Abstract
A method is provided, including (a) upon a standard small form-factor pluggable (SFP) module being inserted into an SFP jack on a network host device, determining if the SFP module is a legacy device or a smart device, (b) upon determining that the SFP module is a legacy device, receiving a magic code from the SFP module and determining if the magic code is a valid magic code, and (c) upon determining that the SFP module is a smart device, performing a smart authentication process with the SFP module. Associated apparatuses and additional methods are also provided.
