Introduction to term70.default.loads Software
The term70.default.loads configuration template provides standardized traffic distribution policies for Cisco Catalyst 9200 Series switches running IOS-XE Amsterdam 17.12.x. Designed to optimize layer 3/4 load balancing in enterprise networks, this template implements Cisco’s Enhanced Object Tracking (EOT) algorithms to dynamically redistribute traffic across multiple WAN links and service modules.
Released in Q2 2025 under Cisco’s Long-Term Support (LTS) program, version 70 enhances compatibility with SD-WAN overlays while maintaining backward compatibility with legacy routing protocols. The “.default.loads” suffix indicates its role as a baseline configuration for networks requiring automated traffic engineering without custom scripting.
Key Features and Improvements
This template introduces critical enhancements for multi-path network environments:
-
Adaptive Load Distribution
- Weighted Cost Multipathing (WCMP) with 32-way equal-cost path support
- Dynamic interface health scoring using BFD echo mode (300ms intervals)
-
Security Integration
- AES-256 encrypted traffic flow labels for service chaining visibility
- Automated ACL synchronization across vManage 20.7+ controllers
-
Protocol Optimization
- BGP Add-Path extensions for 4-byte ASN environments
- OSPFv3 LSA throttling adjustments to prevent control plane flooding
-
Telemetry Enhancements
- Embedded NetFlow v11 templates for application-aware traffic analysis
- Streaming telemetry support at 10-second intervals via gRPC
Compatibility and Requirements
