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.
