Some managed switches work right out of the box like an unmanaged one, some do require some configuration in any case.

On your switch some interfaces/ports are shut down (default on some switches) and seem to be configured as UNI (UNI and ENI talk to NNI ports only). To enable them and make them switching universally:

    enable
    config
    interface GigabitEthernet0/1-2
      no shutdown
      port-type nni
    exit
    write mem
