1 Overview
The 3Com baseline switch 2900 family can be configured through the command line interface (CLI),
web interface, and SNMP/MIB. These configuration methods are suitable for different application
scenarios.
z The web interface supports all switch 2900 series configurations.
z The CLI provides some configuration commands to facilitate your operation. To perform other
configurations not supported by the CLI, use the web interface.
2-1
2 Configuration Through the Web Interface
Web-Based Network Management Operating Environment
3Com provides the Web-based network management function to facilitate the operations and
maintenance on 3Com’s network devices. Through this function, the administrator can visually manage
and maintain network devices through the Web-based configuration interfaces.
Figure 2-1
shows a Web-based network management operating environment.
Figure 2-1 Web-based network management operating environment
Logging In to the Web Interface
Default Login Information
The device is provided with the default Web login information. You can use the default information to log
in to the Web interface.
Table 2-1 The default Web login information
Information needed at login Default value
Username admin
Password None
IP address of the device (VLAN-interface 1)
Default IP address of the device, depending on the
status of the network where the device resides.
1) The device is not connected to the network, or no DHCP server exists in the subnet where the
device resides
If the device is not connected to the network, or no DHCP server exists in the subnet where the device
resides, you can get the default IP address of the device on the label on the right of the device rear
panel, as shown in Figure 2-2
. The default subnet mask is 255.255.0.0.
2-2
Figure 2-2 Default IP address of the device
2) A DHCP server exists in the subnet where the device resides
If a DHCP server exists in the subnet where the device resides, the device will dynamically obtain its
default IP address through the DHCP server. You can log in to the device through the console port, and
execute the summary command to view the information of its default IP address.
<Sysname> summary
Select menu option: Summary
IP Method: DHCP
IP address: 10.153.96.86
Subnet mask: 255.255.255.0
Default gateway: 0.0.0.0
<Omitted>
Example
Assuming that the default IP address of the device is 169.254.147.198, follow these steps to log in to the
device through the Web interface.
z Connect the device to a PC
Connect the GigabitEthernet interface of the device to a PC by using a crossover Ethernet cable (by
default, all interfaces belong to VLAN 1).
z Configure an IP address for the PC and ensure that the PC and device can communicate with each
other properly.
Select an IP address for the PC from network segment 169.254.0.0/16 (except for the default IP
address of the device), for example, 169.254.147.1.
z Open the browser, and input the login information.
On the PC, open the browser (it is recommended to use IE 5.0 or later), type the IP address
http://169.254.147.198 in the address bar, and press Enter to enter the login page of the Web interface,
as shown in Figure 2-3
. Input the username admin and the verification code, leave the password blank,
select the language (English and Chinese are supported at present), and click Login.
2-3
Figure 2-3 Login page of the Web interface
z The PC where you configure the device is not necessarily a Web-based network management
terminal. A Web-based network management terminal is a PC used to log in to the Web interface
and is required to be reachable to the device.
z After logging in to the Web interface, you can select Device > Users from the navigation tree,
create a new user, and select Wizard or Network > VLAN interface to configure the IP address of
the VLAN interface acting as the management interface. For detailed configuration, refer to the
corresponding configuration manuals of these modules.
z If you click the verification code displayed on the Web login page, you can get a new verification
code.
z Up to five users can concurrently log in to the device through the Web interface.
Logging Out of the Web Interface
Click Logout in the upper-right corner of the Web interface, as shown in Figure 2-4 to quit the web
console.
The system does not save the current configuration automatically. Therefore, you are recommended to
save the current configuration before logout.
Introduction to the Web Interface
The Web interface is composed of three parts: navigation tree, title area, and body area, as shown in
Figure 2-4
.
2-4
Figure 2-4 Web-based configuration interface
(1) Navigation tree (2) Body area (3) Title area
z Navigation tree: Organizes the Web-based NM functions as a navigation tree, where you can
select and configure functions as needed. The result is displayed in the body area.
z Body area: Allows you to configure and display features.
z Title area: Displays the path of the current configuration interface in the navigation tree; provides
the Help button to display the Web related help information, and the Logout button to log out of the
Web interface.
The Web network management functions not supported by the device will not be displayed in the
navigation tree.
Web User Level
Web user levels, from low to high, are visitor, monitor, configure, and management. A user with a
higher level has all the operating rights of a user with a lower level.
z Visitor: Users of this level can only use the network diagnostic tools ping and Trace Route. They
can neither access the device data nor configure the device.
z Monitor: Users of this level can only access the device data but cannot configure the device.
z Configure: Users of this level can access device data and configure the device, but they cannot
upgrade the host software, add/delete/modify users, or back up/restore configuration files.
z Management: Users of this level can perform any operations to the device.
Introduction to the Web-Based NM Functions
Table 2-2 describes the Web-based network management functions in detail.

Configuration Guidelines
z The Web-based console supports Microsoft Internet Explorer 6.0 SP2 and higher, but it does not
support the Back, Next, Refresh buttons provided by the browser. Using these buttons may result
in abnormal display of Web pages.
z When the device is performing spanning tree calculation, you cannot log in to or use the Web
interface.
z As the Windows firewall limits the number of TCP connections, when you use IE to log in to the
Web interface, sometimes you may be unable to open the Web interface. To avoid this problem, it
is recommended to turn off the Windows firewall before login.
2-14
z If the software version of the device changes, when you log in to the device through the Web
interface, you are recommended to delete the temporary Internet files of IE; otherwise, the Web
page content may not be displayed correctly.

