Fibre Channel frame encapsulation occurs on the sending port and the reconstruction of Fibre Channel
frames occurs on the receiving port. This encapsulation and reconstruction is transparent to the initiator
and target.
This chapter uses the terms “local” and “remote” this way: the local switch is the switch that initiates
the FCIP connection request, and the remote switch is the switch that listens for FCIP connection
requests.
Figure 7-1 illustrates a portion of a Fibre Channel network using FCIP. The FCIP interswitch link (ISL)
shows all VE_Ports connected through the IP network that joins two SANs (Data Center FC and Office
FC) into parts of a larger SAN.
Admin Domain considerations: You can configure FCIP and GbE ports configuration only when the
current Admin Domain owns the switch. GbE ports, like FC E_Ports, are visible in all Admin Domains.
Unlike FC E_Ports, they cannot be assigned to any domain in particular, but are configurable wherever
the switch is owned.
For additional information about the FCIP Tunneling Service, see the Fabric OS Administrator’s Guide.
