Publication number: 20230208836Abstract: This application discloses an access management method, an authenticator, and an authentication server, applied to a scenario in which a terminal device accesses a network. After completing authentication, a terminal device sends a first packet to an authenticator, where the first packet carries a first IPv6 address of the terminal device and a MAC address of the terminal device. When determining that the first IPv6 address is a new IPv6 address, the authenticator sends, to an authentication server, a second packet carrying the first IPv6 address and the MAC address, so as to indicate the authentication server to send a first authorization policy to a policy enforcement point based on the first IPv6 address.Type: ApplicationFiled: February 17, 2023Publication date: June 29, 2023Inventors: Bin HE, Cairen WENG, Yibin XU, Sisheng WANG

Patent number: 10917406Abstract: An access control method, system, and a switch, pertains to the field of network technologies. The access control method includes receiving, by an authentication device, a packet from an access device, where the packet includes a virtual local area network (VLAN) identifier, and authenticating, by the authentication device based on the VLAN identifier and a preconfigured correspondence using an authentication method corresponding to the VLAN identifier, a terminal device sending the packet, where the correspondence includes a mapping from a plurality of VLAN identifiers to at least two authentication methods. Hence, the authentication method of the terminal device is determined based on the VLAN identifier such that different authentication methods may be used for terminal devices in different VLANs. Therefore, an access manner is flexible.Type: GrantFiled: September 12, 2018Date of Patent: February 9, 2021Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventor: Yibin Xu
