Problems solved by technology

[0003] However, because the switch chip adds a private information header to the Ethernet header of the message according to the private protocol, this will cause the CPU to fail to recognize the message normally because the Ethernet header of the message carries the private information header after receiving the message. Affects the distribution of packets by the CPU

Abstract

The application provides network equipment and a logic device applied to the network equipment. In this application, by adding a logical device to the network device, the logical device will uniformly migrate the private information header originally carried in the Ethernet header of the message from the Ethernet header to the message without affecting the packet except the Ethernet header. The location of the text identification, so as to prevent the identification and distribution of the message from being affected by the private information header carried by the message.

Description

technical field [0001] The present application relates to network communication technology, in particular to network equipment and logic devices applied to network equipment. Background technique [0002] A network device generally consists of a switch chip and a CPU. Among them, when the switch chip sends a message to the CPU, it will first add a private information header to the Ethernet header of the message according to the private protocol, and then send the message carrying the private information header to the CPU, so that the CPU can learn from the private information of the message. Get the message characteristic information in the header. The message feature information may include: the VLAN to which the message belongs, the QoS of the message, the interface information of the peripheral interface that received the message, and the like. [0003] However, because the switch chip adds a private information header to the Ethernet header of the message according to ...
