Switching with transparent and non-transparent ports
First Claim
1. A switch with transparent and non-transparent physical interfaces comprising a first physical interface for interfacing to a first device having a first address in a first shared address domain a second physical interface for interfacing to a second device having a second address in the first shared address domain a third physical interface for interfacing to a third device having a third address in a second address domain, wherein the second address domain is isolated from the first address domain logic for switching data units between the first physical interface, the second physical interface and the third physical interface using mapped address I/O and masking the second address domain.

8. A process for switching data units, the method comprising
providing a switch having transparent and non-transparent physical interfaces associating the transparent physical interfaces with a shared address domain associating the non-transparent physical interfaces with non-shared address domains obtaining translation offsets for the non-shared address domains transferring data units between the transparent physical interfaces, between the transparent and non-transparent physical interfaces, and between the non-transparent physical interfaces.
