Selecting a Management Interface

This chapter describes the following:

■ Management interfaces for the Switch 212M and the Switch 224M

■ Advantages of using each interface

Understanding Management Interfaces

Management interfaces enable you to reconfigure the switch, monitor switch status and performance, and perform troubleshooting tasks.

The Switch 212M and 224M offer the following interfaces:

■ The HP web browser interface --an interface that is built into the switch

and can be accessed using a standard web browser (such as Netscape Navigator or Microsoft Internet Explorer)

■ The switch console--a VT-100/ANSI console interface built into the switch

■ HP TopTools for Hubs & Switches--an easy-to-use, browser-based

network management tool that works with HP proactive networking features that are built into managed HP hubs and switches (included on a CD with the switch)

Selecting a Management

Interface

Each interface consists of a series of management features, accessed either through menu-driven screens or a split Window with tab navigation. Each interface has its advantages—they are described in the next sections.

This manual describes how to use the HP web browser interface (chapter 3) and the switch console (chapter 4), and how to configure the switch using either interface (chapter 6).

To use HP TopTools for Hubs & Switches, refer to the HP TopTools User’s Guide and the TopTools online help, both of which are available on the CDROM shipped with your HP switch.

Configuring an IP Address on the Switch

This chapter helps you to quickly assign an IP (Internet Protocol) address and subnet mask to the switch. In the factory default configuration, the switch does not have an IP address and subnet mask, so it can be managed only by using a direct connection to the switch console.

Note

Configuring an IP address and subnet mask enables the switch to operate as a managed device in your network, giving you in-band (networked) access to these interfaces:

■ HP Web Browser Interface built into the switch

■ HP TopTools for Hubs & Switches—SNMP-based network management

software shipped with the switch

■ the switch console through a Telnet connection

For more information on this topic, refer to “IP Configuration” on page 6-5.

An IP address and subnet mask for the switch should be assigned by your network administrator and be compatible with the IP addressing used in your network. For more information about IP addressing, refer to “IP Configuration” on page 6-5.

If your network is a standalone network, your IP addressing and subnet mask scheme can be set up in any way that meets your local needs. However, if you will be connecting your network to other networks that use globally assigned IP addresses, refer to “Globally Assigned Network Addresses” on page 6-14.

Methods for Configuring an IP Address and Subnet Mask

Use either of the following two methods to configure the switch with an IP address and subnet mask compatible with your network:

■

Manually through the switch’s console: This is the easiest method when you are initially setting up the switch. The switch comes with a console cable that you can use to connect the switch to a PC running a VT-100 terminal emulator (such as HyperTerminal in Windows 95 or Windows NT), or to a VT-100 terminal. Refer to “Manually Configuring an IP Address”, below.

■

Configure your DHCP/Bootp server to support the switch: By default, the switch is configured to acquire an IP address configuration from a DHCP or Bootp server. To use DHCP/Bootp, refer to “DHCP/Bootp Operation” on page 6-10.

Manually Configuring an IP Address

This section describes how to use the switch console to configure an IP address.

1. Use the instructions in chapter 2, “Installing the Switch 212M and 224M” of your switch installation manual to connect a PC running a terminal emulator, or a terminal, to the Console port on the switch, and display the Main Menu.

2. From the console Main Menu, select:

2. Switch Management Access Configuration (IP, SNMP, Console) ...

1. IP Configuration

You will see the screen similar to the one shown in figure 2-2, but with the IP Address, Subnet Mask, and Gateway fields blank.

