Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] To implement the Layer 3 authentication function, the switch needs to judge whether the user has been authenticated based on the source IP address of the packet, and select a route based on the source IP address after the authentication is successful. The topology scenario where the switch acts as a Layer 3 authentication device is as follow...

Abstract

The invention provides a three-layer authentication method and device as well as a three-layer authentication exchanger. The method comprises the following steps: receiving a data message sent by a user at a first port, performing routing list matching according to a source IP (internet protocol) address of the data message, performing matching on the data message in an ACL (access control list) when a matching result is that the data message sent by the user is a to-be-authenticated message, and sending the data message to a CPU (central processing unit) according to the matching result for performing authentication treatment. With the adoption of the technical scheme, the three-layer authentication method and device as well as the three-layer authentication exchanger have the characteristics that the routing list matching is carried out according to the source IP address of the data message in a routing list, the data message is subjected to matching in the ACL when the matching result is that the data message is the to-be-authenticated message, and the data message is transmitted to the CPU for performing authentication treatment, so that problems that an exchanger only can realize a two-layer authentication function and cannot effectively realize three-layer authentication in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a three-layer authentication method, device and three-layer authentication switch. Background technique [0002] In the current network, the switch is mainly used in the distributed authentication of the two-layer network. After the user is authenticated, the source MAC (Media Access Control, Media Access Control) of the user is bound by issuing the ACL (Access Control List, Access Control List) rules. Or source MAC and source IP (Internet Protocol, network protocol) information is used as the judgment of authentication or not. In a large Layer 2 network environment, the switch acts as a gateway device and enables centralized authentication. This solution also uses the MAC address table to determine whether the user's source MAC address exists in the address table to identify whether the user has been authenticated. [0003] In the existing network, Layer 3 authentication ...
