                      Some ports may not be present in the system, in

                      the value of vgRptrGroupPortCapacity.

                      Note:  In practice, this will generally be the
                      number of ports on a module, card, or board, and
                      the port numbers will correspond to numbers marked

                      be repeated as the frame is being received.

                      Note that the value 'someCablesBundled(1)' will
                      work in the vast majority of all installations,
                      regardless of whether or not any cables are
                      physically in a bundle, since packets received
                      from promiscuous and cascaded ports automatically
                      avoid the store and forward.  The main situation
                      in which 'noCablesBundled(2)' is beneficial is
                      when there is a large amount of multicast traffic
