Bringing Up a Cisco Router

Bringing Up a Cisco Router involves pluging in the power cord inlet into the provided port, and then plug the the power cord terminals into a power source. The next thing is to power on the router by pressing the power button provided on the router. When you first bring up a Cisco router, youe will hear a high exhaling sound fro the router and then  it will start running what is known as  a power-on self test (POST),
and if that passes, it will look for and load the Cisco IOS

from Flash memory if a file is present. Flash memory is an electronically erasable programmable read-only memory (EEPROM).

The IOS will load and then look  for a valid configuration called startup-config that is stored by default in

nonvolatile RAM (NVRAM).

If there is no configuration in NVRAM, then the router will bring up what

is called setup mode

setup mode is a step-by-step process to help you configure a router.

You can also enter setup mode at any time from the command line by

typing the command


from global configuration mode. Setup only covers

some very global commands, but is helpful if you don’t know how to configure

certain protocols, like bridging or DECnet, for example.

Setup Mode

You actually have two options when using setup mode:

Basic Management and Extended Setup

Basic Management only gives you enough configurations to allow connectivity to the router, whereas Extended Setup allows you to configure some global parameters as well as interface configuration parameters.
