Device and method for extending VLAN ACCESS port functions

Abstract

The invention discloses a device and method for extending the function of a VLAN ACCESS port. The device includes a switch body provided with an ACCESS port. The uplink port of the switch body is connected to an uplink device through a hub, and the outgoing direction of the uplink port is respectively connected to all downlink ports. The downlink ports are respectively connected to downlink devices, and the uplink ports and downlink ports are respectively configured with different VLAN IDs. The device can complete the functions of the access port and the hybrid port of the traditional switch through an access port, so that the switch only needs to support the access port mode to complete the data forwarding of the second layer or other business layers of the traditional switch, which can be greatly improved. It is convenient for customers to configure and use the switch, making the use of the interface mode more concise and clear. At the same time, it also greatly saves the resources of the physical interface of the switch.

Description

technical field [0001] The invention relates to a device and method for extending the function of a VLAN ACCESS port, and belongs to the technical field of network switches. Background technique [0002] With the rapid development of network communication technology, its application field gradually penetrates into all aspects of social life, and affects and changes people's production and life style. A switch is a network device used for electrical signal forwarding. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switches are Ethernet switches. Other common ones are telephone voice switches, fiber optic switches, etc. The main functions of the switch include physical addressing, network topology, error checking, frame sequence, and flow control. At present, the switch also has some new functions, such as support for VLAN (virtual local area network), support for link aggregation, and some even have the...

Problems solved by technology

An access port can only forward data packets of one VLAN ID. If you want to forward data packets with multiple VLAN IDs, you need to use multiple physical ports of the switch; although a hybrid port can forward data packets with multiple VLAN IDs However, the working mode of the hybrid port is similar to the working mode of the trunk and access ports, and it is easy to confuse people when using it; and too many port mode configuration options make it very inconvenient for users to use
