Problems solved by technology

[0007] In order to solve the problem that the fault location of the Ethernet link cannot be performed by sending LB / LT messages because the physical address of the node is not known, the embodiment of the present invention proposes a method for obtaining the physical address of the Ethernet node. The method includes :

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0026] When a device needs to locate a fault on a MEP node in the MA through LB / LT packets, the user enters the MEP-ID of the MEP node on the device. If the device does not find the MEP-ID corresponding destination MAC address, the device sends a query message in multicast mode, and parses out the destination MAC address corresponding to the MEP-ID from the query response message, and establishes a mapping relationship between the MEP-ID and the destination MAC address , and set the aging time at the same time. In this way, when fault location is performed through LB / LT messages, as long as the MEP-ID of the destination node is used, the MAC address of the destination node can be obtained by querying the mapping relationship table, thereby realizing the forwarding of LB / LT messages.

Abstract

The invention provides one method to get Ethernet point physical address, which comprises the following steps: sustaining association one point and researching design point physical address; if yes, the sending to other point with design point inf9rmation index message; keeping association other point information to find out its physical address; sending index message point from message and to analyze design point physical address and to establish design point and physical address map relation. The invention also provides one device to get the Ethernet point physical address.

Description

technical field [0001] The invention relates to the field of network management, in particular to a method and a device for obtaining the physical address of an Ethernet node. Background technique [0002] Ethernet technology has been widely used in LAN, MAN, and WAN because of its features such as ease of use, low price, and continuous increase in bandwidth. However, the maintainability, manageability, and operability of traditional Ethernet are relatively weak. With the gradual expansion of the application range of Ethernet, the demand for Ethernet OAM (Operation, Administration and Maintenance) functions is also increasing. It is getting stronger and stronger. Ethernet OAM refers to the operation, management, and maintenance of Ethernet. Its functions can be divided into fault management and performance management: fault management is used for network connectivity detection, similar to BFD (Bidirectional Forwarding Detection-bidirectional forwarding detection), MPLS (Mul...
