The following terms are used in this manual to describe Access Gateway mode and its components.
Access
Gateway
(AG)
Fabric OS mode for switches that reduces storage area network (SAN)
deployment complexity by leveraging N_Port ID Virtualization (NPIV).
Device Any host or target device with a distinct WWN. Devices may be physical or
virtual.
D_Port A port configured as a diagnostic port on an AG switch, connected fabric
switch, or connected cascaded AG switch to run diagnostic tests between the
ports and test the link.
E_Port An interswitch link (ISL) port. A switch port that connects switches together to
form a fabric.
Edge
switch
A fabric switch that connects host, storage, or other devices, such as Brocade
Access Gateway, to the fabric.
F_Port A fabric port. A switch port that connects a host, host bus adapter (HBA), or
storage device to the SAN. On Brocade Access Gateway, the F_Port connects
to a host or a target.
Mapping In Access Gateway, mapping defines the routes between devices or F_Ports
to the fabric facing ports (N_Ports).
N_Port A node port. A Fibre Channel host or storage port in a fabric or point-to-point
connection. On Brocade Access Gateway, the N_Port connects to the Edge
switch.
NPIV N_Port ID Virtualization. This is a Fibre Channel facility allowing multiple
N_Port IDs to share a single physical N_Port. This allows multiple Fibre
Channel initiators to occupy a single physical port, easing hardware
requirements in storage area network design, especially for virtual SANs.
