An interfabric link between two separate Fiber Channel fabrics so that devices in one fabric can communicate with devices in another fabric without requiring the merger of the two fabrics. The interfabric switch performs a conversion or a translation of device addresses in each fabric so that they are accessible to the other fabric. In a first embodiment the external ports of the interfabric switch are configured as E_ports. A series of internal ports in each interfabric switch are joined together forming a series of virtual or logical switches. In a second embodiment the external ports are configured as NL_ports and the connections between the virtual switches are E_ports. The virtual switches in the interfabric switch match domains with their external counterparts so that the virtual switches effectively form their own fabric.
