This reports whether an attempt was made to use this specific port in a way that exceeded its associated software option's licensed port limit (unauthorized) or whether the port has stayed within bounds (authorized). This is the port-level companion to the option-level cdx6500CSISOptionAuth, letting an admin pinpoint exactly which physical port triggered a licensing violation rather than just knowing that some port did. For example, seeing unauthorized on port 30 specifically would tell an admin that configuring port 30 with a licensed feature is what pushed the option over its purchased port count.
