Breaking Out Of IOS Initial Configuration Dialog and Who The Hell Uses This Anyways???

The other day I somehow got trapped in the IOS initial configuration dialog.  I must have typed ‘y’ when I meant ‘n’ at some point.  Anyooo…I was quickly routed to initial configuration hell:

[Resuming connection 4 to r4 … ]

% Please answer ‘yes’ or ‘no’.
Would you like to enter basic management setup? [yes/no]: no

First, would you like to see the current interface summary? [yes]: y

Any interface listed with OK? value “NO” does not have a valid configuration

Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            unassigned      NO  unset  up                    up
Serial0/0                  unassigned      NO  unset  up                    down
FastEthernet0/1            unassigned      NO  unset  up                    up
Serial0/1                  unassigned      NO  unset  down                  down

Configuring global parameters:

  Enter host name [Router]:

  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.

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

  The virtual terminal password is used to protect
  access to the router over a network interface.

Async lines accept incoming modems calls. If you will have
users dialing in via modems, configure these lines.

AutoSecure dialog can be started later using “auto secure” CLI

I used control+c to break out.  I’m not sure if this is the ‘official’ or only break sequence, but it worked.

Configuration aborted, no changes made.


Press RETURN to get started!

Has anyone – anywhere – at any time – EVER configured a router using the initial configuration dialog?



  1. I did once. Think of it kind of like touching a hot stove when you are a kid. You do it once so you can learn to never do it again.

    One of the big problems I saw with it that immediately made me recommend it not being used is that it makes you set both ‘enable’ and ‘enable secret’ passwords. And they both have to be different.

  2. Yes, In case I was asked a question about it on the CCNA exam. 🙂

  3. Yep, had to roll out a thousand odd routers in one go. So built an inverse arp frame-relay auto-boot/config head end, and then documented the setup routine for the field engineers as they moved across the country. If they knew how to use the CLI they could do that, if they didn’t they used the auto-setup.

  4. Oh, I did back in 1991 (using Cisco Software 8.3 … there was no IOS then). It was pretty handy as I had to configure a router in a hurry and had never seen Cisco boxes (or their manuals) before.

  5. Yep – When I was 10 (I wish it were back in ’91). 🙂
