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
t describes how to use the command line interface (CLI) to configure,
I
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
1-2
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 >

Conventions
Command Prompts
In the default configuration, your switch displays a CLI prompt similar to the
following example:
ProCurve 8212zl#
To simplify recognition, this guide uses ProCurve to represent command
prompts for all switch models. For example:
ProCurve#
(You can use the hostname command to change the text in the CLI prompt.)
Screen Simulations
Displayed Text. Figures containing simulated screen text and command
output look like this:
Figure 1-1. Example of a Figure Showing a Simulated Screen
In some cases, brief command-output sequences appear without figure identification. For example:
ProCurve(config)# clear public-key
ProCurve(config)# show ip client-public-key
show_client_public_key: cannot stat keyfile
Configuration and Operation Examples
Unless otherwise noted, examples using a particular switch model apply to all
switch models covered by this guide.
Keys
Simulations of actual keys use a bold, sans-serif typeface with square brackets.
For example, the Tab key appears as
[Tab] and the “Y” key appears as [Y].

Migrating to IPv6
To successfully migrate to IPv6 involves maintaining compatibility with the
large installed base of IPv4 hosts and routers for the immediate future. To
achieve this purpose, software release K.13.01 supports dual-stack (IPv4/IPv6)
operation and connectons to IPv6-aware routers for routing IPv6 traffic
between VLANs and across IPv4 networks.
Note Software release K.13.01 supports traffic connections with IPv6-aware
routers, but does not support IPv6 routing operation in the switches covered
by this guide.
Beginning with software release K.13.01, the switches covered by this guide
support the following IPv6 protocol operations:
■ receiving IPv6 traffic addressed to the switch
■ transmitting IPv6 traffic originating on the switch
■ switching IPv6 traffic between IPv6 devices connected to the switch on
the same VLAN
■ concurrent (dual-stack) operation with IPv4 traffic and devices on the
same VLAN
■ using a connection to an external, IPv6-configured router, forward IPv6
traffic intended for devices on other VLANs and for traffic that must
traverse an IPv4 network to reach an IPv6 destination

Introduction to IPv6
Migrating to IPv6
IPv6 Propagation
IPv6 is currently in the early stages of deployment worldwide, involving a
phased-in migration led by the application of basic IPv6 functionality. In these
applications, IPv6 traffic is switched among IPv6-capable devices on a given
LAN, and routed between LANs using IPv6-capable routers. Using the IPv6
features in this software release, the switch can operate in an IPv6 network,
be managed using an IPv6 management station, and interact with DHCPv6 and
IPv6-enabled DNS servers in the same network or accessible through a
connection to an IPv6 router.
Dual-Stack Operation
Since most initial IPv6 deployments are in networks having a mixture of IPv6
and IPv4 hosts software release K.13.01 supports dual- stack IPv4/IPv6 operation. This enables the switch to communicate individually with IPv4 and IPv6
devices with their respective protocols. Thus, IPv4 and IPv6 traffic is
supported simultaneously on the same VLAN interface. This means that both
IPv4 and IPv6 devices can operate at the same time on a given VLAN.
Note Software release K.13.01 does not include gateways for translation between
IPv6 and IPv4 traffic. While IPv4 and IPv6 traffic coexists on the same VLAN,
the individual IPv4 and IPv6 devices ignore each other's traffic.

To forward IPv6 traffic from the switch to an IPv6-capable device on a different
VLAN, a link to an external IPv6-capable router is needed. Also, IPv6 traffic
movement from the switch over IPv4 paths requires routers capable of IPv6
over IPv4 tunneling.
