How to Configure Cisco Password

How to configure Cisco Consol, AUX, Telnet, Enable and Enable secret password.

Here are the five passwords you can set on a Cisco router:

• Console
• Aux
• VTY
• Enable password
• Enable Secret

Console: – This is the basic connection into every router. To initially set up a router, you need to connect to the console port.

Configuration of Consol password.

R1(config)#line consol 0

R1(config-line)#password cisco

R1(config-line)#login

Configuration of an Auxiliary password.

AUX: -On some routers, aux is called the auxiliary port, and on some, it is called the aux port.

R1(config)#line aux 0

R1(config-line)#password cisco

R1(config-line)#login

Configuration of VTY (telnet) password

The Virtual Teletype (VTY) lines are used to configure Telnet access to a Cisco router remotely.

R1(config)#line vty 0 4

R1(config-line)#password cisco

R1(config-line)#login

Enable Password

The Enable password is used to allow security on a Cisco router when an administrator is trying to go from user mode to privileged mode. The Enable password is an old, unencrypted password

R1(config)#enable password cisco

Enable Secret

Enable Secret provides better security since the password is kept encrypted using irreversible encryption algorithm.

R1(config)#enable secret cisco123

Encrypting your passwords
The Line command passwords (console, aux, and VTY) are not encrypted by default and can be seen by going into privileged EXEC mode and typing the command
show running-config

Router(config)#service password-encryption

After service password-encryption enable.
