Initial Configuration for the Switch

Options for Initial Configuration

After you complete the hardware installation, you need to setup the switch with configuration required to enable traffic to pass through the network. On your first day with your new device, you can perform a number of tasks to ensure that your device is online, reachable and easily configured.

When the supervisor module is shipped, the factory default setting for MANUAL_BOOT is no. This means that when you first power on the device, it will always boot automatically. So these are the first options available to you for initial configuration:

  • Configuring the Switch Using the Web User Interface

  • Configuring the Switch Using the CLI

  • Configuring the Switch in the ROMMON Mode

    This option requires you to interrupt autoboot (factory default) and enter the ROMMON prompt to enter the required settings. Use this option if you want to boot the system by using an image that is located on a TFTP server.

Configuring the Switch Using the Web User Interface

For instructions on setting up the switch using the WebUI, refer to the required version of the software configuration guide. In the guide, go to Configuring the Switch Using the Web User Interface.

Configuring the Switch Using the CLI

Starting the Terminal-Emulation Software

To start the terminal emulation software, follow these steps:

Before you begin

The terminal-emulation software—frequently a PC application such as Hyperterminal or ProcommPlus—makes communication between the switch and your PC or terminal possible.

Procedure


Step 1

Start the terminal-emulation program if you are using a PC or terminal.

Step 2

Start a terminal-emulation session.

Step 3

Configure the baud rate and character format of the PC or terminal to match these console port default characteristics:

  • 9600 baud

  • 8 data bits

  • No flow control

  • 1 stop bit

  • No parity


What to do next

Connect to a power source.

Connecting to a Power Source

To connect to a power source, follow these steps:

Procedure


Step 1

Connect one end of the supplied country-specific AC power cord to the power connector on the switch.

Step 2

Plug the other end into a grounded 100 to 240 VAC, 50–60 Hz AC outlet.

The switch powers on.

If you started the terminal-emulation program before you powered on your switch, the PC or terminal displays the bootloader sequence. You need to press Enter to display the setup program prompt.


What to do next

Obtain IP settings from your network administrator.

Connecting the RJ-45 Console Port

To use the console port to perform the initial configuration, connect the switch console port to a PC that uses a VT-100 terminal emulator. Use an RJ-45-to-DB-9 adapter cable for this.

To connect the PC or terminal to the switch, follow these steps:

Procedure


Step 1

Using an RJ-45-to-DB-9 adapter cable, insert the RJ-45 connector into the console port that is located on the front panel of the supervisor module.

Step 2

Attach the DB-9 female DTE of the adapter cable to a PC serial port, or attach an appropriate adapter to the terminal.


Connecting the USB Console Port

Procedure


Step 1

.

Note

 

USB Type A port on the switch provides file system support and is NOT a console port. See USB Type A Port section.

Step 2

Connect a USB cable to the PC USB port. Connect the other end of the cable to the switch mini-B (5-pin-connector) USB console port.

Step 3

Start the terminal-emulation program on the PC or the terminal. The program, frequently a PC application such as Putty or TeraTerm, makes communication between the switch and your PC or terminal possible.

Step 4

Configure the baud rate and character format of the PC or terminal to match the console port default characteristics:

  • 9600 baud

  • 8 data bits

  • 1 stop bit

  • No parity

  • None (flow control)

Step 5

Power on the switch as described in the switch getting started guide.

Step 6

The PC or terminal displays the bootloader sequence. Press Enter to display the setup prompt. Follow the steps in the Setup program.


IP Settings

To set up the switch, you need to assign an IP address and other configuration information necessary for the switch to communicate with the local routers and the Internet.

You will need this information from your network administrator:

  • Switch IP address

  • Subnet mask (IP netmask)

  • Default gateway (router)

  • TFTP Server

Performing the Initial Configuration

The bootup script runs the configuration wizard, which prompts you for basic configuration input. At any point you may enter a question mark '?' for help. Use Ctrl+C to abort the configuration dialog at any prompt. Default settings are in square brackets '[ ]'.

Procedure


Step 1

Respond to whether you would like to enter the initial configuration dialog

Example:

Would you like to enter the initial configuration dialog? [yes/no]: yes

Step 2

Repond to whether you would like to enter basic management setup

Example:

Would you like to enter basic management setup? [yes/no]: yes

Step 3

Repond to whether you would like to enter basic management setup

Example:

Would you like to enter basic management setup? [yes/no]: yes
Configuring global parameters:
Enter host name [Switch]: Switch

  The enable secret is a password used to protect access to
  privileged EXEC and configuration modes. This password, after
  entered, becomes encrypted in the configuration.
  Enter enable secret: examplesecret

  The enable password is used when you do not specify an
  enable secret password, with some older software versions, and
  some boot images.
  Enter enable password: exampleenable

  The virtual terminal password is used to protect
  access to the router over a network interface.
  Enter virtual terminal password: examplevtp
Setup account for accessing HTTP server? [yes]: yes
    Username  [admin]: 
    Password  [cisco]: 
    Password is UNENCRYPTED.
  

Step 4

Repond to whether you would like to set up an account to access the HTTP server.

Example:

Setup account for accessing HTTP server? [yes]: yes
    Username  [admin]: 
    Password  [cisco]: 
    Password is UNENCRYPTED.
  

Step 5

Repond to whether you would like to configure SNMP network management.

Example:

Configure SNMP Network Management? [no]: no 

Step 6

The system displays the interface summary. From the list, enter the interface name used to connect to the management network, and then enter the IP address and subnet mask for the interface

Example:


Current interface summary
Any interface listed with OK? value "NO" does not have a valid configuration

Interface              IP-Address      OK? Method Status                Protocol
Vlan1                  unassigned      NO  unset  up                    up      
GigabitEthernet0/0     unassigned      NO  unset  up                    up      
GigabitEthernet1/0/1   unassigned      YES unset  down                  down    
<output truncated>

Enter interface name used to connect to the
management network from the above interface summary: GigabitEthernet0/0

Configuring interface GigabitEthernet0/0:
  Configure IP on this interface? [yes]: 
    IP address for this interface: 192.168.247.10
    Subnet mask for this interface [255.255.255.0] : 255.255.0.0
    Class C network is 192.168.247.0, 16 subnet bits; mask is /16

The following configuration command script was created:
