Embodiment 1

[0048] In this embodiment, a loopback detection method is provided, figure 2 is a flowchart of a loopback detection method according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:

[0049] Step S202, receiving a loopback detection message, wherein the loopback detection message carries a destination media access control MAC address, and the destination MAC address is a multicast MAC address;

[0050] Step S204, judging whether to terminate the loopback detection message according to the destination MAC address;

[0051] Step S206, if the judgment result is yes, terminate the loopback detection message.

[0052] Through the above steps, a loopback detection message is received, wherein the loopback detection message carries a purpose media access control MAC address, and the purpose MAC address is a multicast MAC address; whether to terminate the loopback detection message is judged according to the purpose MA...

Abstract

The present invention provides a loopback detection method and device, wherein the method includes: receiving a loopback detection message, wherein the loopback detection message carries a purpose media access control MAC address, and the purpose MAC address is a multicast MAC address; judge whether to terminate the loopback detection message according to the destination MAC address; if the judgment result is yes, terminate the loopback detection message. By adopting the above technical solution, the problem that the MIP cannot terminate the loopback detection message in the multicast mode is solved, and the loopback detection message in the multicast mode is terminated by the MIP.

Description

technical field [0001] The present invention relates to the communication field, in particular to a loopback detection method and device. Background technique [0002] In the current Ethernet, the standard organization Institute of Electrical and Electronics Engineers (IEEE) has formulated a set of working mechanisms for Ethernet Operation, Administration and Maintenance (OAM). , and was officially released as the 802.1ag standard in 2007. [0003] The IEEE 802.1ag standard defines the logical entity of the OAM function in Ethernet, including the Maintenance End Point (MEP) located at both ends of the Ethernet transmission path, and the Maintenance Intermediate Point (Maintenance Intermediate Point) located in the middle of the Ethernet transmission path. , referred to as MIP). Wherein, the maintenance endpoint and the maintenance intermediate point are collectively referred to as a maintenance point (Maintenance Point, MP for short). The maintenance point in the Ethernet...
