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

26CHAPTER 1: GETTING STARTED

■Your DHCP server does not allow you to allocate static IP addresses. (Static IP addresses are necessary to ensure that the switch is always allocated the same IP information.)

	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.
Using the	You can access the switch through the Console port to manually set the

	Guide.

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

Manually set the IP Address using the Console Port

1Connect the workstation to the console port using the console cable as shown in Figure 7.

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

To connect the cable:

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

bAttach the other end of the cable to the workstation.

2Open 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)

■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.

3Power 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

28CHAPTER 1: GETTING STARTED

1Connect to the switch Console port as described in “Connecting to the Console Port” page 26.

2The 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.

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

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

5Enter 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 mmm.mmm.mmm.mmm

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

6Enter 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.

Viewing IP This section describes how to view the automatically allocated IP Information using the information using the command line interface. The automatic IP
