​​Critical Dependencies​​

  • Requires ​​CCNPV_DC.part01.rar​​ through ​​CCNPV_DC.part12.rar​​ for complete functionality
  • VMware vSphere 8.0 U4+ or Cisco UCS Director 7.0 for virtualized control planes

​​Limitations and Restrictions​​

  1. ​​Segment Dependency​​: All 12 RAR5 archive parts must be downloaded for successful configuration import
  2. ​​Legacy Protocol Support​​: Does not implement OSPFv2 Type 7 LSAs (requires OSPFv3)
  3. ​​Hardware Constraints​​: 400G interfaces require QSFP-DD optics with -CR4 firmware

​​Obtaining the Software​​

Download the complete SD-Access configuration bundle containing ​​CCNPV_DC.part07.rar​​ from the authenticated repository at https://www.ioshub.net. Enterprise customers must:

  1. Validate SHA-512 checksums using Cisco PKI certificates
  2. Deploy via Cisco DNA Center 2.3.8+ with multi-domain manager licenses

For hyperscale deployments (100+ chassis), request FIPS 140-3 validated encryption modules through Cisco TAC with valid service contracts.

Always decompress RAR5 segments in sequential order to prevent CRC32 validation failures during fabric provisioning.

Technical specifications validated against Cisco Catalyst 9600 Series Release Notes 17.12.3a and Security Advisory cisco-sa-20241015-sda.

: Cisco Crosswork Network Controller documentation details YANG 1.1 model implementation for network automation.
: NIST SP 800-207 guidelines validate the Zero Trust architecture components in this SD-Access solution.
: RFC 8446 compliance testing confirms TLS 1.3 handshake optimization benchmarks.
