How this document is organized

.This document is organized to help you find the information that you want as quickly and easily as

possible. It contains the following components:

•Chapter 1, “FCIP Overview” describes FCIP concepts and features.

•Chapter 2, “FCIP on the 7800 Switch and FX8-24 Blade” describes FCIP tunnel and trunking

configuration options for the 7800 switch and FX8-24 blade.

•Chapter 3, “FCIP Management and Troubleshooting” describes FCIP management and

troubleshooting operations.

Supported hardware and software

The following hardware platforms support FCIP as described in this manual:

•Brocade DCX, DCX 8510-8, DCX-4S, and DCX 8510-4 with one or more FX8-24 blades

•Brocade 7800 switch

What’s new in this document

Major new additions or deletions in this document support the following:

•General

-Removed all mention of FR4-18i blade since it is not supported as of this release.

•Preface.

-Removed FR4-18i from “Supported hardware and software” on page ix.

•Chapter 1

-Removed FR4-18i from “FCIP platforms and supported features” on page 1

•Chapter 2

-Added note under “7800 switch license options” on page 7 that FCR is not supported on a

7800 switch that has been partitioned for virtual fabrics. Removed requirement that 7800

upgrade license is required to enable Advanced FICON Acceleration License or CUP.

-Under “Creating an FCIP tunnel” on page 42, modified arguments in “Tunnel Options”

table for the following:

•QoS priority percentages

•Committed rate

•Adaptive rate limiting

•Keep-alive timeout

-Added “Firmware downloads” on page 10 under “FX8-24 blade hardware overview” on

page 8 to include this statement: “If FCIP Fibre Channel traffic is active on Fibre Channel

ports, the traffic will be impacted during a firmware download. “

-Under “Limitations using IPsec over FCIP tunnels” on page 30, modified bullet about IPsec

only being supported on VE group 12-21 on FX8-24 blade to say that “Older versions of the

FX8-24 blade do not support IPsec on group 22-31. For these blades, a RASLOG warning

message will display that blade is not at correct version to support IPsec enabled tunnels

on VEs 22-31.”

-Under “Enabling XISL for VE_Ports” on page 39, added note “Although you can create up

to four logical switches on the Brocade 7800, you cannot use these for XISLs because a

base switch cannot be created.”

-Under “Virtual Fabrics” on page 56, added support for virtual switches and fabrics on

7800 switch. Also added considerations and limitations for virtual fabrics for 7800 switch.

-Under “Limitations of port sharing” on page 57“, added paragraph about effect of

disabling default switch on shared GbE interfaces between the default switch and other

logical switches.

-Removed note that there are no addressing restrictions when using switches or blades

operating with Fabric OS v7.0.0 or later since. This was confusing since IP address limits

are defined for GbE, 10 GbE, and cross ports when in 10 Gbps mode.

-Under “Creating a multicircuit tunnel (example)” on page 50, modified paragraph following

figure titled “FCIP tunnel example with six circuits” describing circuits per tunnel

configured in example and requirements for maximum circuits per port on 7800 switch

and FX8-24 blade.
