Audience
Preface
This guide is for the networking professional managing the Cisco Catalyst Blade Switch 3020 for HP,
hereafter referred to as the switch module. Before using this guide, you should have experience working
with the Cisco IOS software and be familiar with the concepts and terminology of Ethernet and local
area networking.
Purpose
This guide provides the information that you need to configure Cisco IOS software features on your
switch. The Cisco Catalyst Blade Switch 3020 for HPsoftware provides enterprise-class intelligent
services such as access control lists (ACLs) and quality of service (QoS) features.
This guide provides procedures for using the commands that have been created or changed for use with
the Cisco Catalyst Blade Switch3020 for HP. It does not provide detailed information about these
commands. For detailed information about these commands, see the Cisco Catalyst Blade Switch 3020
for HP Command Reference for this release. For information about the standard Cisco IOS Release 12.2
commands, see the Cisco IOS documentation set available from the Cisco.com home page at Technical
Support & Documentation > Cisco IOS Software.
This guide does not provide detailed information on the graphical user interface (GUI) for the embedded
device manager that you can use to manage the switch. However, the concepts in this guide are applicable
to the GUI user. For information about the device manager, see the switch online help.
This guide does not describe system messages you might encounter or how to install your switch. For
more information, see the Cisco Catalyst Blade Switch 3020 for HP System Message Guide for this
release and the Cisco Catalyst Blade Switch 3020 for HP Hardware Installation Guide.
For documentation updates, see the release notes for this release.
