Network Switch VLAN Configuration via Virtual Port Partitioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information handling systems face challenges in efficiently managing and configuring virtual local area networks (VLANs) across virtual switch ports, leading to complexities in network traffic management and VLAN configuration, particularly in environments with multiple virtual machines and network interfaces.
Innovation Solution
The implementation of virtual network interfaces (vNICs) with predefined S-tag values and virtual switch ports within network switches allows for the partitioning of physical network traffic into virtual channels, enabling efficient VLAN configuration and management at the network switch layer, reducing the need for multiple VLAN configurations on servers and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If VLAN configurations are managed on each server individually, then each server can have precise VLAN control, but the complexity of network management increases significantly
Solution Approach 1:
The patent introduces a network switch as an intermediary device that centralizes VLAN management functionality. The switch contains a VLAN configuration database and processing logic that handles VLAN associations for multiple servers, eliminating the need for each server to independently manage VLAN configurations while maintaining precise control
Solution Approach 2:
The network switch is designed to perform multiple functions: it acts as a network forwarding device, a VLAN management server, and a configuration database. This multi-functional design allows centralized management of VLANs across multiple servers through a single device, reducing overall system complexity
2Adaptability or versatility
If multiple VLAN configurations are implemented on each server, then comprehensive network segmentation is achieved, but the administrative burden increases
Solution Approach 1:
The network switch serves as a mediator that handles all VLAN configuration and management operations. Administrators interact with the switch to configure VLANs, and the switch automatically manages the associations between servers and VLANs, eliminating the need for administrators to configure VLANs on each server individually
Solution Approach 2:
The system enables self-service operation where the network switch automatically manages VLAN configurations based on predefined rules and database entries. The switch autonomously handles VLAN association changes, membership management, and configuration updates without requiring manual intervention on each server
3Ease of operation
If VLAN management is centralized at the network switch, then administrative complexity is reduced, but the switch must handle additional processing loads
Solution Approach 1:
The system performs preliminary actions by pre-configuring VLAN parameters, association rules, and membership information in the network switch's database before actual network operations. This pre-processing allows the switch to handle VLAN management requests efficiently during runtime without excessive processing loads

AI summary
A network switch includes a virtual local area network module that determines that a device coupled to a first switch port includes a virtual network interface. The module further identifies a virtual switch port partitioned in the first switch port associated with the virtual network interface and determines that a virtual local area network is associated with the identified virtual switch port.
