Abstract
Techniques described use Generic Framing Procedure (GFP) to transport data across an optical transport network between near and far Fiber Channel (FC) or Fiber Connectivity (FICON) local area optical networks. Each FC/FICON edge node (FCE) on an edge of the optical transport network has multiple modes for processing FC/FICON frames transported across the optical transport network. The techniques include receiving, at a near FCE from a far FCE, a GFP control plane message that includes a mode field that holds data that indicates a far mode, wherein the far mode is used at the far FCE. It is determined whether a near mode used by the near FCE matches the far mode based on the mode field. If it is determined that they do not match, then an alert is caused. These techniques allow software to utilize existing GFP chips in FCE that use optional processing, such as distance extension.
