Abstract
Official abstract text for this publication.
Techniques are provided for detecting failure of switching elements of a distributed switch configured to forward Fiber Channel over Ethernet (FCoE) frames. Periodic discovery advertisement messages, which include a fabric name fieldm, are transmitted between a controlling Fiber Channel Forwarder (cFCF) and a FCoE data forwarder (FDF). The cFCF determines a FDF has failed out of the switch fabric based on a reserved value in the fabric name field of a received discovery advertisement message, such as a zero or null value, and de-instantiates virtual links with that FDF.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer program product for managing a distributed Fibre Channel over Ethernet (FCoE) fabric configured to encapsulate Fibre Channel frames in Ethernet frames, the computer program product comprising: a non-transitory computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code comprising: computer-readable program code, executable by a processor, configured to instantiate a first switch l…
