Problems solved by technology

[0007] The use of this authentication access scheme requires that one port of the access device can only be connected to one terminal device, which will lead to very low network utilization
[0008] 2. The recovery of IP addresses used by this type of terminal equipment in the isolated VLAN is slow, wasting precious resources of IP addresses

Embodiment Construction

[0045] In order to make the present invention clearer and more comprehensible, the following describes the present invention in detail with reference to embodiments and drawings.

[0046] Please refer to figure 1 , In the exemplary embodiment of the present invention, the device and its basic hardware environment are provided for implementing IP address switching when the terminal device performs MAC authentication in the BYOD application scenario, respectively, applied on the Radius server and the access device. Wherein, the device is specifically a logic device that runs on a Radius server and an access device by a software program, and serves as a carrier for running the logic device. The basic hardware architecture of the Radius server and the access device includes a CPU. , Memory, non-volatile storage (such as hard drives), and other hardware. From a logical point of view, the device applied on the Radius server includes a configuration unit, an identification unit and a pr...

Abstract

The invention provides a method and device for IP address switch, and the method and device for IP address switch are used in the process where BYOD scene terminal equipment passes the MAC address certification. According to the method and device for IP address switch, different lease time is issued to equipment with unidentified terminal types and equipment with identified terminal types during the access certification process of the MAC address, and after a terminal type is identified, a Disconnect Message is issued through a COA server to force the terminal equipment to be off-line, and therefore the terminal equipment is triggered to carry out MAC address certification again. The method and device for IP address switch aim to remove the limitation that the accessed equipment must be directly connected with the terminal equipment in the BYOD scene, meanwhile, the problem that IP addresses are recovered slowly in a VLAN in the situation can be solved.

Description

Technical field [0001] The present invention relates to the field of computer communication, and in particular to a method and device for switching the IP address of dumb terminal devices such as printers in a BYOD (Bring Your Own Device) application scenario. Background technique [0002] With the popularity of smart phones and tablets represented by iPhone, iPad, Android, etc., more and more business applications are deployed based on these smart terminals, bringing great convenience to people's lives. BYOD gradually enters people's field of vision, and more and more corporate employees bring their own terminal equipment to work in the office. This method not only facilitates the choice of employees, but also allows companies to save a large amount of fixed investment in office computers. Enterprises allow employees or visitors to bring their own terminal devices into the company network, and the network management needs to intelligently identify the models of these devices an...
