This attribute indicates the slot number of the cards to which the
fabric port is currently configured to transmit cells. This
configuration is managed automatically, and cannot be changed by
the operator. By examining this attribute for both of a card's
FabricPort components, it is possible to determine which fabric (if
any) the card uses when it needs to transmits cells to a specific card
in the module.