3 Configuration Through the Command Line
Interface
z The 3Com baseline switch 2900 family can be configured through the command line interface (CLI),
web interface, and SNMP/MIB, among which the web interface supports all switch 2900 series
configurations. These configuration methods are suitable for different application scenarios. As a
supplementary to the web interface, the CLI provides some configuration commands to facilitate
your operation, which are described in this chapter. To perform other configurations not supported
by the CLI, use the web interface.
z You will enter user view directly after you log in to the device. Commands in the document are all
performed in user view.
Getting Started with the Command Line Interface
As a supplementary to the web interface, the CLI provides some configuration commands to facilitate
your operation. For example, if you forget the IP address of VLAN-interface 1 and cannot log in to the
device through the Web interface, you can connect the console port of the device to a PC, and
reconfigure the IP address of VLAN-interface 1 through the CLI.
This section describes using the CLI to manage the device.
Setting Up the Configuration Environment
Set up the configuration environment as follows:
Step1 Take the console cable out of the package. (A console cable is an 8-core shielded cable. One end of the
cable is a crimped RJ-45 connector, which is connected to the console port of the switch, and the other
end is a DB-9 female connector, which is connected to the serial port on the console terminal, as shown
below.)
3-2
Figure 3-1 Console cable
Step2 Plug the DB-9 female connector of the console cable to the serial port of the console terminal or PC.
Step3 Connect the RJ-45 connector of the console cable to the console port of the switch. (as shown below)
Figure 3-2 Network diagram for configuration environment setup
Console port
Serial port
Console cable
Pay attention to the mark on the console port and be sure to plug the connector to the correct port.
z When connecting a PC to a powered-on switch, you are recommended to connect the DB-9
connector of the console cable to the PC before connecting the RJ-45 connector to the switch.
z When disconnecting a PC from a powered-on switch, you are recommended to disconnect the
DB-9 connector of the console cable from the PC after disconnecting the RJ-45 connector from the
switch.
Setting Terminal Parameters
When setting up the configuration environment through the console port, the terminal or PC can use the
terminal emulation program to communicate with the switch. You can run the HyperTerminal of the
Windows operating system to connect to other PCs, network devices, and Telnet sites. For detailed
3-3
information and the use of the HyperTerminal, refer to the HyperTerminal Help documentation in Help
and Support Center on the PC running the Windows operating system.
In the following configuration procedure, Windows XP HyperTerminal is used to communicate with the
switch.
1) Start the PC and run the terminal emulation program.
2) Set terminal parameters as follows:
z Bits per second: 38,400
z Data bits: 8
z Parity: None
z Stop bits: 1
z Flow control: None
z Emulation: VT100
The specific procedure is as follows:
Step1 Select Start > Programs > Accessories > Communications > HyperTerminal to enter the
HyperTerminal window. The Connection Descriptio n dialog box appears, as shown below.
Figure 3-3 Connection description of the HyperTerminal
Step2 Type the name of the new connection in the Name text box and click OK. The following dialog box
appears. Select the serial port to be used from the Connect using drop-down list.
3-4
Figure 3-4 Set the serial port used by the HyperTerminal connection
Step3 Click OK after selecting a serial port. The following dialog box appears. Set Bits per second to 38400,
Data bits to 8, Parity to None, Stop bits to 1, and Flow control to None.
Figure 3-5 Set the serial port parameters
Step4 Click OK after setting the serial port parameters and the system enters the HyperTerminal window
shown below.

Figure 3-6 HyperTerminal window
Step5 Click Properties in the HyperTerminal window to enter the Switch Properties dialog box. Click the
Settings tab, set the emulation to VT100, and then click OK.

Description
Use the initialize command to delete the configuration file to be used at the next startup and reboot the
device with the default configuration being used during reboot.
Use the command with caution because this command deletes the configuration file to be used at the
next startup and restores the factory default settings.
Examples
# Delete the configuration file to be used at the next startup and reboot the device with the default
configuration being used during reboot.
<Sysname> initialize
The startup configuration file will be deleted and the system will be rebooted.Continue?

ipsetup
Syntax
ipsetup { dhcp | ip address ip-address { mask | mask-length } [ default-gateway ip-address ] }
Parameters
dhcp: Specifies the interface to obtain an IP address through DHCP.
ip-address ip-address: Specifies an IP address for VLAN-interface 1 in dotted decimal notation.
mask: Subnet mask in dotted decimal notation.
mask-length: Subnet mask length, the number of consecutive ones in the mask, in the range of 0 to 32.
default-gateway ip-address: Specifies the IP address of the default gateway or the IP address of the
outbound interface. With this argument and keyword combination configured, the command not only
assigns an IP address to the interface, but also specifies a default route for the device.
Description
Use the ipsetup dhcp command to specify VLAN-interface 1 to obtain an IP address through DHCP.
Use the ipsetup ip address ip-address { mask | mask-length } command to assign an IP address to
VLAN-interface 1.
By default, the device automatically obtains its IP address through DHCP; if fails, it uses the assigned
default IP address. See
Figure 2-2
for details.
If there is no VLAN-interface 1, either command creates VLAN-interface 1 first, and then specifies its IP
address.
Examples
# Create VLAN-interface 1 and specify the interface to obtain an IP address through DHCP.
<Sysname> ipsetup dhcp
# Create VLAN-interface 1 and assign 192.168.1.2 to the interface, and specify 192.168.1.1 as the
default gateway.
<Sysname> ipsetup ip-address 192.168.1.2 24 default-gateway 192.168.1.1
