Applying a Basic Configuration
The following exercise will walk you through a basic configuration.
First, enter global configuration mode.
Router#
config t
Next, apply a unique host name to the router. Use R1 for this example.
Router(config)#
hostname R1
Now, configure the password that is to be used to enter privileged EXEC mode. Use class as the pass-
word.
Router(config)#
enable secret class
Next, configure the console and Telnet lines with the password cisco. The console commands follow:
R1(config)#
line console 0
R1(config-line)#
password cisco
R1(config-line)#
login
The Telnet lines use similar commands:
R1(config)#
line vty 0 4
R1(config-line)#
password cisco
R1(config-line)#
login
