Abstract

The invention provides an EAPS failure detection method. The EAPS failure detection method comprises the following steps: a first detection message is sent through a primary port of a primary node, and the first detection message is received by a secondary port of the primary node after being sequentially forwarded through a plurality of relaying nodes; a second detection message is sent through the secondary port of the primary node, the second detection message is received by the primary port of the primary node after being sequentially forwarded through the relaying nodes, and the second detection message forwarding sequence of the relaying nodes is reversed to the first detection message forwarding sequence of the relaying nodes; the received results of the secondary port and the primary port of the primary node are compared for consistence, and the secondary port of the primary node is blocked through control in case of inconsistence. The invention further provides an EAPS failure detection system implementing the EAPS failure detection method, and an EAPS network employing the system. Through adoption of the EAPS failure detection method and system provided by the invention, unidirectional link failures can be detected, and broadcast storms caused by unidirectional link failures can be further avoided, so that the network is more stable and reliable.

Description

Technical field

[0001] The invention relates to the field of network detection, in particular to an EAPS fault detection method and system and EAPS networking. Background technique

[0002] When the switch is networked, it needs to run for a long time, and it may be unstable or restarted. At this time, the network connection will be disconnected, and the network will split, and it will not form a whole, which will affect users.

[0003] Therefore, there must be one or more backup links in the networking. Under normal circumstances, the backup port on the backup link is in a blocked state and does not forward packets and learns mac entries, so as to avoid loops; when a failure occurs, the backup link restores to the forwarding state and replaces the failed link to work. Avoid network disconnection. This technology is called link redundancy technology.

[0004] There are many link redundancy technologies. EAPS is one of them. It has simple and practical features and can achieve a co...
