Access Gateway Administrator’s Guide 1
Publication Number: 53-1000430-01
About This Document
This document is a procedural guide to help SAN administrators configure and manage Brocade Access
Gateway.
Supported hardware and software
This document is specific to Fabric OS v5.2.1 or higher running on the Brocade SilkWorm 4012, 4016,
4020, and 4024 embedded switches.
When procedures or parts of procedures documented here apply to some switches but not to others, this
guide identifies which switches are supported and which are not.
This document sometimes mentions other Fabric OS releases to highlight the changes in the latest
release or to point out interoperability issues with other SilkWorm models. It also specifies when
procedures or steps of procedures apply only to specific SilkWorm models.
Although many different software and hardware configurations are tested and supported by Brocade
Communications Systems, Inc. for this Brocade Fabric OS release, documenting all possible
configurations and scenarios is beyond the scope of this document.
How this document is organized
The document contains the following topics:
•Chapter 1, “Introduction to the Brocade Access Gateway,” describes the Access Gateway
operation.
•Chapter 2, “Configuring Access Gateway,” provides the initial setup procedures and fabric
requirement to deploy an Access Gateway solution.
•Chapter 3, “Disabling Access Gateway Mode,” provides instructions on disabling Access Gateway
mode so that the switch can be used as a fabric switch.
•Chapter 4, “Managing Ports in Access Gateway mode,” provides instructions on changing N_Ports
to F_Ports, mapping F_Ports to N_Ports, and changing failover and failback policies.
The appendices provide the default mappings, compatibility guidelines, and troubleshooting assistance.

Document conventions
This section describes text formatting conventions and important notices formats.
Text formatting
The narrative-text formatting conventions that are used in this document are as follows:
bold text Identifies command names
Identifies the names of user-manipulated GUI elements
Identifies keywords and operands
Identifies text to enter at the GUI or CLI
italic text Provides emphasis
Identifies variables
Identifies paths and Internet addresses
Identifies document titles
code text Identifies CLI output
Identifies syntax examples
For readability, command names in the narrative portions of this guide are presented in mixed
lettercase: for example, switchShow. In actual examples, command lettercase is often all lowercase.
Otherwise, this manual specifically notes those cases in which a command is case sensitive. The
ficonCupSet and ficonCupShow commands are an exception to this convention.
Notes, cautions, and warnings
The following notices appear in this document.
Note
A note provides a tip, emphasizes important information, or provides a reference to related information.
Caution
A caution alerts you to potential damage to hardware, firmware, software, or data.
Warning
A warning alerts you to potential danger to personnel.

Key terms
For definitions of SAN-specific terms, visit the Storage Networking Industry Association online
dictionary at: http://www.snia.org/education/dictionary.
For definitions specific to Brocade and Fibre Channel, see the Brocade Glossary.
The following terms are used in this manual to describe Access Gateway mode and its components.
Access Gateway (AG) Fabric OS mode for embedded switches that reduces SAN (storage area
network) deployment complexity by leveraging NPIV (N_Port ID
virtualization).
Edge switch Fabric switch that connects host, storage, or other devices, such as Brocade
Access Gateway, to the fabric.
NPIV N_Port ID virtualization. Allows a single Fibre Channel port to appear as
multiple, distinct ports providing separate port identification and security
zoning within the fabric for each operating system image as if each operating
system image had its own unique physical port.
E_Port An ISL (InterSwitch link) port. A switch port that connects switches together
to form a fabric.
F_Port A fabric port. A switch port that connects a host, HBA (host bus adaptor), or
storage device to the SAN. On Brocade Access Gateway, the F_Port connects
to a host only.
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.
mapping On Brocade Access Gateway, the configuration of F_Port to N_Port routes.
