• FC Ports are uniquely identified by their WWN
• FC Ports are dynamically assigned an FCID
This slide brings together the logical port types described.
Many switches support auto-configuring ports that automatically configure
themselves for either F_Port, FL_Port or E_Port operation. Such ports are
called G_Ports (Generic Ports) or U_Ports (Universal Ports).
FC Ports are assigned a World Wide Port Name (WWPN) by the manufacturer
that uniquely identifies them in a SAN.
Nodes are also assigned a World Wide Node Name (WWNN).
FC Ports are also dynamically assigned a Fibre Channel ID (FC_ID) which is
used for routing frames across the fabric.
