Abstract

The invention relates to a method and opposite terminal apparatus for processing link fault in a virtual switch unit system. The method comprises the following steps of: receiving primary apparatus information which is sent by member apparatuses of the virtual switch unit system; by comparing whether the primary apparatus information which is sent by the member apparatuses is consistent, judging whether a virtual switching link fault occurs in the virtual switch unit system; and if the primary apparatus information which is sent by the member apparatuses is inconsistent, selecting one of the member apparatuses of the virtual switch unit system as a primary apparatus for forwarding, and blocking the ports connected with the member apparatuses of the virtual switch unit system, except the member apparatus selected as the primary apparatus for forwarding. The method has the advantages of solving the problem that the member apparatuses in a recovery mode can not become a new primary apparatus when the primary apparatus has fault after the virtual switching link (VSL) has fault, enhancing the reliability of application of the virtual switch unit (VSU) networking, and effectively improving the abilities of self-repair and fault-resistance of the VSU network.

Description

technical field [0001] The invention relates to a virtual switching unit technology, in particular to a method for dealing with link faults in a virtual switching unit system and an uplink and downlink peer device of the virtual switching unit system. Background technique [0002] The Virtual Switch Unit (VSU) system is to connect two or more devices in the traditional network structure together through the Virtual Switching Link (VSL) to form a single logical entity, which is easy to add network devices bandwidth, improve packet processing capabilities, and provide more stable multi-link backup. [0003] Such as figure 1 As shown, the VSU system at the aggregation layer can be regarded as a device that interacts with the core layer and the access layer. Devices at the access layer are connected to the VSU aggregation layer through Layer 2 aggregation links, and the VSU aggregation layer is connected to core layer devices through Layer 3 aggregation links. Connected to th...
