Method and equipment for automatically distributing/acquiring virtual local area network configuration information

Abstract

The invention discloses a method for automatically distributing virtual local area network configuration information in a wireless local area network. The method comprises the following steps of: receiving an inter-access point protocol (IAPP) registration request message from access point equipment; verifying the validity of the access point equipment; and when the access point equipment is proved valid through verification, providing the virtual local area network configuration information for the access point equipment by using an IAPP protocol. Through the method, the virtual local area network configuration information can be automatically distributed to the access point equipment, and is distributed at the initialization stage of the access point equipment, so that the problem of unavailable distribution of the virtual local area network configuration information by an authentication server due to quick switching of a wireless working station in the prior art is solved. The invention also discloses a relevant authentication server, a method for acquiring the virtual local area network configuration information from the access point equipment in the wireless local area network and relevant access point equipment.

Description

technical field [0001] The present invention relates to a wireless local area network (WLAN), in particular to the technology of configuring a virtual local area network (VLAN) in a wireless local area network. Background technique [0002] With the wide application of wireless local area network technology, the scale of wireless local area network is increasing day by day. part of the operating network. Therefore, how to manage and configure a large-scale wireless LAN has become an important topic. [0003] According to the configuration and use of WLAN, virtual LAN technology is proposed to distinguish various data packets for different purposes. The so-called "virtual local area network" refers to the technology of logically dividing the wireless workstations in the wireless local area network into network segments to realize virtual workgroups. A virtual local area network forms a logical subnet and allows wireless workstations in different physical locations to join ...

Problems solved by technology

In this way, if the wireless workstation associates with the new SSID of the destination access point device, the destination access point device cannot receive the authentication response message embedded with the VLAN flag from the authentication server, and thus cannot assign a virtual LAN to the wireless workstation.
