Solution Overview

Problem

The administration and management of stacking trunks in complex network switch systems are cumbersome, time-consuming, and error-prone due to the need for manual configuration and the difficulty in identifying incorrect physical connections.

Innovation Solution

The system automatically discovers the physical topology and configures stacking trunks, detects and reports erroneous connections, and corrects existing trunk configurations based on the discovered topology, eliminating the need for manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual configuration commands are entered at each switch to create stacking trunks, then stacking trunk configuration is achieved, but the administration and management becomes cumbersome, time-consuming, and error-prone

Engineering Contradiction:
Improvestacking trunk configurationVSAvoidconfiguration time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs self-configuration by automatically detecting physical connections between switches and generating appropriate stacking trunk configurations without requiring manual intervention. The switch examines received packets, identifies connected neighbors, and autonomously creates trunk configurations that match the physical topology.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary detection of physical connections and automatically generates configuration commands before manual configuration can occur. By pre-determining the appropriate trunk configurations based on detected topology, the system eliminates the need for time-consuming manual configuration steps.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If manual inspection of cabling at each unit is performed to find incorrect connections, then connection errors are detected, but the process becomes very difficult and time-consuming in large/complex topology

Engineering Contradiction:
Improveconnection error detectionVSAvoidinspection time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system uses feedback from received packets to automatically verify and correct configuration accuracy. By continuously monitoring incoming packets and comparing physical connections with configured trunks, the system can detect and report mismatches between actual cable connections and configuration data, enabling precise error detection without manual inspection.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical inspection of physical cabling with automated electronic detection using packet analysis. The switch electronically examines incoming packets to identify connected neighbors and compares this information with the configured trunk topology, substituting time-consuming physical cable tracing with rapid electronic verification.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If automatic discovery and configuration is implemented, then the creation and management of stacking trunks is simplified, but the system complexity increases

Engineering Contradiction:
Improvetrunk managementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The switch performs self-configuration by automatically detecting physical connections and generating appropriate trunk configurations without external intervention. This self-service capability simplifies operations for users while the automated processes handle the complexity internally.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The switch integrates multiple functions into a single automated process: physical topology discovery, connection verification, configuration generation, and error detection. By combining these functions, the system manages complexity internally while presenting a simplified interface to users.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Techniques for simplifying stacking trunk creation and management are provided. In one embodiment, a switch in a stacking system can receive first and second control packets from one or more other switches in the stacking system, where the first and second control packets are received on first and second stacking ports of the switch respectively. The switch can then determine, based on the first and second control packets, whether the first and second stacking ports can be configured as a single stacking trunk.
