Initial Configuration for the Switch
User Guide

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, 50­60 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?

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:

Step 7
Save configuration and then verify running-configuration
Example:

Step 8
Ping an interface using the Ethernet management interface through the VRF
Switch# ping vrf Mgmt-vrf 192.168.0.1
Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds: .!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/1 ms Switch#
*Aug 17 21:18:45.152: %PNP-6-PNP_DISCOVERY_STOPPED: PnP Discovery stopped (Config Wizard)

You have now completed the initial configuration of the switch, so you can now configure other interfaces and features over a network connection without having to directly connect to the console port of the supervisor module.
To use the CLI to perform additional configuration or management tasks, enter commands at the Switch> prompt through the console port by using a terminal program or through the network by using Telnet. For configuration information, see the switch software configuration guide along with the switch command reference.

Configuring the Switch in the ROMMON Mode

Procedure
Step 1
The system is setup for autoboot. In order to change network parameters in the ROMMON, connect the console to system and while system is booting, after you see the the promt, press CTRL+C to stop booting and access ROMMON prompt.
