Abstract

Official abstract text for this publication.

Embodiments of the invention relate to virtual link aggregation. One embodiment includes forming one or more virtual links using physical links connecting a first networking element, a second networking element and a third networking element. A first trigger status indication is used for blocking network traffic for avoiding traffic loops occurring over the one or more virtual links.

First claim

Opening claim text (preview).

What is claimed is: 1. A virtual aggregation link system comprising: a primary aggregation switch; a secondary aggregation switch coupled to the primary aggregation switch with a first link that comprises an inter-switch link; a first access switch coupled to the primary aggregation switch with a second link and the secondary aggregation switch with a third link, the first access switch establishing a first virtual link with each one of the primary aggregation switch and the s…
