Wireshark, by default, will put a NIC into promiscuous mode when opening it for capture.

You can disable this by going to the Capture Interfaces dialog (menu Capture -> Options or Ctrl + K) and unchecking the "Promiscuous" checkbox of the required interfaces.

As Wireshark defaults to promiscuous mode you might also be referring to setting your switch port to such a mode, this is called port mirroring or spanning and you'll have to consult your switch manual for that, Wireshark can't help here.
