Introduction to the Cisco IOS and SDM

Remember the difference between the enable password and enable secret password. Both

of these passwords are used to gain access into privileged mode. However, the enable secret

password is newer and is always encrypted by default. Also, if you set the enable password and

then set the enable secret, only the enable secret will be used.

Remember how to set the enable secret on a router. To set the enable secret, you use the

command enable secret. Do not use enable secret password password or you will set

your password to password password. Here is an example:

enable

config t

enable secret todd

Remember how to set the console password on a router. To set the console password, use

the following sequence:

enable

config t

line console 0

password todd

Remember how to set the Telnet password on a router. To set the Telnet password, the

sequence is as follows:

enable

config t

line vty 0 4

password todd

Remember how to set up SSH on a router. To set a router to use SSH instead of, or with,

Telnet, use the following steps:

1. Set your hostname:

Router(config)#hostname Todd

2. Set the domain name (both the hostname and domain name are required for the

encryption keys to be generated):

Todd(config)#ip domain-name Lammle.com

3. Generate the encryption keys for securing the session:

Todd(config)#crypto key generate rsa general-keys modulus ?

4. <360-2048> size of the key modulus [360-2048]

Todd(config)#crypto key generate rsa general-keys modulus 1024
