Abstract: This application provides a method, device, and system for processing a VXLAN packet. The method includes: obtaining, by a controller, a request message for requesting allocation of a VNI, obtaining the VNI and a VXLAN security policy corresponding to the VNI according to the request message, and delivering the VNI and the VXLAN security policy corresponding to the VNI to a network device. When encapsulating a VXLAN packet, a network device used as a transmit end applies the corresponding VXLAN security policy according to the VNI to encrypt the VXLAN packet. When decapsulating the VXLAN packet, a network device used as a receive end applies the corresponding VXLAN security policy according to the VNI to decrypt the encrypted VXLAN packet.

Abstract: A packet transmission method includes: receiving, by a forwarding device through a port, a protocol packet from another forwarding device or user equipment; performing, by the forwarding device, virtual extensible local area network VXLAN encapsulation on the protocol packet to generate a first VXLAN packet, where the first VXLAN packet includes the protocol packet and the port information; and sending, by the forwarding device, the first VXLAN packet to the controller.
