Intended to document interoperability behavior for Fabric elements (i.e., EPort, FPort, FL_Port). The scope of this technical report is to include a wide range of issues such as link initialization, error detection, error recovery, Fabric operation, management capabilities, and zoning. This technical report is intended to serve as an implementation guide, the primary objective of which is to maximize the likelihood of interoperability between conforming implementations. This technical report prohibits or requires some features that are in the referenced ANSI INCITS standards.
