Setting Up for Management 21

Setting Up for Management

To make full use of the features offered by your switch, and to change and monitor the way it works, you have to access the management software that resides on the switch. This is known as managing the switch. Managing the switch can help you to improve the efficiency of the switch and therefore the overall performance of your network.

This section explains the initial set up of the switch and the different methods of accessing the management software to manage a switch. It covers the following topics:

■ Methods of Managing a Switch

■ Switch Setup Overview

■ Using the Command Line Interface (CLI)

■ Manually set the IP Address using the Console Port

■ Viewing IP Information using the Console Port

■ Setting Up Web Interface Management

■ Setting Up Command Line Interface Management

■ Setting Up SNMP Management V1 or V2

■ Default Users and Passwords

Methods of Managing a Switch

To manage your switch you can use one of the following methods:

■ Web Interface Management

■ Command Line Interface Management

■ SNMP Management

You can use the Command Line Interface through the Console port for complete access to all operations of the switch including setting and viewing the IP address, configuring user accounts, upgrading switch firmware, and more. Refer to the 3Com CLI Reference Guide.

Each switch has an internal set of web pages that allow you to manage the switch using a Web browser remotely over an IP network (see Figure 2).

Figure 2 Web Interface Management over the Network

Refer to “Setting Up Web Interface Management” on page 30.

Each switch has a command line interface (CLI) that allows you to manage the switch from a workstation, either locally via a console port connection (see

Figure 3 CLI management via the console port

Figure 3), or remotely over the network (see Figure 4).

SNMP Management You can manage a switch using any network management workstation

running the Simple Network Management Protocol (SNMP) as shown in Figure 5. For example, you can use the 3Com Network Director software, available from the 3Com web site.

Figure 5 SNMP Management over the Network

Refer to “Setting Up SNMP Management V1 or V2” on page 32.

Switch Setup Overview

This section gives an overview of what you need to do to get your switch set up and ready for management when it is in its default state. The whole setup process is summarized in

Figure 6. Detailed procedural steps

are contained in the sections that follow. In brief, you need to:

■ Configure IP information manually for your switch or view the

automatically configured IP information

■ Prepare for your chosen method of management

“Default Users and

Passwords” on page 33.

Switch Setup Overview 25

IP Configuration The switch’s IP configuration is determined automatically using DHCP, or

manually using values you assign.

Automatic IP Configuration using DHCP

By default the switch tries to configure its IP Information without requesting user intervention. It tries to obtain an IP address from a DHCP server on the network.

Default IP Address If no DHCP server is detected, the switch will use its default IP information. The default IP address is 169.254.x.y, where x and y are the last two bytes of its MAC address.

Note: The switch’s default IP address is listed on a label located on the bottom and top of the switch.

If you use automatic IP configuration it is important that the IP address of the switch is static, otherwise the DHCP server can change the switch’s IP addresses and it will be difficult to manage. Most DHCP servers allow static IP addresses to be configured so that you know what IP address will be allocated to the switch. Refer to the documentation that accompanies your DHCP server.

You should use the Automatic IP configuration method if:

■ your network uses DHCP to allocate IP information, or

■ flexibility is needed. If the switch is deployed onto a different subnet, it

will automatically reconfigure itself with an appropriate IP address,

instead of you having to manually reconfigure the switch.

If you use the automatic IP configuration method, you need to discover the automatically allocated IP information before you can begin management. Work through the

“Viewing IP Information using the

Console Port” on page 28.

Manual IP Configuration

When you configure the IP information manually, the switch remembers the information that you enter until you change it again.

You should use the Manual IP configuration method if:

■ You do not have a DHCP server on your network, or

■ You want to remove the risk of the IP address ever changing, or

26 CHAPTER 1: GETTING STARTED

■ Your DHCP server does not allow you to allocate static IP addresses.

For most installations, 3Com recommends that you configure the switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP server, and eliminates the risk of the IP address changing.

