Switch Automated Connection Verification via VLAN and IP Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the correct connection of a network cable between a server and a switch in large-scale systems, such as cloud computing, are inefficient and require manual intervention, particularly in systems with numerous servers and switches.
Innovation Solution
An automated method and device that analyze the Virtual Local Area Network (VLAN) identification information and Internet Protocol (IP) address information transmitted through the network connection to determine if the cable is correctly plugged in, using indicators to signal correct or incorrect connections and minimizing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual ping operations are used to detect network cable connections, then connection verification can be performed, but productivity is low and manual intervention is required
Solution Approach 1:
The system performs self-identification by automatically comparing the VLAN ID and IP address received from the server with pre-configured expected values. The switch autonomously determines whether the network cable is correctly connected without requiring manual ping operations or operator intervention, thereby resolving the contradiction between verification reliability and detection efficiency.
2Productivity
If automated identification methods are implemented, then productivity improves, but device complexity increases
Solution Approach 1:
The switch leverages its existing multi-functional capabilities by integrating connection verification into its standard operating procedures. Instead of adding dedicated verification hardware, the switch uses its existing processing units to simultaneously handle data forwarding and connection identification, thus improving productivity without significantly increasing device complexity.
Solution Approach 2:
The system implements a feedback mechanism where the switch receives VLAN ID and IP address information from the server, compares these values with pre-configured expected values, and automatically determines connection correctness. This closed-loop feedback process enables automated identification while maintaining relatively simple system architecture by reusing existing communication channels.
3Measurement precision
If extensive manual checking is performed in large-scale systems, then connection accuracy can be verified, but time consumption increases
Solution Approach 1:
The system performs preliminary action by pre-configuring the expected VLAN ID and IP address values in the switch before actual connection occurs. When the server connects, the switch immediately compares the received values against these pre-prepared references, enabling rapid and accurate connection verification without requiring time-consuming manual checking or complex real-time analysis.

AI summary
An information processing method and a switch are described, in which the method includes the steps of acquiring a first information transmitted by the server through the first connection; deciding whether a first parameter in the first information matches a first predetermined parameter, the first parameter including at least Virtual Local Area Network (VLAN) identification information and Internet Protocol (IP) address information corresponding to a network port into which the first connection line is plugged on the server; determining the first connection line connected at the switch is in a wrong connection when it is decided that the first parameter does not match the first predetermined parameter. The recognition whether a connection of a network cable plugged in a network port of the server and the port of the switch are correct may be realized automatically.
