Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] In some feasible embodiments of the present invention, the network management server counts the test packets of each group of transmission ports on the test path, and the basis for the counting includes preset access control list ACL rules and traffic policies, so Described traffic policy comprises the classification identification of test message; For each group of transmission ports, judge whether the counting of the test message of two ports in this group of transmission ports is equal according to the counting result of described counting, when judging result is no, Then it is determined that the node to which the group of transmission ports belong or the link connected is faulty.

[0042] figure 1 It is a schematic flowchart of Embodiment 1 of the fau...

Abstract

The embodiment of the invention discloses a failure positioning method and associated equipment. The failure positioning method comprises the following steps of: counting test messages of each group of transmission ports in a test path according to a preset access control list (ACL) rule and a flow policy, wherein the flow policy comprises classification identifiers of the test messages; judging whether the quantity of the test messages of two ports in each group of transmission ports is equal according to a counting result; and if the quantity of the test messages of the two ports in each group of transmission ports is unequal, determining the failures of attribution nodes or connecting links of the group of transmission ports. By the embodiment of the invention, the failures can be quickly, effectively and accurately positioned.

Description

technical field [0001] The invention relates to the communication field, in particular to a fault location method and related equipment. Background technique [0002] At present, for common faults, such as port Down, fiber break, hardware failure, etc., network devices and physical objects on the device will automatically generate alarms and report them through SNMP (Simple Network Management Protocol, Simple Network Management Protocol) Trap (trap) To the network management system, so that the operation and maintenance personnel can directly handle these faults through the monitoring and reporting list of the network management system. For quality degradation faults, such as traffic congestion, high CPU and memory usage of nodes, etc., the network management system establishes performance monitoring instances for services, tunnels, and links at all levels. Collect performance data from network devices regularly, and set thresholds for each performance index based on empiri...