Using the HP Web Browser Interface

Overview

The HP web browser interface built into the switch lets you easily access the switch from a browser-based PC on your network. This lets you do the following:

■ optimize your network uptime by using the Alert Log and other diagnostic

tools

■ make configuration changes to the switch

■ maintain security by configuring usernames and passwords

Using the HP web browser interface to configure the switch is covered in chapter 6, “Configuring the Switch”. This chapter covers the following:

■ system requirements for using the HP web browser interface (page 3-2)

■ starting a web browser interface session (page 3-3)

■ tasks for your first HP web browser interface session (page 3-6)

• configuring user names and passwords in the web browser interface

(page 3-8)

• selecting the fault detection configuration for the Alert Log operation

(page 3-25)

• getting access to online help for the web browser interface (page 3-10)

■ Description of the web browser interface:

• the Overview window and tabs (page 3-12)

• the Port Utilization and Status displays (page 3-14)

• the Alert Log and Alert types (page 3-16)

• setting the Fault Detection Policy (page 3-25)

Using the HP Web Browser

Interface

Note If you want security beyond that achieved with user names and passwords,

you can disable access to the web browser interface. This is done by changing the Web Agent Enabled parameter setting in the Console/Serial Link configuration screen in the switch console. See “Console/Serial Link” on page 6-20.

Using the HP Web Browser Interface

Starting an HP Web Browser Interface Session

You can start a web browser session in the following ways:

■ Using a standalone Web browser on a network connection from a PC or

UNIX workstation:

• Directly connected to your network

• Connected through remote access to your network

■ Using a management station running HP TopTools for Hubs & Switches

on your network (the same browser interface is presented when you access a device through HP TopTools)

Note

HP TopTools is designed for installation on a network management workstation. For this reason, the HP TopTools system requirements are different from the system requirements for accessing the switch’s web browser interface from a non-management PC or workstation. For HP TopTools requirements, refer to the information printed on the sleeve in which the HP TopTools CD is shipped, or to the system requirements information in the user’s guide included on the HP TopTools CD.

Using a Standalone Web Browser in a PC or UNIX Workstation

This procedure assumes that you have a supported web browser installed on your PC or workstation, and that an IP address has been configured on the switch. (For more on assigning an IP address, refer to chapter 2, “Configuring an IP Address on the Switch”.)

1. Make sure the Java not, do one of the following:

• In Netscape 4.03, click on E

Enable Java and Enable JavaScript options.

• In Microsoft Internet Explorer 4.x, click on View, Internet O

Security, C to the online Help for specific information on enabling the Java applets.

2. Type the IP address (or DNS name) of the switch in the browser Location or Address field and press [Enter]. (It is not necessary to include

http://) For example:

10.11.12.195 [Enter]

If you are using a Domain Name Server (DNS), your device may have a name associated with it (for example, switch20) that you can type in the Location or Address field instead of the IP address. Using DNS names typically improves browser performance. As such, we recommend that you assign a DNS name to each device that you access with the web browser interface.

The web browser interface automatically starts with the Status Overview window displayed for the selected device as shown in figure 3-1 on the next page.

Using HP TopTools for Hubs & Switches

For more on installing and using HP TopTools for Hubs & Switches, refer to the HP TopTools for Hubs & Switches booklet and CD-ROM that came with your switch.

Interface

Using the HP Web Browser

This procedure assumes the following:

■ You have installed the web browser recommended for HP TopTools on a

PC or workstation that serves as your network management station.

■ The networked device you want to access has been assigned an IP address

and, preferably, a DNS name and it has been discovered by HP TopTools. (For more on assigning an IP address, refer to chapter 2, “Configuring an IP Address on the Switch”.)

To establish a Web browser session with HP TopTools running, do the following on the network management station:

1. Make sure the Java

applets are enabled for your browser. If they are not, refer to the browser online help for specific information on enabling the Java applets.

2. Do one of the following tasks:

• On the HP TopTools Maps view, double-click on the symbol for the

networking device that you want to access.

• In HP TopTools, in the Topology Information dialog box, in the device

list, double-click on the entry for the device you want to access (IP address or DNS name).