To manually enter IP information for your switch, work through the “Manually set the IP Address using the Console Port” on page 27.

(Static IP addresses are necessary to ensure that the switch is always allocated the same IP information.)

Using the Command Line Interface (CLI)

Connecting to the

Console Port

You can access the switch through the Console port to manually set the IP address, or to view the IP address that was assigned automatically (for example, by a DHCP server).

For more information about the CLI, refer to the 3Com CLI Reference Guide.

This section describes how to connect to your switch through the Console port.

Prerequisites

■ A workstation with terminal emulation software installed, such as

Microsoft Hyperterminal. This software allows you to communicate with the switch using the console port directly.

■ Documentation supplied with the terminal emulation software.

■ The console cable (RJ-45 to DB-9) supplied with your switch.

You can find pin-out diagrams for the cable in Appendix C on page 235.

Using the Command Line Interface (CLI) 27

Connecting the Workstation to the Switch

1 Connect the workstation to the console port using the console cable as

shown in

Figure 7 Connecting a Workstation to the switch using the Console Port

Figure 7.

To connect the cable:

a Attach the cable’s RJ-45 connector to the Console port of the switch.

b Attach the other end of the cable to the workstation.

2 Open your terminal emulation software and configure the COM port

settings to which you have connected the cable. The settings must be set to match the default settings for the switch, which are:

■ 38,400 baud (bits per second)

Manually set the IP

Address using the

Console Port

■ 8 data bits

■ no parity

■ 1 stop bit

■ no hardware flow control

Refer to the documentation that accompanies the terminal emulation software for more information.

3 Power up the switch. The Power on Self Test (POST) will be performed.

The OfficeConnect Managed Fast Ethernet PoE Switch takes approximately two minutes to boot.

You are now ready to manually set up the switch with IP information using the command line interface.

■ You need to have the following information:

■ IP address

■ subnet mask

■ default gateway

28 CHAPTER 1: GETTING STARTED

1 Connect to the switch Console port as described in “Connecting to the

Console Port” page 26.

2 The command line interface login sequence begins as soon as the switch

detects a connection to its console port. When the process completes, the Login prompt displays.

3 At the login prompt, enter admin as your user name and press Return.

The Password prompt displays.

4 Press Return. If you have logged on correctly, the Console# prompt

should be displayed.

5 Enter the following commands to enter configuration mode, specify the

VLAN to which the IP address will be assigned, and then enter the IP address and subnet mask for the switch as follows:

Console#configure Console(config)#interface vlan 1 Console(config-if)#ip address xxx.xxx.xxx.xxx

(Note: xxx.xxx.xxx.xxx is the IP address and mmm.mmm.mmm.mmm is the subnet mask of the switch.)

mmm.mmm.mmm.mmm

6 Enter the end command to return to the Privileged Exec mode, and then

enter the quit command to terminate the CLI session.

The initial setup of your switch is now complete and the switch is ready for you to set up your chosen management method. See

“Methods of

Managing a Switch” on page 21.

This section describes how to view the automatically allocated IP

information using the command line interface. The automatic IP configuration process usually completes within one minute after the switch is connected to the network and powered up.

1 Connect to the switch Console port as described in “Connecting to the

Console Port” page 26.

The automatic IP configuration process usually completes within one minute.

2 The command line interface login sequence begins as soon as the switch

4 At the password prompt, press Return.If you have logged on correctly,

the Console# prompt is displayed.

5 Enter show ip interface to view a summary of the allocated IP address.

The following is an example of the displayed information.

Console#show ip interface IP Address and Netmask: 169.254.99.51 255.255.0.0 on VLAN 1, Address Mode: DHCP Console#

The initial set up of your switch is now complete and the switch is ready for you to set up your chosen management method. See

“Methods of

Managing a Switch” on page 21.

For more information about the CLI, refer to the 3Com CLI Reference Guide.

If you do not intend to use the command line interface using the console port to manage the switch, you can log out, disconnect the serial cable and close the terminal emulator software.
