Abstract
The disclosed system handles a switch link failure in a switch fabric network. When a node in the switch fabric network detects a failure of a switch link coupled to the node, the system remaps traffic that is directed to a logical port number, which is currently mapped to a primary physical port number associated with the failed switch link, to a secondary physical port number associated with the alternative switch link. This remapping involves performing a lookup in a local mapping table at the node, wherein the local mapping table stores associations between logical port numbers and physical port numbers, wherein for each logical port number, the mapping table includes a primary physical port number and one or more secondary physical port numbers, which are associated with alternative switch links. The system notifies a subnet manager for the switch fabric network about the link failure and the remapping.
