Presented are efficient systems and methods for automatically detecting and configuring network connections in Fibre Channel (FC) and similar networks. In various embodiments, this is accomplished by using an I/O module (IOM)'s fabric login (FLOGI) response or FLOGI request to identify the type of an uplink interface as either FC Gateway or FC Direct Attach, determining whether server interfaces coupled to the TOM support FCoE, and then, automatically configuring server interfaces based on the identified type of uplink interface.
