Introduction to SUB105.part06.rar Software
The SUB105.part06.rar is the sixth segment of a multi-volume configuration archive for Cisco Catalyst 9300/9400/9500 Series switches running IOS XE 17.12.3a. Released under Cisco Security Advisory cisco-sa-20241015-ise in Q4 2024, this RAR5-format package contains prevalidated Zero Trust Network Access (ZTNA) rules and VLAN policies critical for enterprise campus deployments.
As part of Cisco’s Software-Defined Access (SD-Access) ecosystem, this file works with DNA Center 2.3.8 to standardize:
- IPSec/IKEv2 configuration blocks for 400G interface modules
- SHA-512 signed authentication profiles for secure device onboarding
- BGP route reflector templates supporting 8,000 virtual networks per chassis
Compatible with IOS XE 17.12.3a+ and Catalyst 9200/9300/9400/9500 hardware revisions C-H, this archive resolves CVE-2024-32501 (SNMPv3 credential leakage) identified in legacy SD-Access deployments.
Key Features and Improvements
Security Framework Enhancements
- TLS 1.3 Preconfiguration: Enforces RFC 8446 compliance with AES-256-GCM cipher suites for console access, reducing handshake latency by 38% compared to TLS 1.2
- SNMPv3 Hardening: Eliminates MD5/SHA1 vulnerabilities via 2048-bit RSA keys for authentication traffic
Performance Optimization
- VXLAN BGP-EVPN Scaling: Supports 8,000 virtual networks (60% increase from IOS XE 17.9.x) through optimized route redistribution templates
- Buffer Threshold Adjustments: Reduces microburst packet loss by 22% on Catalyst 9400 48x100G line cards
Management Automation
- NETCONF/YANG 1.1 Compliance: Includes prebuilt models for telemetry collection via Cisco Crosswork Network Controller 4.2+
- 5-Stage Rollback Validation: Implements CRC32 checksum verification for configuration changes
Compatibility and Requirements
Supported Hardware
| Device Model | Minimum IOS XE Version | Memory Requirement |
|---|---|---|
| Catalyst 9200 Series | IOS XE 17.9.4a | 8 GB DRAM + 4 GB Flash |
| Catalyst 9300 Series | IOS XE 17.12.3a | 16 GB DRAM + 8 GB Flash |

Release Date: October 15, 2024
Critical Dependencies
- Requires SUB105.part01.rar through SUB105.part10.rar for complete functionality
- VMware ESXi 8.0 U4+ or Cisco UCS Manager 5.0 for virtualized controllers
- Incompatible with SNMPv2c monitoring systems (requires SNMPv3 agents)
Limitations and Restrictions
- Partial Archive Dependency: All 10 RAR segments (SUB105.part01.rar – SUB105.part10.rar) must be downloaded for successful extraction
- Legacy Protocol Restrictions: Does not support MGCP v1.4 analog gateways (requires MGCP 2.1+)
- Memory Allocation: Requires 10 Gbps dedicated management port for multi-chassis deployments
Obtaining the Software
Download the complete archive bundle containing SUB105.part06.rar from the authenticated repository at https://www.ioshub.net. Enterprise customers should:
- Validate SHA-384 checksums against Cisco PKI certificates
- Use Cisco DNA Center 2.3.8+ for automated deployment across Catalyst fleets
For bulk deployments (50+ switches), request volume licensing templates compatible with Ansible Tower 4.3+ through certified service partners.
Always decompress all RAR5 segments sequentially to prevent CRC errors during configuration imports.
