Example Embodiment

[0029] In order to solve the problems existing in the prior art, the present invention provides a method and device for keeping the IP address unchanged. By pre-configuring a fixed IP address for the user on the authentication server, the switch can obtain the authentication after the user passes the authentication. A fixed IP address is pre-configured on the server, and the IP address is sent to the user's host, so as to ensure that the IP address remains unchanged when the user's physical location changes. Therefore, it can satisfy the application management of the administrator's real-name monitoring of the user's IP address and IP backtracking, thereby improving network security.

[0030] Please refer to figure 1 , is a processing flowchart of a method for keeping an IP address unchanged in an exemplary embodiment of the present invention, and the method is applied to a switch in a VXLAN (virtualextensibleLocalAreaNetwork, virtual extensible local area network) network, be...

Abstract

The present invention provides a method and device for remaining an IP address unchanged. The method is applied to a switch in a VXLAN networking. The method comprises: when the authentication a user host is passed through on an authentication server, the switch receives the authentication result issued by the authentication server, and the authentication result includes a user IP address and the VLAN information distributed by the authentication server in advance according to the authentication information; the switch stores the IP address and the VLAN information corresponding to the user host; and when the switch captures a DHCP request sent by the user host, the IP address and the VLAN information corresponding to the user host are sent to the user host. Therefore, the method and device for remaining an IP address unchanged are able to remain an IP address unchanged when a physical location is changed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for keeping an IP address unchanged. Background technique [0002] With the development of virtualization technology, it can help many large enterprise users get rid of the geographical restrictions of the office. The administrators in the company's network hope that when the user moves or changes the office location, his IP (Internet Protocol, the protocol for interconnection between networks) address can be kept unchanged, so as to monitor the real name of the user's IP address, And application management such as IP backtracking. [0003] In the prior art, authentication information such as user names and passwords are usually recorded on the authentication server. When a user authenticates to access the Internet from the access switch, he must first pass the user identity authentication of the authentication server. After the authentication is pass...
