Cisco Systems Cisco 12816 Manuale Utente

For example, during the configuration of a POS interface, (using the setup facility 
initial router startup), the script appears as the following example as you respond 
to queries:

Configuring interface POS1/0:

  Is this interface in use?: yes

  Configure IP on this interface?: yes

In this example, the script does not display default or current parameters in square 
brackets [ ], because you entered the setup facility automatically at startup and 
there is no prior configuration information.

Conversely, when you enter the setup command at the privileged EXEC mode 
prompt (assuming that the POS interface has been configured previously), the 
script displays those settings in square brackets [ ].

Configuring interface POS1/0:

  Is this interface in use?[yes]:

  Configure IP on this interface?[yes]:

When a system prompt contains an existing value in square brackets, press 
Return to accept the value, or type an alternate value and press Return.

When you first enter the setup facility or enter the setup command, the system 
prompts you to configure global parameters for your router. Global parameters 
control system-wide settings, including the following:

Host name for the router.

Passwords for the enable, enable secret, and virtual terminal security 
parameters.

Protocols used by the router.
