Targeting a login account in routers:

Router(config)# username root secret My$Password

After targeting a user name, you must enable the use of the user name of the port. For example:

Router(config)# line con 0
Router(config-line)# login local
Router(config)# line aux 0
Router(config-line)# login local
Router(config)# line vty 0 4
Router(config-line)# login local

Set up a host name in routers:

Router(config)# hostname Router-Branch-23

You can configure a domain name in routers, so that it knows which DNS domain it is in.

For example: Router-Branch-23(config)# ip domain name TechRepublic.com

To enter the privilege mode Password:

Router(config)# enable secret My$Password

Encryption router password:

Router(config)# service password-encryption
