Introduction
Introduction
This guide is intended for use with the following switches:
■ProCurve Switch 8200zl series
■ProCurve Switch 5400zl series
■ProCurve Switch 3500yl and 6200yl series
■ProCurve Switch 2900 series
It describes how to use the command line interface (CLI) to configure,
manage, monitor, and troubleshoot switch operation. For an overview of
other product documentation for the above switches, refer to “Product Doc-
umentation” on page ix. You can download documentation from the ProCurve
Networking web site, www.procurve.com.
Conventions
This guide uses the following conventions for command syntax and displayed
information.
Command Syntax Statements
Syntax: ip < default-gateway < ip-addr >> | routing >
Syntax: show interfaces [port-list ]
■Vertical bars ( | ) separate alternative, mutually exclusive elements.
■Square brackets ( [ ] ) indicate optional elements.
■Braces ( < > ) enclose required elements.
■Braces within square brackets ( [ < > ] ) indicate a required element within
an optional choice.
■Boldface indicates use of a CLI command, part of a CLI command syntax,
or other displayed element in general text. For example:
“Use the copy tftp command to download the key from a TFTP server.”
■Italics indicate variables for which you must supply a value when execut-
ing the command. For example, in this command syntax, you must provide
one or more port numbers:
Syntax: telnet < ipv6-address >
