What’s new in this document

This manual applies to FCIP support in Fabric OS version 6.4.0 and later releases. New features

include support for IPSec, support for VLAN and DSCP tagging, and support for VEX ports on the

FX8-24 blade.

Document conventions

This section describes text formatting conventions and important notice formats used in this

document.

Text formatting

The narrative-text formatting conventions that are used 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 command 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.
