What is cardIfPortNumber?

This deprecated integer value reports the chassis port number for this interface, unique per port on a given card, and is left unpopulated if not applicable to the card. An admin uses it together with cardIfSlotNumber to pinpoint the exact physical port an interface corresponds to. For example, a cardIfPortNumber of 2 combined with slot 3 identifies port 2 on the card in slot 3.
