This chapter provides information and instructions for configuring the switch. You must connect a serial console to the switch to begin configuration.
This chapter contains the following topics:
Default Settings
- The switch is configured with all ports enabled, set to auto-negotiate, mtu of 1518, and in Layer 2 MAC switching mode
- All ports are in VLAN 1
- DHCP client is enabled on the out-of-band management port
- Telnet acess enabled
- HTTP access enabled
- SNMP read-only community “public”
- SNMP read-write community “private”
Initial Configuration
By default, DHCP on OOB management port is enabled, and it’s possible to directly telnet into the OOB management interface to configure the switch, if DHCP server is running. You can use a DHCP server, switch serial console, or SNMP discovery to determine which IP address it reports, and use that address to telnet.
The initial configuration procedure is based on the following assumptions:
- The switch was not configured before and is in the same state as when you received it.
- The switch booted successfully.
- The console connection was established, and the console prompt appeared on the screen of a VT100 terminal or terminal equivalent.
The initial switch configuration is performed through the console port. After the initial configuration, you can manage the switch either from the already-connected console port or remotely through an interface defined during the initial configuration.
| Note - The switch is not configured with a default user name and password.
|
| Note - All of the settings that follow are necessary to allow remote management of the switch through Telnet (Telnet client) or HTTP (Web browser).
|
 Obtain Configuration Information
|
Before setting up the initial configuration of the switch, obtain the following information from your network administrator:
- The IP address to be assigned to the management interface through which the switch is managed.
- The IP subnet mask for the network.
- The IP address of the default gateway.
In-band and Out-of-band Connectivity
Ask the system administrator to determine whether you will configure the switch for in-band or out-of-band connectivity.
Initial Access Configuration
Initial configuration of the Netra CP3240 switch must be done either through the serial console port or though the out-of-band Ethernet management port.
MGMT Serial Configuration
You can use a locally or remotely attached terminal to configure in-band and out-of-band management through the MGMT serial port.
1. To use a locally attached terminal, attach one end of a null-modem serial cable to the MGMT serial port of the switch and the other end to the COM port of the terminal or workstation.
2. For remote attachment, attach one end of the serial cable to the MGMT serial port of the switch and the other end to the modem.
3. Set up the terminal for VT100 terminal emulation.
a. Set the terminal ON.
b. Launch the VT100 application.
c. Configure the COM port as follows:
i. Set the data rate to 9600 baud.
ii. Set the data format to 8 data bits, 1 stop bit, and no parity.
iii. Set the flow control to none.
iv. Select the proper mode under Properties.
v. Select Terminal keys.
The Log-in User prompt displays when the terminal interface initializes.
4. Enter an approved user name and password.
The default is admin for the user name and the password is blank.
The switch is installed and loaded with the default configuration.
Configuring for In-band Connectivity
In-band connectivity allows you to access the switch from a remote workstation. To use in-band connectivity, you must configure the switch with IP information (IP address, subnet mask, and default gateway).
|
Using DHCP
|
1. Enter the following command over the MGMT serial port to enable DHCP client:
You can assign IP information over the network through BootP or DHCP. Check with your system administrator to determine whether BootP or DHCP is enabled.
You need to configure the BootP or DHCP server with information about the switch --obtain this information through the serial port connection using the show network command. Set up the server with the following values.
|
Value
|
Description
|
|
IP address
|
Unique IP address for the switch. Each IP parameter is made up of four decimal numbers, ranging from 0 to 255. The default for all IP parameters is zeroes (0.0.0.0).
|
|
Subnet
|
Subnet mask for the LAN
|
|
Gateway
|
IP address of the default router, if the switch is a node outside the IP range of the LAN
|
|
MAC address
|
MAC address of the switch
|
When you connect the switch to the network for the first time after setting up the BootP or DHCP server, it is configured with the information supplied above. The switch is ready for in-band connectivity over the switched network.
If you do not use BootP or DHCP, access the switch through the EIA-232 port, and configure the network information as described below.
|
Using a Static IP
|
1. Enter the following command to allow a static IP:
2. Set the IP address, subnet mask, and gateway address by issuing the following command:
network IP <ipaddress> <netmask> [<gateway>]
|

|
|
Subnet
|
Subnet mask for the LAN
|
|
Gateway
|
IP address of the default router, if the switch is a node outside the IP range of the LAN
|
Configuring for Out-Of-Band Connectivity
Out-of-band connectivity allows you to access the switch from a remote workstation using the Ethernet network over a private network. To use Out-of-band connectivity, you must configure the switch with IP information (IP address, subnet mask, and default gateway).
|
Using DHCP
|
DHCP is enabled by default on the Netra CP3240 switch.
You need to configure the BootP or DHCP server with information about the switch --obtain this information through the serial port connection using the show serviceport command. Set up the server with the following values:
|
Value
|
Description
|

Saving Settings
1. To enable these changes to be retained during a reset of the switch, type CTRL+Z to return to the main prompt, type save config at the main menu prompt, and type y to confirm the changes.
2. To view the changes and verify out-of-band information, issue the command: show network.
3. The switch is configured for out-of-band connectivity and ready for Web-based and remote console management.
Quick Start
1. Turn the Power ON.
2. Allow the device to load the software until the login prompt appears. The device initial state is called the default mode.
3. When the prompt asks for operator login, do the following steps:
a. Type admin at the login prompt.
Because a number of the Quick Setup commands require administrator account rights, log into an administrator account.
Do not enter a password because the default mode does not use a password - after typing admin, press Enter two times.
b. The CLI User EXEC prompt is displayed.
i. Type enable to switch to the Privileged EXEC mode from User EXEC.
ii. Type configure to switch to the Global Config mode from Privileged EXEC.
iii. Type exit to return to the previous mode.
iv. Enter ? to show a list of commands that are available in the current mode.
4. If you want to access the switch remotely, configure the switch for In-band or Out-of-Band connectivity.
You must configure the device with IP information (IP address, subnet mask, and default gateway).
System Information and System Setup
This section describes the commands you use to view system information and to setup the network device. The tables below contain the Quick Start commands that allow you to view or configure the following information:
- Software versions
- Physical port data
- User account management
- IP address configuration
- Uploading from Networking Device to Out-of-Band PC
- Downloading from Out-of-Band PC to Networking Device
- Downloading from TFTP Server
- Restoring factory defaults
For each of these tasks, a table shows the command syntax, the mode you must be in to execute the command, and the purpose and output of the command. If you configure any network parameters, you should execute the following command:
copy system:running-config nvram:startup-config
|
This command saves the changes to the configuration file. You must be in the correct mode to execute the command. If you do not save the configuration, all changes are lost when you power down or reset the networking device. In a stacking environment, the running configuration is saved in all units of the stack.
