Key Access Gateway Terms
For definitions of the SAN-specific terms, visit the Storage Networking Industry Association (SNIA) online dictionary at:
http://www.snia.org/education/dictionary
The following terms are used in this manual to describe Brocade Access Gateway mode and its components.
Access Gateway (AG) A Fabric OS mode for switches that reduces storage area network (SAN) deployment complexity by
leveraging N_Port ID Virtualization (NPIV).
Advanced Device
Security (ADS) policy
A security policy that restricts access to the fabric at the AG level to a set of authorized devices.
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.
edge switch A fabric switch that connects host, storage, or other devices, such as switch running in Brocade Access
Gateway mode, to the fabric.

E_Port An inter-switch link (ISL) port. A switch port that connects switches together to form a fabric.
fabric system A fabric system consists of interconnected nodes that look like a single logical unit when viewed
collectively. A fabric system refers to a consolidated high-performance network system that consists of
coupled storage devices, networking devices, and parallel processing high-bandwidth interconnects such
as 8Gb/s, 10Gb/s, 16Gb/s, or 32Gb/s Fibre Channel ports.
FCoE Fibre Channel over Ethernet (FCoE) refers to a network technology that encapsulates Fibre Channel
frames over Ethernet networks. This allows Fibre Channel to use 10-Gigabit Ethernet or higher-speed
networks while preserving the Fibre Channel protocol.
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. An N_Port presents the AG-connected host or storage device to the fabric. On a Brocade
Access Gateway, the N_Port connects to the edge switch.
NPIV N_Port ID Virtualization. NPIV is a Fibre Channel facility that allows multiple F_Port IDs to share a single
physical N_Port. Multiple F_Ports can be mapped to a single N_Port. This allows multiple Fibre Channel
initiators to occupy a single physical port, easing hardware requirements in SAN design, especially for
virtual SANs.
Port Grouping
(PG) policy
The Port Grouping (PG) policy is used to partition the fabric, host, or target ports within an AG-enabled
module into independently operated groups.

management tool (MyCases) has been replaced with the Fibre
Channel Networking case management tool.
•DocSafe: You can download software and documentation.
•Other Resources: Licensing Portal (top), SAN Health (top and
bottom), Communities (top), Education (top).
Required for Severity 1 (critical) issues:
Please call Fibre Channel Networking Global Support at one of
the numbers listed at https://www.broadcom.com/support/fibre-
channel-networking/.
If you purchased Brocade product support from a Broadcom OEM/solution provider, contact your OEM/solution provider
for all your product support needs.
•OEM/solution providers are trained and certified by Broadcom to support Brocade products.
