Spanning-tree based loop detection for an ethernet fabric switch

摘要

One embodiment of the present invention provides a switch. The switch includes a local database, a packet processor, a data management module, and a tree construction module. The packet processor extracts spanning tree information associated with a remote switch. The data management module stores the extracted spanning tree information in the local database. The tree construction module assigns an interface state associated with a spanning tree to a local interface based on the extracted spanning tree information.

1. A switch, comprising:
a packet processor operable to extract spanning tree information associated with a remote switch; a data management module operable to store the extracted spanning tree information in a local database; and a tree construction module operable to
assign an interface state associated with a spanning tree to a local interface based on the extracted spanning tree information; andpreclude the local interface from forwarding frames based on the assigned interface state.
