Problems solved by technology

[0040] For a large-scale network, when the CFD protocol is applied, all devices are generally divided into several maintenance domains, and then the maintenance domain level and other configuration information are configured according to the affiliation of these maintenance domains. This configuration process is cumbersome. If there is a configuration error, t

Embodiment Construction

[0060] The embodiment of the present invention is based on the CFD protocol, replaces the completely manual CFD protocol configuration mechanism, realizes the automatic configuration of the CFD protocol to a certain extent, and solves the problem of cumbersome CFD protocol configuration when the network scale is large.

[0061] Because the CFD protocol itself is only used to solve the problem of link connectivity detection, it is generally used in conjunction with the STP (Shortest Path Tree, shortest path tree) protocol when there is a loop, and the CFD message itself can be blocked by the STP. Therefore, the CFD protocol message flooding problem caused by the deployed network loop does not belong to the solution scope of the embodiment of the present invention.

[0062] The realization goal of the embodiment of the present invention is: on the equipment that constitutes the maintenance domain, by inputting a small amount of (such as 1 to 2) configuration commands, the mainten...

Abstract

The invention discloses a CFD (connectivity fault detection) protocol configuration method and a device thereof. The method comprises the followings steps: when maintenance domains with the same maintenance domain levels are configured for devices in a VLAN (virtual local area network), a primary device and each slave device respectively receive configuration orders of maintenance domain level, and the maintenance domain level of the device is configured according to the orders; the primary device in the VLAN transmits CC (continuity check) massages with the maintenance domain level, each slave device returns to the LT (link trace) massage after receiving the CC massages, wherein an intermediate device which receives the LT massage returns an LTR (link trace reply) massage to a transmitting party device of the LT massage; the primary device configures an outbound maintenance end point on a port which transmits CC massages, ports of slave devices which receive maintenance intermediate points and reply LTR massage exist, the maintenance intermediate point is configured on the port, and maintenance intermediate points are configured on other ports which have the same maintenance domain levels with the maintenance intermediate points; and other slave devices configure outbound maintenance end points on ports which receive CC massages and do not reply the LTR massages. By adopting the method and device provided by the invention, the auto configuration of CFD protocol can be realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a CFD protocol configuration method and a device thereof. Background technique [0002] CFD is the abbreviation of Connectivity Fault Detection (Connectivity Fault Detection), which follows the CFM (Connectivity Fault Management) protocol of IEEE802.1ag and the Y.1731 protocol of ITU-T. It is an end-to-end OAM (Operations, Administration and Maintenance) mechanism based on VLAN (Virtual Local Area Network) on Layer 2 links. Connectivity, confirm faults, and determine where faults occur. [0003] The following is a brief introduction to the concepts involved in the CFD protocol. [0004] Maintenance Domain (MD): It is mainly used to limit the scope of the network that performs connectivity error detection. The maintenance domain uses "maintenance endpoints" to limit the scope of the maintenance domain, and "maintenance domain names" are used to distinguish between ...
