The present disclosure relates to systems and methods for configuring a communication device based, at least in part, on a small form-factor pluggable (SFP) transceiver. An SFP transceiver may be utilized in connection with a communication device that transmits data according to a variety of communication protocols. In various embodiments, the configuration may be based upon an SFP configuration value stored in a machine-readable storage medium in the SFP transceiver. In certain embodiments, the SFP configuration value may be an input, together with other values associated with the SFP transceiver and a secret key, to an algorithm for generating a license entitlement key. Certain embodiments may allow for the configuration of a communication device and/or distribution of license entitlement keys in the field.
