Embodiment Construction

[0060] The embodiment of the present invention firstly introduces the slow protocol. According to the research on the slow protocol defined by IEEE 802.3, the characteristics of the slow protocol message and the transmission characteristics of the slow protocol are defined in the ANNEX of the Institute of Electrical and Electronics Engineers (English: Institute of Electrical and Electronics Engineers, IEEE) 802.3. The characteristics of the message include: the destination Media Access Control (English: Media Access Control, referred to as: MAC) address of the slow protocol message uses the slow protocol multicast address (English: Slow_Protocols_Multicast address), and the value of the slow protocol multicast address is 01 -80-c2-00-00-02; the value of the type field of the slow protocol packet is 8809. Wherein, the value of the type field of the protocol packet is used to indicate that the protocol packet is a slow protocol packet. Therefore, the link layer protocols corres...

Abstract

An embodiment of the present invention provides a slow protocol packet processing method and a related device, the method comprising: a network device receiving a first slow protocol packet, the first slow protocol packet carrying the first slow protocol packet The device information of the sending end device; the network device determines that the negotiation process has been completed between the network device and the sending end device according to the port information of the port of the network device that receives the first slow protocol message, According to the device information of the sender device carried in the first slow protocol packet, search whether the device information library stored by the network device during the negotiation process includes the device information of the sender device; in response to the The device information database includes the result of the device information of the sending end device, and the network device identifies the first slow protocol packet as a legal packet. It can be seen that the embodiment of the present invention provides a verification method for slow protocol packets, thereby improving security.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a slow protocol message processing method and a related device. Background technique [0002] In the field of communication technology, the protocol message of the slow protocol (English: Slow Protocol) has the following characteristics: the destination media access control (English: Media Access Control, referred to as: MAC) address of the protocol message uses the slow protocol multicast address (English: : Slow_Protocols_Multicast address), the value of the slow protocol multicast address is 01-80-c2-00-00-02; the value of the type field of the protocol packet is 8809. [0003] At present, based on the slow protocol, the local device and the peer device usually establish a communication link during the negotiation process, and in order to maintain the communication link, the local device and the peer device are in the working process after...
