      - F_Port
        
        Fabric Port
        
        a port to which an N_Port attaches
      - E_Port
        
        Expansion port
        
        a port used for inter-switch links (ISLs)
    - - EX_Port
        
        Connect an FC router to a fabric
      - VE_Port
        
        Virtual, used in FCIP fabrics
      - VEX_Port

      - AF_Port
        
        A type of F_Port configured on an AMP used to receive monitored traffic flows
- - - - Well-designed NETWORK of highly intelligent FC switches which provides enterprise-class scalability, performance, manageability and availability
      - Directors
        
        Switches
      - Good LANs doesn´t make a good SAN´s
      - Fabric is a term used to describe a generic switching environment consisting of one or more interconnected switches (domains)
        FID is used to identify each fabric int the SAN
        FID can be from 1 to 128 and must be the same on each switch within the fabric
      - Each switch int the fabric has a domain ID (DID) configured
        
        DID is used do identify each swich within the fabric
        
        DID values can be 1 to 239 and must be different on each switch within the fabric
      - Port ID (PID); used to identify each node in the fabric
        
        Assigned to the node by the domain it is attached to
        
        Area ID The port index number the node is attached to
        
        Node ID a number assigned to identify each node attached to the port
