The
CoreBuilder
9000 ATM Enterprise Switch User Guide
provides all the
information that you need to configure and set up the CoreBuilder 9000
ATM Enterprise Switch in ATM networking environments. It also provides
information about how the CoreBuilder 9000 ATM Enterprise Switch
operates in an ATM network.
This guide is intended for the system administrator, network equipment
technician, or network manager who is responsible for installing,
managing, and operating a network that is based on the
CoreBuilder 9000 ATM Enterprise Switch. It assumes a working
knowledge of network operations and familiarity with communications
protocols that are used in networks. No prior knowledge of 3Coms
CoreBuilder networking equipment is necessary to understand the
information in this manual.
If the information in the release notes that are shipped with this product
differs from the information in this guide, follow the instructions in the
release notes.
Most user guides and release notes are available in Adobe Acrobat

Convention Description
Screen displays
This typeface represents information as it appears on the
screen.
Syntax
The word “syntax” means that you must evaluate the syntax
provided and then supply the appropriate values for the
placeholders that appear in angle brackets. Example:
To enable RIPIP, use the following syntax:
SETDefault !<port> -RIPIP CONTrol =
Listen
In this example, you must supply a port number for <port>.
Commands
The word “command” means that you must enter the
command exactly as shown and then press Return or Enter.
Commands appear in bold. Example:
To remove the IP address, enter the following command:
SETDefault !0 -IP NETaddr = 0.0.0.0
The words “enter”
and “type”
When you see the word “enter” in this guide, you must type
something, and then press Return or Enter. Do not press
Return or Enter when an instruction simply says “type.”
Keyboard key names If you must press two or more keys simultaneously, the key
names are linked with a plus sign (+). Example:
Press Ctrl+Alt+Del
