Configuring the Switch

This appendix provides a command-line interface (CLI)-based setup procedure for a switch.

Before connecting the switch to a power source, review the safety warnings in Warnings

To connect a PC to the console port of the switch, see “Connecting a PC or Terminal to the Console Port” section.

Entering the Initial Configuration Information

To set up the switch, you need to complete the setup program, which runs automatically after the switch is powered on. You must assign an IP address and other configuration information necessary for the switch to communicate with the local routers and the Internet. This information is also required if you plan to use Device Manager or Cisco Network Assistant to configure and manage the switch.

IP Settings

You need this information from your network administrator before you complete the setup program:

  • Switch IP address
  • Subnet mask (IP netmask)
  • Default gateway (router)
  • Enable secret password
  • Enable password
  • Telnet password

Completing the Setup Program

To complete the setup program and to create an initial configuration for the switch:

Step 1 Enter Yes at these two prompts:

Would you like to enter the initial configuration dialog? [yes/no]: yes
 
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
 
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system.
 
Would you like to enter basic management setup? [yes/no]: yes
 

Step 2 Enter a hostname for the switch, and press Return.

On a command switch, the hostname is limited to 28 characters; on a member switch, it is limited to 31 characters. Do not use -n , where n is a number, as the last character in a hostname for any switch.

Enter host name [Switch]: host_name
 

Step 3 Enter an enable secret password, and press Return.

The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows spaces, but ignores leading spaces. The secret password is encrypted, and the enable password is in plain text.

Enter enable secret: secret_password
 

Step 4 Enter an enable password, and press Return.

Enter enable password: enable_password
 

Step 5 Enter a virtual terminal (Telnet) password, and press Return.

The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores leading spaces.

Enter virtual terminal password: terminal-password
 

Step 6 (Optional) Configure Simple Network Management Protocol (SNMP) by responding to the prompts. You can also configure SNMP later through the CLI, Device Manager, or the Cisco Network Assistant application. To configure SNMP later, enter no .

Configure SNMP Network Management? [no]: no
 

Step 7 Enter the interface name (physical interface or VLAN name) of the interface that connects to the management network, and press Return . For this release, always use vlan1 as that interface.

Enter interface name used to connect to the
management network from the above interface summary: vlan1
 

Step 8 Configure the interface by entering the switch IP address and subnet mask and pressing Return. The IP address and subnet masks shown here are examples.

Configuring interface vlan1:
Configure IP on this interface? [yes]: yes
IP address for this interface: 10.4.120.106
Subnet mask for this interface [255.0.0.0]: 255.0.0.0
 

Step 9 Enter Y to configure the switch as the cluster command switch. Enter N to configure it as a member switch or as a standalone switch.

If you enter N , the switch appears as a candidate switch in the Cisco Network Assistant GUI. You can configure the switch as a command switch later through the CLI, Device Manager, or the Cisco Network Assistant application. To configure it later, enter no .

Would you like to enable as a cluster command switch? [yes/no]: no
 

You have now completed the initial configuration of the switch, and the switch displays its initial configuration script:

The following configuration command script was created:
 
hostname Switch
enable secret 5 $1$ZQRe$DPulYXyQLm77v/a4Bmu6Y.
enable password cisco
line vty 0 15
password cisco
no snmp-server
!
!
interface Vlan1
no shutdown
ip address 10.4.120.106 255.0.0.0
!
interface FastEthernet1/1
!
interface FastEthernet1/2
!
interface FastEthernet1/3
!
...(output abbreviated)
!
interface GigabitEthernet1/1
!
interface GigabitEthernet1/2
!
end
 

Step 10 These choices appear:

[0] Go to the IOS command prompt without saving this config.
 
[1] Return back to the setup without saving this config.
 
[2] Save this configuration to nvram and exit.
 
If you want to save the configuration and use it the next time the switch reboots, save it in NVRAM by selecting option 2.
 
Enter your selection [2]:2
 

Make your selection, and press Return .
