Introduction

Introduction

This Advanced Traffic Management Guide describes how to manage and configure advanced traffic management features on your switch. It supports the following switches:

■ProCurve Series 2610

■ProCurve Series 2610-PWR

For an overview of other product documentation for the above switches, refer to “Product Documentation” on page xiii.

You can download a copy from the ProCurve website, www.procurve.com.

Conventions

This guide uses the following conventions for command syntax and displayed information.

Feature Descriptions by Model

In cases where a software feature is not available in all of the switch models covered by this guide, the section heading specifically indicates which product or product series offer the feature.

For example (the switch model is highlighted here in bold italics):

“Jumbo Packet Support on the Series 2610 Switches”.

Command Syntax Statements

Syntax: aaa port-access authenticator < port-list >

[ control < authorized | auto | unauthorized >]

■Vertical bars ( | ) separate alternative, mutually exclusive elements.

■Square brackets ( [ ] ) indicate optional elements.

■Braces ( < > ) enclose required elements.

1-2

Getting Started

Conventions

■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 executing the command. For example, in this command syntax, < portlist > indicates that you must provide one or more port numbers:

Syntax: aaa port-access authenticator < port-list >

Command Prompts

In the default configuration, your switch displays a prompt as shown below:

ProCurve Switch 2610#

To simplify recognition, this guide uses ProCurve to represent command prompts for all models. For example:

ProCurve#

(You can use the hostname command to change the text in the CLI prompt.)

Screen Simulations

Figures containing simulated screen text and command output look like this:

ProCurve> show version

Image stamp: /sw/code/build/info Nov 2 2007 13 43:14 R.01.XX

ProCurve>

Figure 1-1. Example of a Figure Showing a Simulated Screen

In some cases, brief command-output sequences appear outside of a numbered figure. For example:

ProCurve(config)# ip default-gateway 18.28.152.1/24 ProCurve(config)# vlan 1 ip address 18.28.36.152/24 ProCurve(config)# vlan 1 ip igmp

Port Identity Examples

This guide describes software applicable to both chassis-based and stackable ProCurve switches. Where port identities are needed in an example, this guide uses the chassis-based port identity system, such as “A1”, “B3 - B5”, “C7”, etc. However, unless otherwise noted, such examples apply equally to the stackable switches, which for port identities typically use only numbers, such as “1”, “3-5”, “15”, etc.

Sources for More Information

For additional information about switch operation and features not covered in this guide, consult the following sources:

■ For information on which product manual to consult on a given

	software feature, refer to “Product Documentation” on page xiii.
Note	For the latest version of all ProCurve switch documentation, including
	release notes covering recently added features, visit the ProCurve
	Networking website at www.procurve.com. Click on Technical
	support, and then click on Product manuals.
	■ For information on specific parameters in the menu interface, refer
	to the online help provided in the interface. For example:

■For information on specific features in the Web browser interface, use the online help. For more information, refer to the Management and Configuration Guide for your switch.

■For further information on ProCurve Networking switch technology, visit the ProCurve website at:

Need Only a Quick Start?

IP Addressing

If you just want to give the switch an IP address so that it can communicate on your network, or if you are not using multiple VLANs, ProCurve recommends that you use the Switch Setup screen to quickly configure IP addressing. To do so, do one of the following:

■Enter setup at the CLI Manager level prompt.

ProCurve# setup

■In the Main Menu of the Menu interface, select

8.Run Setup

For more on using the Switch Setup screen, see the Installation and Getting Started Guide you received with the switch.

To Set Up and Install the Switch in Your Network

Important! Use the Installation and Getting Started Guide shipped with your switch for the following:

■Notes, cautions, and warnings related to installing and using the switch and its related modules

■Instructions for physically installing the switch in your network

■Quickly assigning an IP address and subnet mask, setting a Manager password, and (optionally) configuring other basic features.

■Interpreting LED behavior.

For the latest version of the Installation and Getting Started Guide and other documentation for your switch, visit the ProCurve website. (Refer to “Product Documentation” on page xiii of this guide for further details.)

Static Virtual LANs (VLANs)

Overview

Overview

This chapter describes how to configure and use static, port-based VLANs on the switches covered by this manual.

For general information on how to use the switch’s built-in interfaces, refer to these chapters in the Management and Configuration Guide for your switch:

■Chapter 3, “Using the Menu Interface”

■Chapter 4, “Using the Command Line Interface (CLI)”

■Chapter 5, “Using the Web Browser Interface”

■Chapter 6, “Switch Memory and Configuration”

A VLAN is a group of ports designated by the switch as belonging to the same broadcast domain. (That is, all ports carrying traffic for a particular subnet address would normally belong to the same VLAN.)

This chapter describes static VLANs, which are VLANs you manually config­ ure with a name, VLAN ID (VID), and port assignments. (For information on dynamic VLANs, see chapter 3, “GVRP”.)

Using a VLAN, you can group users by logical function instead of physical location. This helps to control bandwidth usage by allowing you to group highbandwidth users on low-traffic segments and to organize users from different LAN segments according to their need for common resources.

By default, 802.1Q VLAN support is enabled for eight VLANS. The table below shows the maximum number of VLANs you can configure on each switch model:

Table 2-1.VLAN Maximums

Switch Model	Maximum Supported VLANs
Series 2610 Switches	Up to 256
Series 2610-PWR Switches	Up to 256

(802.1Q compatibility enables you to assign each switch port to multiple VLANs, if needed, and the port-based nature of the configuration allows interoperation with older switches that require a separate port for each VLAN.)
