Setup Mode

Starts automatically if no startup configuration present.

Router#setup

Enters startup mode from the command line

Note:

The answer inside the square brackets [ ] is the default answer. If this is the answer you want, just press .

Pressing at any time will end the setup process, shut down all interfaces, and take you to user mode (Router>).

Note:

Setup mode cannot be used to configure an entire router. It does only the basics. For example, you can only turn on either RIPv1 or IGRP, but not OSPF or EIGRP. You cannot create ACLs here or enable NAT. You can assign an IP address to an interface, but not a subinterface. All in all, setup mode is very limiting.

Entering setup mode is not a recommended practice. Instead, you should use the command-line interface (CLI), which is more powerful:

Would you like to enter the initial configuration dialog? [yes] : no Would you like to enable autoinstall? [yes] no 

Autoinstall is a feature that will try and broadcast out all interfaces to try and find a configuration. If you say yes, you will have to wait for a few minutes while it looks for a configuration to load. Very frustrating. Say no.
