Power on a Cisco device

When you first power-on a newly purchashed Cisco device, it will perform a power-on self-test (POST) to discover the hardware components and verify that all components work properly. If the POST is successful, the device will enter the setup mode. This mode presents a step-by-step dialog to help you configure some basic parameters, such as the device hostname, passwords, interface IP address, etc. To enter the setup mode, power on your device and type yes when prompted to make a selection:

         --- System Configuration Dialog ---

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
Configuring global parameters:

  Enter host name [Router]: R1

  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: secret

  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: cisco

  The virtual terminal password is used to protect
  access to the router over a network interface.
  Enter virtual terminal password: cisco
Configure SNMP Network Management? [no]:no

Current interface summary

Interface              IP-Address      OK? Method Status                Protocol

GigabitEthernet0/0     unassigned      YES manual administratively down down

GigabitEthernet0/1     unassigned      YES manual administratively down down

GigabitEthernet0/2     unassigned      YES manual administratively down down

Vlan1                  unassigned      YES manual administratively down down

Enter interface name used to connect to the
management network from the above interface summary: GigabitEthernet0/2

Configuring interface GigabitEthernet0/2:
  Configure IP on this interface? [yes]: yes
    IP address for this interface:
    Subnet mask for this interface [] : 

The following configuration command script was created:

hostname R1
enable secret 5 $1$mERr$5jbOD5lHVUWxAAsNOD6eO/
enable password cisco
line vty 0 4
password cisco
interface Vlan1
 no ip address
interface GigabitEthernet0/0
 no ip address
interface GigabitEthernet0/1
 no ip address
interface GigabitEthernet0/2
 no shutdown

[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.

Enter your selection [2]: 2
Building configuration...
Use the enabled mode 'configure' command to modify this configuration.

Press RETURN to get started!


The wizard guides you through the initial configuration of your device and will create an initial configuration file. The setup mode is useful when you are unfamiliar with the IOS CLI, but once you learn the basics of CLI, you probably won’t use this mode ever again.

You can enter the setup mode at any time from the command line by typing the setup command from the privileged mode. To exit the setup mode without saving any changes, press CRTL+C.
