Abstract

This invention relates to Ethernet cut-over net virtual LAN cut-over technology including port and 802.1 Q protocol to realize VLAN automatic joining and flexible switch via VLAN ID in virtual LAN tag. This invented method is to set up adaptive VLAN submodule in the equipment soft exchange protocol and function module in which the adaptive VLANN submodule can be distributed into following tasks: interrupting detection task, main process task, ageing process task. Since VLAN ID in tag is applied for automatic joining, cancel ageing, switch in the Ethernet exchange equipment, this method reduces network management manual arrangement need in ordinary VLAN.

Description

technical field

[0001] The invention relates to a virtual local area network access technology of an Ethernet access network. It is a virtual local area network access technology that replaces cumbersome network management configuration with real-time software automatic configuration, has good adaptability to network changes, and does not require complicated network management configuration. Background technique

[0002] Virtual local area network VLAN (Vitrual Local Area Network) is a new technology developed in the field of computer and communication in recent years, and it shows great effect and potential in improving network performance and manageability. But its most attractive advantages are its flexibility and effective control over broadcast domains, and the ability to securely isolate groups of users.

[0003] There are many ways to divide VLANs, and the more commonly used method on Layer 2 devices is based on the mixed method of port port and 802.1Q protocol. The...
