How this document is organized
This document is a procedural guide to help SAN administrators configure and manage Brocade
Access Gateway.
This preface contains the following components:
•Chapter 1, “Access Gateway Basic Concepts” describes the Brocade Access Gateway and
provides an overview of its key features.
•Chapter 2, “Configuring Ports in Access Gateway mode” describes how to configure ports in
Access Gateway mode.
•Chapter 3, “Managing Policies and Features in Access Gateway Mode” describes how to
enable policies on a switch in Access Gateway mode. It also provides information on how to set
up Failover and Failback, and discusses how Trunking and Adaptive Networking works in AG.
•Chapter 4, “SAN Configuration with Access Gateway” describes how to connect multiple
devices using Access Gateway.
•Appendix A, “Troubleshooting” provides symptoms and troubleshooting tips to resolve issues.
Supported hardware and software
In those instances in which procedures or parts of procedures documented here apply to some
switches but not to others, this guide identifies exactly which switches are supported and which are
not.
Although many different software and hardware configurations are tested and supported by
Brocade Communications Systems, Inc. For Fabric OS v6.4.0, documenting all possible
configurations and scenarios is beyond the scope of this document.

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.
Command syntax conventions
Command syntax in this manual follows these conventions:

ATTENTION
An Attention statement indicates potential damage to hardware or data.
CAUTION
A Caution statement alerts you to situations that can be potentially hazardous to you or cause
damage to hardware, firmware, software, or data.
DANGER
A Danger statement indicates conditions or situations that can be potentially lethal or extremely
hazardous to you. Safety labels are also attached directly to products to warn of these conditions
or situations.

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 SAN (storage area network)
deployment complexity by leveraging NPIV (N_Port ID Virtualization).
Device
Any host or target device with a distinct WWN. Devices may be physical or virtual.

E_Port An ISL (Interswitch link) 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, HBA (host bus adaptor), 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.

Getting technical help
Contact your switch support supplier for hardware, firmware, and software support, including
product repairs and part ordering. To expedite your call, have the following information available:
1. General Information
•Technical Support contract number, if applicable
•Switch model
•Switch operating system version
•Error numbers and messages received
•supportSave command output
•Detailed description of the problem, including the switch or fabric behavior immediately
following the problem, and specific questions
•Description of any troubleshooting steps already performed and the results
•Serial console and Telnet session logs
•Syslog message logs
2. Switch Serial Number
The switch serial number and corresponding bar code are provided on the serial number label,
as shown here.
:
The serial number label is located as follows:
•Brocade 300, 4100, 4900, 5100, 5300, 7500, 7500E, 7800, 8000, VA-40FC, and Brocade
Encryption Switch—On the switch ID pull-out tab located inside the chassis on the port side on
the left
•Brocade 5000—On the switch ID pull-out tab located on the bottom of the port side of the
switch
•Brocade 7600—On the bottom of the chassis
•Brocade 48000—Inside the chassis next to the power supply bays
•Brocade DCX—On the bottom right on the port side of the chassis
•Brocade DCX-4S—On the bottom right on the port side of the chassis, directly above the cable
management comb

3. World Wide Name (WWN)
Use the licenseIdShow command to display the WWN of the chassis.
If you cannot use the licenseIdShow command because the switch is inoperable, you can get
the WWN from the same place as the serial number, except for the Brocade DCX. For the
Brocade DCX, access the numbers on the WWN cards by removing the Brocade logo plate at
the top of the nonport side of the chassis.
