My-Router(config)# interface GigabitEthernet 0/1
My-Router(config)# interface GigabitEthernet 0/0 From Global Configuration Mode you need to enter into Interface Configuration Mode: The most basic parameter for a Router Interface is the IP address. This is an essential step in order for your router to be able to forward packets in the network. Step3: Configure IP addresses for Router Interfaces Notice that your Router prompt changes to the new hostname that you have just set. To differentiate your Router from other devices in the network, you should configure a Hostname for your device. Here I’m explaining how to configure this specific setup. Some people prefer to create also local user accounts (usernames and passwords) on the router itself in order to authenticate to the device. Router(config-line)# password “strongTelnetPass” It is suggested also to configure a password for the Telnet Lines (VTY lines) which will secure your access when connecting via Telnet over the network. Router(config)# enable secret “somestrongpassword”įrom now on, when you log in from user EXEC mode you will be asked for a password. Here we will configure the Enable Secret password that you will be using from now own to enter into Privileged EXEC Mode from User EXEC Mode. In Global Configuration Mode you configure parameters that affect the whole router device. Router# configure terminal <– Privileged EXEC mode The first step is to secure your access to the router by configuring a global secret password and also passwords for Telnet or Console as needed.Įnter into Global Configuration mode from the Privileged EXEC mode: I assume that you already have some basic knowledge of CLI and how to navigate between different configuration modes (user mode, privileged exec mode etc), so let’s get started: Step-by-Step Configuration of Cisco Routers Step1: Configure Access Passwords Router(config-line)# <– Line Configuration Mode Router(config-if)# <– Interface Configuration Mode Router(config)# <– Global Configuration Mode The basic CLI modes that we will be referring below are as following:
Mastering the Cisco Router CLI is essential for more complex configuration tasks and it is the most important knowledge you should acquire if you want to become a Cisco network administrator. However, in this post I will show you how to do this basic setup with the Command Line Interface ( CLI). When you first power up a new Cisco Router, you have the option of using the “setup” utility which allows you to create a basic initial configuration. It is a step-by-step guide for the most basic configuration commands needed to make the router operational. This post is by no means an exhaustive tutorial about Cisco Routers and how to configure their numerous features.
