A phantom domain is a domain emulated by the Fibre Channel router. The FC router can emulate
two types of phantom domains: front phantom domains and translate phantom domains. For detailed
information about phantom domains, refer to
Phantom domains on page 540.
Proxy devices
An FC router achieves inter-fabric device connectivity by creating proxy devices (hosts and targets) in
attached fabrics that represent real devices in other fabrics.
For example, a host in Fabric 1 can communicate with a target in Fabric 2 as follows:
• A proxy target in Fabric 1 represents the real target in Fabric 2.
• Likewise, a proxy host in Fabric 2 represents the real host in Fabric 1.
The host discovers and sends Fibre Channel frames to the proxy target. The FC router receives these
frames, translates them appropriately, and then delivers them to the destination fabric for delivery to the
target.
The target responds by sending frames to the proxy host. Hosts and targets are exported from the edge
SAN to which they are attached and, correspondingly, imported into the edge SAN reached through
Fibre Channel routing. The following figure illustrates this concept.
