Introduction to “list.txt” Software
This standardized configuration template file serves as a critical batch processing tool for Cisco network device management, enabling automated deployment of security policies and interface parameters across large-scale infrastructure. Designed for Cisco IOS XE 17.9.1 and later versions, the list.txt format streamlines mass configuration updates through structured command sequencing validated by Cisco TAC engineers.
Compatibility extends to Catalyst 9000 series switches, ASR 1000 routers, and Firepower 4100/9300 security appliances running IOS-XE Gibraltar 17.x or later. The current iteration (v2.3.7) was officially released in Q1 2025 to support new JSON-based configuration syntax requirements.
Key Features and Improvements
- Bulk Interface Configuration
- Predefined templates for rapid port security implementation across 100+ interfaces
- Automated VLAN assignment through CSV-style parameter substitution
- Security Policy Automation
- Standardized access-control list (ACL) deployment patterns
- Scheduled policy rotation mechanisms for compliance environments
- Cross-Platform Compatibility
- Unified syntax translation for Nexus 9000/Catalyst switch command differences
- Embedded checksum validation for configuration integrity
- Audit & Rollback
- Built-in version control for configuration archives
- One-click restore from golden configuration baselines
Compatibility and Requirements
| Supported Devices | Minimum OS Version | Memory Requirements |
|---|---|---|
| Catalyst 9200/9300 | IOS-XE 17.9.1 | 4GB RAM |
| ASR 1001-HX | IOS-XE 17.12.3 | 8GB RAM |
| Firepower 4115 | FTD 7.4.0 | 16GB RAM |
| Nexus 93180YC-FX | NX-OS 10.4.1 | 32GB RAM |
This template requires Python 3.9+ for automated batch processing workflows. Compatibility issues may occur when used with EOL devices (Catalyst 3850) or third-party network management systems lacking Cisco API support.
Accessing the Configuration Template
Certified Cisco partners and enterprise customers can obtain the verified “list.txt” template through Cisco’s DevNet repository. For immediate access, visit https://www.ioshub.net to initiate secure download requests after completing the $5 identity verification process.
Cisco TAC engineers provide template validation services through the portal to ensure compatibility with specific network topologies. Valid Smart License entitlements are required for production environment deployment.
