Mac Ping initiation method and system

Abstract

The invention relates to a method for initializing Mac Ping and relative system, wherein it comprises that: network device via report in one virtual local network VLAN uses two-layer channel to initialize Mac Ping; the target network device receiving the report builds respond report to be transmitted or broadcast; the network device uses received time mark in respond report to confirm the network device. The invention simplifies the setting of Mac Ping and provides Mac Ping function.

Description

technical field [0001] The invention relates to network fault management technology, in particular to a method and system for initiating Mac Ping. Background technique [0002] The maintenance domain MD (Maintenance Domain) is the network or a certain part of the network involved in the 802.1ag fault management function. It is defined by a series of domain service access points DSAP (Domain Service Access Point). distinguish. Among them, the domain service access point DSAP is the boundary point of the maintenance domain (such as a certain port of the bridge device), which provides connectivity services to the outside of the domain. There may also be an intermediate service access point ISAP (Intermediate Service Access Point) inside the maintenance domain. It is an intermediate node from one DSAP to another DSAP. [0003] like figure 1 As shown, an example of a maintenance domain is given, in which there are 5 bridge devices, and the area (gray part) covered by 6 DSAPs (...

AI Technical Summary

Problems solved by technology

[0011] The existing Mac Ping function based on IEEE 802.1AG limits the use of Mac Ping by users

[0012] For a Layer 2 network operator, maintenance personnel need to initiate MacPing from one device to another device to confirm whether there is a fault between the two or check the current network status to understand the packet loss rate and delay , delay jitter and other parameters, it needs to configure the MD, MA, MEP, MIP and other information defined by the IEEE 802.1AG protocol on each device, which is relatively complicated and inconvenient to use

[0013] Moreover, when configuring the above-mentioned various management information, the user is very likely to misconfigure the situation. As a result, the connectivity between the devices is good, but the situation is caused by the configuration.
