Virtual link aggregations across multiple fabric switches

摘要

One embodiment of the present invention provides a switch. The switch is configurable to be a member of a first fabric switch. The switch includes a link aggregation module. During operation, the link aggregation module marks an ingress-switch field of a frame with a virtual switch identifier. This virtual switch identifier is associated with the switch and a second switch, which is a member of a second fabric switch, and is from a range of identifier associated with the first fabric switch and the second fabric switch. Each of the first fabric switch and the second fabric switch is operable to accommodate a plurality of switches and operate as a single switch.

主权项

1. A switch configured to be a member of a first network of interconnected switches, the switch comprising:
a link aggregation module configured to assign a virtual switch identifier to an ingress-switch field of a first frame, wherein the virtual switch identifier is associated with the switch and a second switch, and wherein the second switch is a member of a second network of interconnected switches; wherein the virtual switch identifier is selected from a range of identifiers allocated for both the first and second networks of interconnected switches;and
wherein each of the first and second networks of interconnected switches is configured to be controlled as a single logical switch.
