Abstract
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.

A virtual aggregation link system comprising:
- a first aggregation switch;
- a second aggregation switch coupled to the first aggregation switch with a first link;
- and
- at least one access switch coupled to the first aggregation switch with a second link and the second aggregation switch with a third link, the first access switch establishes a first virtual link with each one of the first aggregation switch and the second aggregation switch;
- a first traffic management module coupled with the first aggregation switch, wherein the first traffic management module manages networking traffic from the first aggregation switch based at least in part on a first trigger status, and determines the first trigger status based at least in part on establishing of the first virtual link.
A non-transitory computer-useable storage medium for virtual link aggregation, the computer-useable storage medium having a computer-readable program, wherein the program upon being processed on a computer causes the computer to implement:
- coupling a first networking element to a second networking element using a first link;
- coupling the first networking element to a third networking element using a second link;
- coupling the second networking element to the third networking element using a third link;
- establishing a first virtual link between the third networking element and each one of the first networking element and the second networking element;
- managing networking traffic from the first networking element based at least in part on a first trigger status;
- and
- determining the first trigger status based at least in part on establishing of the first virtual link, wherein the first trigger status is set to enabled prior to the establishing of the first virtual link, and the first trigger status is set to disabled after the establishing of the first virtual link.