Tasks for Your First HP Web Browser Interface Session

The first time you access the web browser interface, there are three tasks that you should perform:

■ review the “First Time Install” window

■ set Manager and Operator passwords

set access to the web browser interface online help

■

Viewing the “First Time Install” Window

When you access the switch’s web browser interface for the first time, the Alert Log contains a “First Time Install” alert, as shown in figure 3-1. This gives you information about first time installations, and provides an immediate opportunity to set passwords for security and to specify a Fault Detection policy, which determines the types of messages that will be displayed in the Alert Log.

Interface

Using the HP Web Browser

Double click on First Time Install in the Alert log (see above). The web browser interface then displays the “First Time Install” window, as shown in figure 3-2.

Creating User Names and Passwords in the Web Browser Interface

You may want to create both a user name and password to create access security for your switch. There are two levels of access to the interface that can be controlled by setting user names and passwords:

■ operator. An Operator-level user name and password allows read-only

access to most of the web browser interface, but prevents access to the Security window.

■ manager. A Manager-level user name and password allows full read/

write access to the web browser interface.

Asterisks indicate a password is configured

Figure 3-3. The Device Passwords Window

To set the passwords:

1. Access the Device Passwords screen by one of the following methods:

• If the Alert Log includes a “First Time Install” event entry, double

click on this event, then, in the resulting display, click on the secure access to the device link.

• Select the Security tab.

2. Click in the appropriate box in the Device Passwords window and enter user names and passwords. You will be required to repeat the password strings in the confirmation boxes.

Using the HP Web Browser Interface

Tasks for Your First HP Web Browser Interface Session

Both the user names and passwords can be up to 16 printable ASCII characters. Spaces can be included in user names, but not in passwords (to represent spaces in passwords, you can use the underscore (_) character).

3. Click on [Apply Changes] to activate the user names and passwords.

Note

Strings you assign in the web browser interface will overwrite previous access strings assigned in either the web browser interface or the switch console.

Using the Passwords

The manager and operator passwords are used to control access to both the web browser interface and the switch console. Once set, you will be challenged to supply the password every time you try to access either the web browser interface or switch console. The password you enter determines the capability you have during that session:

■ using the manager password gives you full read/write capabilities

■ using the operator password gives you read and limited write capabilities.

Using the User Names

If you also set user names in the web browser interface screen, you must supply the correct user name and password combination for web browser interface access. If a user name has not been set, the User Name field in the web browser interface access popup must be left blank.

The switch console uses only the passwords and does not prompt you for the User Names.

If You Lose a Password

Using the HP Web Browser

Interface

If you lose the passwords, you can clear them by pressing the Clear button on the front of the switch. This action deletes all password and user name protection for both the web browser interface and the switch console.

The Clear button is provided for your convenience, but its presence means that if you are concerned with the security of the switch configuration and operation, you should make sure the switch is installed in a secure location, such as a locked wiring closet.

Online Help for the HP Web Browser Interface

Online help is available for the web browser interface. You can use it by clicking on the question mark in the upper right corner of any of the web browser interface screens. Context sensitive help is provided for the screen you are on.

Providing Online Help. The Help files are automatically available if you install HP TopTools for Hubs & Switches on your network, of if you have Internet access to the World Wide Web, and the Internet connection is running. The Help files are included with HP TopTools for Hubs & Switches, and are also available from an HP World Wide Web site.

Retrieval of the Help files, as described above, is controlled by automatic entries in the Management Server URL field on the Configuration / Support URLs screen, shown in figure 3-4 on page 3-11. The switch is shipped with the URL set to the HP World Wide Web site. However, if HP TopTools for Hub & Switches is installed on a management station in your network, and TopTools discovers your switch, the Management Server URL value is automatically changed to point to the management station to retrieve the help.

If Online Help Fails to Operate. Do one of the following:

■ If HP TopTools for Hubs & Switches is installed and running on your

network, in the Management Server URL field, enter the IP address or DNS name of the network management station.

■ If you have World Wide Web access from your PC or workstation and do

not have HP TopTools installed, enter the following URL in the Server Management URL field:
